А

абсолютный контакт: Связка , против короля называется абсолютной поскольку связанная фигура не может по закону выйти за линию атаки (поскольку ее перемещение подвергнет короля опасности ) . ^[1] См. относительный штифт .
активный: Описывает фигуру , которая угрожает нескольким полям или имеет несколько полей, доступных для следующего хода. Это также может описывать агрессивный стиль игры. ^[2] Антоним: пассивный .
отсрочка: Приостановка шахматной партии с намерением завершить ее позже. Когда-то это было очень распространено на соревнованиях высокого уровня, часто возникало вскоре после первого контроля времени , но от него по большей части отказались из-за появления компьютерного анализа. ^[3] См. также запечатанный ход .
adjudication: A way to decide the result of an unfinished game. A tournament director, or an impartial and strong player, will evaluate the final position and assign a win, draw, or loss assuming best play by both players.^[4]
adjust: See touch-move rule. To adjust the position of a piece on its square without being required to move it. A player may do this only on their turn, and must first say "I adjust", or the French equivalent "J'adoube".^[5]
advanced pawn: A pawn that is on the opponent's half of the board (the fifth rank or higher for White; the fourth rank or lower for Black). An advanced pawn may be weak if it is overextended, lacking support and difficult to defend, or strong if it cramps the enemy by limiting mobility. An advanced passed pawn that threatens to promote can be especially strong.^[6]
advantage: A better position with the chance of winning the game. Evaluation factors can include space, time, material, and threats.^[2]
Alekhine's gun: A special form of battery in which a queen backs up two rooks on the same file.^[7]
algebraic notation: The standard way to record the moves of a chess game, using alphanumeric coordinates for the squares.^[8] Also called standard notation.^[9] Abbr. AN.
amateur: Any player whose main occupation is not chess.^[10] The distinction between professional and amateur is not very important in chess as amateurs may win prizes, accept appearance fees, and earn any title, including World Champion.^[10]^[11] In the 19th century, "Amateur" was sometimes used in published game scores to conceal the name of the losing player in a Master vs. Amateur contest. It was thought to be impolite to use a player's name without permission, and the professional did not want to risk losing a customer.^[11] See also NN.
analysis: The study of a game or a position, in order to evaluate the quality of the moves and various other aspects of the game or position. At the end of a game, the players will often do an analysis of the game. See also post-mortem.^[2]
annotation: Written commentary on a game or a position using words, chess symbols, and/or notation.^[2]
announced mate: A practice, common in the 19th century, whereby a player would announce a sequence of moves, believed by them to constitute best play by both sides, that led to a forced checkmate for the announcing player in a specified number of moves (for example, "mate in five").^[12]
antipositional: A move or a plan that is not in accordance with the principles of positional play.^[13] Antipositional is used to describe moves that are part of an incorrect plan rather than a mistake made when trying to follow a correct plan. Antipositional moves are often pawn moves; since pawns cannot move backwards to return to squares they have left, their advance can create irreparable weaknesses.^[14]
Anti-Sicilian: An opening variation that White uses against the Sicilian Defense (1.e4 c5) other than the most common plan of 2.Nf3 followed by 3.d4 cxd4 4.Nxd4 (the Open Sicilian). Some Anti-Sicilians include the Alapin Variation (2.c3), Moscow Variation (2.Nf3 d6 3.Bb5+), Rossolimo Variation (2.Nf3 Nc6 3.Bb5), Grand Prix Attack (2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 and now 5.Bc4 or 5.Bb5), Closed Sicilian (2.Nc3 followed by g3 and Bg2), Smith–Morra Gambit (2.d4 cxd4 3.c3), and Wing Gambit (2.b4).^[15]
Arabian mate: A checkmate that occurs when the knight and rook trap the opposing king in a corner.^[16]
arbiter: An official responsible for overseeing chess tournaments and ensuring that the rules of chess are obeyed.
arena: A type of tournament without a fixed amount of rounds.^[17]
Armageddon game: A game that is guaranteed to produce a decisive result, because if there is a draw it is ruled a victory for Black. In compensation for this White is given more time on the clock. Often White is given five minutes, and Black four. This format is typically used in playoff tiebreakers when shorter blitz games have not resolved the tie.^[18]
artificial castling: Refers to a maneuver of several separate moves by the king and by a rook where they end up as if they had castled. Also known as castling by hand.^[19]
attack: An aggressive action on a part of the chessboard, or to threaten the capture of a piece or pawn.^[20] See also counterattack, discovered attack, double attack, mating attack, and minority attack. Antonym: defense.
attraction: A type of decoy involving a sacrifice of a minor or major piece on a square next to the enemy king, forcing the king to abandon the defense of another square. For example (see diagram), the black queen has interposed to block a check from the white queen, and White can check the king from the opposite direction to win the queen.^[21]
automaton: An automaton is a self-operating machine. In chess, it refers to chess-playing machines that were in fact hoaxes and under the control of hidden human players. Automatons stirred up great interest in the 18th and 19th centuries and inspired early thoughts of the possibility of artificial intelligence. By far, the most famous chess-playing "automaton" was The Turk, whose secret of human control was kept for a very long time. The first true automaton El Ajedrecista was created by Leonardo Torres y Quevedo.

B

B: Symbol used for the bishop when recording chess moves in English.^[22]
back rank: A player's first rank (the rank on which the pieces stand in the starting position). White's back rank is Black's eighth rank; Black's back rank is White's eighth rank.^[23] Also called home rank and first rank.
back-rank mate: A checkmate delivered by a rook or queen along a back rank from which the mated king is unable to move because it is blocked by friendly pieces (usually pawns) or squares under attack on the player's second rank.^[23] Also called back-row mate.
back-rank weakness: A situation in which a player is under threat of a back-rank mate and, having no time/option to create an escape for the king, must constantly watch and defend against that threat, for example by keeping a rook on the back rank.^[23]
backward pawn: A pawn that is behind a pawn of the same color on an adjacent file and that cannot be advanced with the support of another pawn.^[24]
bad bishop: A bishop that is hemmed in by the player's own pawns.^[25] Cf. good bishop.
bare king: A position in which a king is the only man of its color on the board.^[26]
Basque chess: Or Basque system. A chess competition in which the players simultaneously play each other two games on two boards, each playing White on one and Black on the other. There is a clock at both boards. It removes the bonus in mini-matches of playing White first. Basque chess was first played in the 2012 Donostia Chess Festival in the Basque Country, Spain.^[27]
battery: Gathering pieces along a line of action in somewhat varying setups. In games, it usually means to line up rooks and/or the queen on a file, or to place a bishop and a queen on a diagonal.^[20] In chess problems, battery refers to an arrangement of two pieces in line with the enemy king on a rank, file, or diagonal so that if the middle piece moves a discovered check (or a threat other than a check) will be delivered.^[28] See also Alekhine's gun.
BCF: British Chess Federation, the former name of the English Chess Federation.^[29] See also ECF.
BCM: An abbreviation for the British Chess Magazine.^[30]
BCO: An abbreviation for the 1982 openings reference book Batsford Chess Openings, by Raymond Keene and Garry Kasparov. The second edition (1989) is often called BCO-2.^[31] Cf. ECO and MCO.
best play: The theoretical absolute and ideal best moves from any given position.^[32]
big pawn: A bad bishop stuck behind its own pawns and defending them—effectively doing the work of a pawn.^[33]
bind: A strong grip or stranglehold on a position that is difficult for the opponent to break. A bind is usually an advantage in space created by advanced pawns. The Maróczy Bind is a well-known example.^[34] See also squeeze.
bishop: A piece that may move along diagonals without jumping.
bishop pair: The player with two bishops is said to have the bishop pair. Two bishops are able to control the diagonals of both colors. In open positions, two bishops are considered to have an advantage over two knights, or a knight and a bishop.^[20] Also called the two bishops.
bishop pawn: Or bishop's pawn. A pawn on the bishop's file, i.e. the c-file or f-file. Sometimes abbreviated "BP".^[35]
bishops on opposite colors: Or bishops of opposite colors. A situation in which one player has only a light-square bishop remaining while the other has only a dark-square bishop remaining. In endgames, this often results in a draw if there are no other pieces than pawns, even if one side has a material advantage of one, two or even three pawns, since the bishops control different squares (see Opposite-colored bishops endgame). In the middlegame, however, the presence of opposite-colored bishops imbalances the game and can lead to mating attacks, since each bishop attacks squares that cannot be covered by the other.^[36]
black: The dark-colored squares on the chessboard are often referred to as "the black squares" even though they are often some other dark color. Similarly, "the black pieces" are sometimes actually some other (usually dark) color.^[37] See also white.
Black: The designation for the player who moves second, even though the pieces ("the black pieces") are sometimes actually some other (usually dark) color.^[38] See also White and first-move advantage.
blind chess: See Kriegspiel.
blindfold chess: A form of chess in which one or both players are not allowed to see the board.^[39]
blind pigs: A pair of rooks on the opponent's second rank are referred to as "pigs" as they tend to devour pawns and pieces, and "blind pigs" if they cannot find the mate.^[40]
blitz chess: [from German: Blitz, "lightning"] A fast form of chess with a very short time limit, usually three or five minutes per player for the entire game. With the advent of electronic chess clocks, the time remaining is often incremented by one or two seconds per move.^[41]
blitzkrieg: A blitzkrieg is sometimes used to describe a quick attack on the f7- or f2-square early in the game.^[42]^[43]
blockade: The placement of a piece directly in front of an enemy pawn, where it obstructs the pawn's advance, and hinders the movements of the other enemy pieces. The enemy pawn provides some shelter to the piece that is blocking it, thereby protecting it from attacks by enemy pieces. A blockade is most effective against passed or isolated pawns. The ideal piece to use as a blockader is the knight. This strategy was famously formulated by Aron Nimzowitsch in 1924.^[44]^[45]
blocked position: A position where both sides are constrained from making progress, typically by interlocking pawn chain(s) dividing the available space into two camps.^[46] See also closed game.
blunder: A very bad move, an oversight (indicated by "??" in chess annotation).^[20]
board: 1. See chessboard.; 2. An assignment in team chess, e.g. first board, second board, etc.
board one: See first board.
Boden's Mate: Boden's Mate, named for Samuel Boden, is a checkmate pattern in which the king, usually having castled queenside, is checkmated by two crisscrossing bishops. Immediately prior to delivering the mate, the winning side typically plays a queen sacrifice on c3 or c6 to set up the mating position.^[47]
book draw: An endgame position known to be a draw with perfect play. Historically this was established by reference to chess endgame literature, but in simplified positions computer analysis in an endgame tablebase can be used.^[48] Also called theoretical draw.
book move: An opening move found in standard reference books on opening theory. A game is said to be "in book" when both players are playing moves found in the opening references. A game is said to be "out of book" when the players have reached the end of the variations analyzed in the opening books, or if one of the players deviates with a novelty (or a blunder).^[49]
book win: An endgame position known to be a win with perfect play. Historically this was established by reference to chess endgame literature, but in simplified positions (currently seven pieces or fewer) computer analysis in an endgame tablebase can be used.^[50]
break: A move that gains space and therefore freedom of movement, or the opening of a blocked position by the advance or capture of a pawn.^[51] See also pawn break.
breakthrough: Penetration of the opponent's position, or destruction of the defense, often by means of a sacrifice.^[20]
brevity: [chiefly British] See miniature.
brilliancy: A game that contains a spectacular, deep and beautiful strategic idea, combination, or original plan.^[51]
brilliancy prize: A prize awarded at some tournaments for the best brilliancy played in the tournament.^[52]
Bronstein delay: A time control method with time delay, invented by David Bronstein. When it becomes a player's turn to move, the clock waits for the delay period before starting to subtract from the player's remaining time.^[53]
bughouse chess: A popular chess variant played with teams of two or more.^[54]
building a bridge: Making a path for a king in the endgame by providing protective cover against checks from line pieces. A well-known example is the Lucena position.^[55]
bullet chess: Each side has one minute to make all their moves.^[56]
bust: [colloq.] A refutation of an opening, an opening line, a tactic, or a previously published analysis.^[57]^[58]
bye: A tournament round in which a player does not have a game, usually because there are an odd number of players. A bye is normally scored as a win (1 point), although in some tournaments a player is permitted to choose to take a bye (usually in the first or last round) and score it as a draw (½ point).^[58]

C

Caïssa: Known as the goddess or muse of chess, whose name is taken from a nymph in a 1763 poem, Caïssa or The Game at Chess, by Sir William Jones.^[59]
calculate: To plan mentally a series of moves and consider possible responses, without actually moving the pieces.^[20]
Candidate Master: A chess title ranking below FIDE Master.^[60] Abbr. CM.
candidate move: A move that seems good upon initial observation of the position, and that warrants further analysis.^[61]
Candidates Match: A knockout match in the Candidates Tournament.^[62]
Candidates Tournament: A tournament organised by the FIDE, the third and last qualifying cycle of the World Chess Championship. The participants are the top players of the Interzonal tournament plus possibly other players selected on the basis of rating or performance in the previous candidates tournament. The top ranking player(s) qualify(ies) for the world championship.^[63]
can opener: [colloq.] The plan of attacking a kingside position (sometimes a fianchettoed one) by advancing the h-pawn with the intention of opening a file near the defender's king.^[64]^{[verification needed]}
capped piece: A particular piece with which one player attempts to deliver checkmate. The requirement to checkmate with the capped piece constitutes a handicap. When the capped piece is a pawn, it is called a pion coiffé [from French, "capped pawn"].^[65]
capture: A move by a pawn or piece that removes from the board the opponent's pawn or piece. The capturing piece then occupies the square of the captured piece, except in the case of a capture that is done en passant.^[66]
castling: A move in which the king and a rook are moved at the same time. It moves the king from the center to a flank where it usually is safer, and it develops the rook. It is the only time two pieces are moved in a turn. Castling can be done on either the kingside (notated 0-0) or the queenside (0-0-0). Castling cannot be done in reply to a check, nor if the king were to cross or land on a square which is under attack by the opponent, nor if either the king or the rook involved has already moved.^[67]^[68]
castling into it: A situation where one side castles and a result is that the king is in more danger at the destination than on the initial square, either immediately or because lines and diagonals can be more readily opened against it.^[69]
castling long: Castling queenside; in chess notation: 0-0-0.^[67] Also called long castling.^[70]
castling rights: The ability to castle under the laws of chess.
castling short: Castling kingside; in chess notation: 0-0.^[67] Also called short castling.^[70]
casual game: See friendly game.
category of a tournament: The category of a tournament is a measure of its strength based on the average FIDE rating of the participants. The category is calculated by rounding up the number: (average rating − 2250) ÷ 25. So each category covers a 25-point rating range, starting with Category 1 which spans ratings between 2251 and 2275. A Category 18 tournament has an average rating between 2676 and 2700.^[71]
CC: An abbreviation sometimes used for correspondence chess or for chess club.
center: Or centre. The four squares in the middle of the board.^[72] See also expanded center. Sometimes short for pawn center. A king "in the center" can refer to an uncastled king on a center file.
center file: Or centre file. The king's file (e-file) or queen's file (d-file).
center pawn: Or centre pawn. A pawn on the king's file (e-file) or queen's file (d-file).^[73]
centipawn: A unit of evaluation used by chess engines, e.g. an evaluation of +1.32 is worth 20 centipawns more than an evaluation of +1.12. Historically a centipawn corresponded to a material value of 0.01 of a pawn; however, the strongest modern engines no longer rate pawns as worth 1.^[74]
central file: See center file.
centralization: Moving a piece or pieces toward the center of the board, where they will not only control the center, but also extend their influence to other areas. Pieces are best placed near the center of the board, because they increase their power and maneuverability. Knights in particular benefit from being centralized.^[75] Antonym: decentralization.^[76]
central pawn: See center pawn.
cheapo: Slang for a primitive trap, often set in the hope of swindling a win or a draw from a lost position.^[77] Also called cheap shot.
check: A direct attack on the king by an enemy man. The attacked king is said to be in check. There are only three possible immediate responses to a check: capturing the attacking piece, moving the king to an unattacked square, or interposing a piece between the attacker and the king. In casual games a player usually announces "check"; however, this is not a requirement in tournament games.^[78]
checkmate: Often shortened to mate. A position in which a player's king is in check and the player has no legal move (i.e. cannot move out of or escape the check). A player whose king is checkmated loses the game.^[79]
chess annotation: See annotation.
chess blindness: The failure of a player to see a good move or danger that should normally be considered obvious. The term was coined by Siegbert Tarrasch. Similar to Kotov syndrome.^[80]
chessboard: The chequered board used in chess, consisting of 64 squares (eight rows by eight columns) arranged in two alternating colors, light and dark.^[81]
chess clock: A device made up of two adjacent clocks and buttons, keeping track of the total time each player takes for their moves. Immediately after moving, the player hits their button, which simultaneously stops their clock and starts their opponent's. The picture shown displays an analogue clock where the term flag fall originates. Modern clocks are digital.^[82]
chess club: An in-person, local chess play organization.
chessmen: The movable figures placed on the board in a game of chess. Includes both pieces and pawns.^[83] Singular: chessman.
chess notation: See notation.
chess opening: See opening.
chess problem: Also called composition.
chess set: The thirty-two pieces required for a game, plus a chessboard.
chess variant: A chess-like game played using a board, pieces, or rules different from standard chess.^[84]
Chess960: A synonym for Fischerandom.
chop wood: Slang for capturing or exchanging pieces.^[85] See also wood.
classical: 1. An opening system geared towards forming a full pawn center. Classical ideas were challenged by hypermodern ideas.^[72]; 2. A game using a longer time control such as 40/2; the opposite of fast chess categories such as rapid, blitz or bullet.^[86]
classical bishop sacrifice: See Greek gift sacrifice.
clearance: Removal of piece from a square, rank, file or diagonal so that another piece may use it. It often involves sacrificing the piece that blocked the position.^[87] See Clearance sacrifice.
clock move: In a game played clock move, a move is considered completed only after the clock is pressed. For example, one could touch a piece, then move a different piece—as long as the player has not pressed their clock button. This way of playing is uncommon but can be seen in casual games or blitz games.^[88]
clock time: Time (consumed or remaining) on the chess clock, in a tournament game.^[89]
closed file: A file on which White and Black each have a pawn.^[90]
closed game: Or close game. A closed game has few open lines (files or diagonals). It is generally characterized by interlocking pawn chains, cramped positions with few opportunities to exchange, and extensive maneuvering behind lines. Such a game may evolve and later become an open game.^[91] Cf. open game. See also positional play.
Closed Game: A Closed Game is a particular opening that begins with the moves 1.d4 d5. It is also known as a Double Queen's Pawn Opening or Double Queen's Pawn Game.^[92] See also Open Game and Semi-Open Game.
closed tournament: A tournament in which only invited or qualifying players may participate. Also called invitational tournament. Cf. open tournament.
CM: An abbreviation for the Candidate Master title.
coffeehouse: Adjective used to describe a move, player, or style of play characterized by risky, positionally dubious play that sets traps for the opponent. The name comes from the notion that one would expect to see such play in skittles games played in a coffeehouse or similar setting, particularly in games played for stakes or blitz chess. The Blackburne Shilling Gambit is a typical example of coffeehouse play.^[93]
color: Or colour. The white or black pieces, and the white or black squares. The actual pieces and squares may be other colors, usually light and dark, but they are referred to as white and black.^[83] See White and Black in chess.
colorbound: Or colourbound. The property of a piece to access only squares of one color. In standard chess, each bishop is colorbound to either the white or black squares.
colors reversed: Or colours reversed. With colors reversed refers to opening moves by White normally played by Black, or vice versa. An example is the King's Indian Attack, where White's opening setup mirrors Black's setup in the King's Indian Defense. In such openings, White necessarily has an extra tempo compared to Black. Also called a reverse opening.^[94]
combination: A sequence of moves, including forced moves, and often involving a sacrifice, to gain an advantage.^[72]
compensation: That which is gained in return for a loss – often a positional improvement in return for loss of material. If material is sacrificed there may be a gain in development, or if a minor piece is exchanged for two or three pawns, the pawns would be the compensation.^[95]
computer move: A move that seems likely to have been played by a computer rather than a human, either because the move seems counterintuitive, or to not make immediate sense, or to eventually make sense but not until deep into the game. Computer moves seem to be what they are: moves based on millions of brute-force calculations, and not on intuition, aesthetics, or emotion. A computer move would overlook a dramatic capture that might cause an opponent to immediately resign, in favor of an obscure move that may turn out to be only slightly better. At one time the term was used disparagingly, but its meaning has evolved as computers have improved. It is occasionally used to suggest that a player has been assisted by computer.^[96]^[97]
connected passed pawns: Passed pawns on adjacent files. These are considered to be unusually powerful (often worth a minor piece or rook if on the sixth rank or above and not properly blockaded) because they can advance together.^[72] See also connected pawns.
connected pawns: Refers to two or more pawns of the same color on adjacent files.^[75] Cf. isolated pawns.
connected rooks: Two rooks of the same color on the same rank or file with no pawns or pieces between them. Connected rooks are usually desirable. Players often connect rooks on their own first rank or along an open file.^[98] See also doubled rooks.
consolidation: The improvement of a player's position by the reposition of one or more pieces to better square(s), typically after a player's attack or combination has left their pieces in poor positions or uncoordinated.^[99]
consultation game: A game in which two or more players consult with each other to jointly decide the moves for one side. Consultation games may also involve teams of two or more players playing on both sides.^[100]
continuation: See variation.
control: When a player's pawn, piece or pieces guard a square, or squares, or a file, or a rank in such a way that the territory can be advantageously used; and the opponent is prevented from using the territory.^[101] Also, the player that has the initiative has control.
control of the center: Having one or more pieces that attack any of the four center squares; an important strategy, and one of the main aims of openings.^[102]
cook: In chess problems, an unintended duplicate solution, or a refutation.^[103] See also Glossary of chess problems § cook.
coordination: The quality of multiple pieces working together, mutually supporting and complementing one another.^[104]
corr.: An abbreviation for correspondence game.
correspondence chess: Chess played at a long time control by long-distance correspondence. Traditionally correspondence chess was played though the post; today it is usually played over a correspondence chess server or by email. Typically, one move is transmitted in every correspondence.^[105]
corresponding squares: Corresponding squares are pairs of squares such that when a king moves to one square, it forces the opponent's king to occupy the other square in order to hold the position. If the opponent's king cannot move to the required square it is zugzwang and a disadvantage. Corresponding squares usually occur in pawn endgames. The theory of corresponding squares has developed to include complex calculations based on math-like formulas.^[106] Also called related squares. Cf. opposition.
counterattack: An attack that responds to an attack by the opponent.^[107]
countergambit: A gambit offered by Black, for example the Greco Counter Gambit, usually called the Latvian Gambit today (1.e4 e5 2.Nf3 f5?!); the Albin Countergambit (1.d4 d5 2.c4 e5); and the Falkbeer Countergambit (1.e4 e5 2.f4 d5). An opening need not have "countergambit" in its name to be one, for instance the Benko Gambit (1.d4 Nf6 2.c4 c5 3.d5 b5); the Englund Gambit (1.d4 e5?!); the Budapest Gambit (1.d4 Nf6 2.c4 e5); the Blackburne Shilling Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4?!); and many lines of the Two Knights Defense (e.g. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 and now 4...Bc5!? [the Wilkes–Barre Variation or Traxler Counterattack]; 4...Nxe4?!; 4...d5 5.exd5 Na5 6.Bb5+ c6 [the main line]; 4...d5 5.exd5 Nd4 [the Fritz Variation]; and 4...d5 5.exd5 b5 [the Ulvestad Variation]) are all examples of countergambits.^[108]
counterplay: The defending side's own aggressive action.^[109]
country move: A disparaging term for a move considered unsophisticated, especially an unnecessary single-step advance of the rook's pawn in the opening. The term was popular in London in the late 19th century.^[110]
cover: To protect a piece or control a square.
cramped: Having limited mobility in a position.^[111]
critical position: The moment in a game or opening when the evaluation shows that things are about to change, either towards an advantage for one player, or towards equality; a wrong move can be disastrous.^[109]
critical square: See key square.
cross-check: A cross-check is a check played in reply to a check, especially when the original check is blocked by a piece that itself either delivers check or reveals a discovered check from another piece.^[112]
crosstable: An arrangement of the results of every game in a tournament in tabular form. The names of the players run down the left side of the table in numbered rows. The names may be listed in order of results, alphabetically, or in pairing order, but results order is most common. There may be one column for each successive round, or, in a round-robin tournament, there may be one column for each player, with the players in the same order in the columns as in the rows. For each player, the table cells on the player's row record the results of the player's games, using 1 for a win, 0 for a loss, and ½ for a draw. (In a double round-robin tournament each cell contains two entries, as each pair of players plays two games alternating White and Black.)^[113] For examples see Hastings 1895 chess tournament, Nottingham 1936 chess tournament, and AVRO tournament.
crush: Slang for a quick win, especially an overwhelming attack versus poor defensive play. A crushing move is a decisive one.

D

dark-square bishop: One of the two bishops that moves only on the dark squares. In the starting position, White's dark-square bishop is on c1; Black's is on f8.^[38] Often shortened to dark bishop^[76] or DSB. Cf. light-square bishop.
dark squares: The 32 dark-colored squares on the chessboard, such as a1 and h8. A dark square is always located at a player's left-hand corner.^[38] Cf. light squares.
dead draw: A drawn position in which neither player has any realistic chance to win. In the strict sense, dead draw may refer to a position in which it is impossible for either player to win (such as insufficient material). In a broader sense, it may refer to a simple, lifeless position that would require a major blunder before either side would have a chance to win.^[114]
dead position: A position where neither player can mate the opponent's king with any series of legal moves (e.g. knight and king against a bare king). This position is drawn.^[116]
decoy: This is a tactic used to lure an enemy man away from its defensive position.^[117]^[118] See also deflection and attraction.
defense: 1. A move or plan to meet the opponent's attack.^[109]; 2. Part of the name of openings played by Black; e.g. the Scandinavian Defense, King's Indian Defense, English Defense, etc.^[109]
deflection: A decoy tactic that involves luring an enemy piece away from a good square; typically, away from a square on which it defends another piece or threat. Deflection is thus closely related to overloading.^[119] See also attraction.
demonstration board: A large standing chess board used to analyze a game or show a game in progress. Johann Löwenthal invented the demonstration board in 1857.^[120]
descriptive notation: A system of recording chess moves, used primarily in the English and Spanish speaking countries until the 1980s. Descriptive notation is based on natural language descriptions of chess moves rendered in abbreviated form, for example "pawn to queen's bishop's fourth" is rendered as "P-QB4". Now replaced by the standard algebraic notation.^[121]
desperado: A piece that seems determined to give itself up, typically to bring about stalemate or perpetual check. Also an en prise or trapped piece that sacrifices itself for the maximum compensation possible.^[122]
development: The movement of non-pawn pieces in the opening from their original squares to squares where they can be more active. Development of one's pieces is one of the objectives of the opening phase of the game.^[117]
diagonal: A line of squares of the same color touching corner to corner, along which a queen or bishop can move.^[123]
discovered attack: An attack made by a queen, rook or bishop when another piece or pawn moves out of its way.^[117]
discovered check: A discovered attack to the king. This occurs when a player moves a piece, resulting in another piece putting their opponent's king in check.^[124]
diversionary sacrifice: Especially in the middlegame, the sacrifice of a decoy piece.^[125]
domination: From endgame studies, control of all movement squares of an enemy piece.^[126]
double attack: Two attacks made with one move: these attacks may be made by the same piece (in which case it is a fork); or by different pieces, for example in a discovered attack when the moved piece also makes a threat.^[117]
double check: A check delivered by two pieces at the same time. A double check necessarily involves a discovered check. By its nature a double check cannot be met by interposing a defending piece in the line of attack, or by capturing an attacker; when subjected to a double check, the attacked king must move, which makes the double check especially powerful as an attacking tactic.^[127]
doubled pawns: Two pawns of the same color on the same file; generally considered a weakness due to their inability to defend each other.^[123]
doubled rooks: A powerful configuration in which a player's two rooks are placed on the same file or rank with no other men between them. They defend each other and attack along the shared file or rank, as well as two additional ranks or files. The configuration can be especially decisive in the endgame.^[128]
double fianchetto: A player's king bishop and queen bishop have both been fianchettoed.^[129]
draw: A game that ends without victory for either player. Most drawn games are draws by agreement. The other ways that a game can end in a draw are by stalemate, by a dead position, by the threefold repetition rule, by the fifty-move rule, by the fivefold repetition rule and by the seventy-five-move rule. A position is said to be a draw (or a "drawn position" or "theoretical draw") if either player can, through correct play, eventually force the game into a position where the game must end in a draw, regardless of the moves made by the other player. A draw is usually scored as ½ point, although in some matches only wins are counted and draws are ignored.^[117]
draw by agreement: A game that is ended by both players' accepting a draw.^[130] See also resign.
draw death: Hypothetical scenario whereby elite-level chess players, aided by modern computer analysis, become so good that they never make mistakes, leading to endless drawn games (since chess is widely believed to be drawn with best play from both sides).^[131]
drawing line: An opening variation that commonly ends in a draw.^[132]
drawing weapon: An opening line played with the intent of drawing the game.^[133]
drawish: An adjective describing a position or game that is likely to end in a draw.^[134]
draw odds: A type of chess handicap where one player (Black in an Armageddon game) has only to draw in order to win the match.^[135]
draw offer: A proposal by a player to the opponent that the game be drawn by agreement.^[136]
dynamism: A style of play in which the activity of the pieces is favored over more positional considerations, even to the point of accepting permanent structural or spatial weaknesses. Dynamism stemmed from the teachings of the Hypermodern school and challenged the dogma found in more classical teachings, such as those put forward by Wilhelm Steinitz and Siegbert Tarrasch.^[137]

E

eat: [colloq.] To remove the opponent's piece or pawn from the board by taking it with one's own piece or pawn.^[138]^[139] See also capture.

ECU: The European Chess Union (ECU) is the continental association for chess in Europe.
ECO: The Encyclopaedia of Chess Openings (ECO), a standard and comprehensive chess opening reference. Also a classification system (ECO code) for openings that assigns an alphanumeric code from A00 to E99 to each opening.
edge: A small but meaningful advantage in the position against one's opponent. It is often said White has an edge in the starting position, since White moves first (see First-move advantage in chess).^[140]
eighth rank: The rank on which pawns promote (rank eight for White; rank one for Black). Also called last rank.
Elo rating system: The Elo rating system is a method for calculating the relative skill levels of chess players, named after Arpad Elo. Since 2012, FIDE publishes a monthly international chess rating list using the Elo system.^[141]

endgame tablebase: A computerized database of endgames with a small number of pieces, providing perfect play for both players, and thus completely solving those endgames. As of 2012, tablebases have been calculated for all positions with up to seven pieces.^[142]
en passant: [from French, "in the act of passing"] The rule that allows a pawn that has just advanced two squares to be captured by an enemy pawn that is on the same rank and adjacent file. The pawn can be taken as if it had advanced only one square. Capturing en passant is possible only on the next move.^[143] Abbr. e.p.
en prise: [from French, "in a position to be taken",^[144]^[145] often italicized] En prise describes a piece or pawn exposed to a material-winning capture by the opponent. This is either a hanging piece, an undefended pawn, a piece attacked by a less valuable attacker, or a piece or pawn defended insufficiently. For instance, 1.e4 Nf6 2.Nf3? leaves White's e-pawn en prise.^[146]^[147]
e.p.: An abbreviation for en passant.
epaulette mate: A checkmate position where the king is blocked on both sides by its own rooks.^[148]
EPD: An abbreviation for Extended Position Description.
equalize: Or equalise. To reach a position where the players have equal chances of winning, referred to as equality, or a position that is equal. In the opening, because White has the advantage of the first move, the immediate goal for Black is to achieve equality.^[149]
escape square: See flight square.
evaluation: Or simply eval. The analysis of a position. A computer or engine evaluation is a means of assigning a number value to a position, based not on intelligence, but on algorithms, which vary from engine to engine and depend on engine strength. Engine evaluations have foibles and imperfections even when functioning as designed. If an engine describes a position as +2.50, the plus sign ("+") indicates the position is favorable to White; a minus sign ("−") indicates the position is favorable to Black. The number can correspond to the approximate value of pieces, although engines use other factors besides material. The notation +2.50 indicates that White is ahead by two and one-half pawns. The notation +M4 (or sometimes #4) indicates that White can force checkmate in four moves.^[150]^[151]^[152] Cf. analysis.
exchange: To swap or trade pieces by capture. Usually the pieces are of equal value (i.e., rook for rook, knight for knight, etc.), or of bishop for knight (two pieces that are considered approximately equal in value).^[153] Also called even exchange.
exchange, the: The advantage of a rook over a minor piece (knight or bishop). The player who captures a rook for a minor piece is said to have "won the exchange", the player who has lost the rook has "lost the exchange". An exchange sacrifice is giving up a rook for a minor piece.^[146]
exchange variation: This is a type of opening in which there is an early, voluntary exchange of pawns or pieces.^[154]
exhibition: Chess games played for the public in various formats and for various purposes, often to promote the game, or a particular match or player, or as a fundraiser. An exhibition may pit two masters against each other, and normally use chess clocks. In a simultaneous exhibition, one player takes on a number of opponents at once, and it is often not timed. A blindfold exhibition is the same but more challenging, since the exhibitor plays without seeing the boards.^[155]
expanded center: The central sixteen squares of the chessboard.^[156]
exposed king: A king lacking pawns to shield it from enemy attack.^[157]
extended fianchetto: See fianchetto.

fianchetto: To develop a bishop to the board's longest diagonal on the file of the adjacent knight (b2 or g2 for White; b7 or g7 for Black). The fianchetto of both bishops by a player is called a double fianchetto. Less common is to develop a bishop to the rook's file (a3 or h3 for White; a6 or h6 for Black), called extended fianchetto.^[129] The Italian word ("little flank") is pronounced /ˌfiənˈkɛtoʊ/ or /ˌfiənˈtʃɛtoʊ/ in English, while its name sounds like [fjaŋˈketto] in Italian.^[161]^[162]
FICGS Grandmaster: A correspondence chess title calculated by the FICGS (Free Internet Correspondence Games Server) organization.^[163]
FIDE: The World Chess Federation (Fédération Internationale des Échecs), the primary international chess organizing and governing body. The abbreviated name FIDE is nearly always used in place of the full name in French.^[164]
FIDE Master: A chess title ranking below International Master.^[165] Abbr. FM.
FIDE rating: See Elo rating system.
fifty-move rule: A draw may be claimed if no capture or pawn move has occurred in the last fifty moves by either side.^[166] For the occurrence of seventy-five such moves, see seventy-five-move rule.
file: A column of the chessboard. A specific file can be named either using its position in algebraic notation, a–h, or by using its position in descriptive notation. For example, "f-file" and "king bishop file" both denote the squares f1–f8 (or KB1–KB8 in descriptive notation).^[164]
fingerfehler: [from German, "finger mistake"] An error caused by unthinkingly touching the wrong piece or releasing a piece on the wrong square, forcing the player to move that piece in accordance with the touch-move rule.^[167]
first board: In team chess, the player who is assigned to face the strongest opponents. Also called top board and board one. Second board faces the next strongest players, followed by third board, and so on.

first-move advantage: The slight (by most accounts) advantage that White has by virtue of moving first.^[164]
first player: The expression "the first player" is sometimes used to refer to White.
first rank: See home rank.
Fischerandom: Also known as Chess960. A variation of chess invented and advocated by Bobby Fischer. The pieces and pawns have their normal moves, but the setup of pieces on the first rank is random, except that two rules must be followed: the king must be placed on a square between the rooks, and the bishops are placed on squares of opposite color. Black's pieces are placed opposite White's. Castling may be done; the special castling rules incorporate the normal castling in classic chess.^[168]^[169]
Fischer delay: A time control method with time delay, invented by Bobby Fischer. When it becomes a player's turn to move, the delay is added to the player's remaining time.^[170]
fish: [derogatory slang] A weak or easily defeated player or players. See also woodpusher.
fivefold repetition: A game is drawn if the same position occurs five times, with specific meaning of occurrence as under threefold repetition.^[171]

forced mate: A sequence of two or more moves culminating in checkmate that the opponent cannot prevent.^[175]
forced move: A move that is the only one to not result in a serious disadvantage for the moving player. Forced can also be used to describe a sequence of moves for which the player has no viable alternative, for example "the forced win of a piece" or "a forced checkmate". In these cases the player cannot avoid the loss of a piece or checkmate, respectively.^[174] Cf. forcing move.
forced win: A win guaranteed by a series of forcing moves.
forcing move: A move that presents a threat and limits the opponent's responses.^[176] Cf. forced move.
forfeit: Refers to losing the game by breaking rules, by absence or by exceeding the time control (forfeit on time).^[177]
fork: A simultaneous attack by a single piece on two (or more) of the opponent's pieces (or other direct target, such as a mate threat). When the attacker is a knight the tactic is often specifically called a knight fork. Some sources state that only a knight can give a fork and that the term double attack is correct when another piece is involved, but this usage is rare.^[5]
Forsyth–Edwards Notation: A standard notation for describing a particular board position of a chess game. The purpose of FEN notation is to provide all the necessary information to restart a game from a particular position.^[178]^[179] Abbr. FEN.
fortress: In endgame theory, a fortress is an impenetrable position which, if obtained by the side with a material disadvantage, may result in a draw due to the stronger side's inability to make progress.^[180]
frame: A square region of the board enclosing another region not part of the given frame, akin to a picture frame. Also referred to as a ring.^[181] The outer frame consists of the 28 squares along the edge of the board, the middle frame consists of the 20 squares just inside the outer frame, and the inner frame consists of the 12 squares just inside the middle frame.^[182] The notion of the frame may be expanded to include the center itself as the innermost frame. The mobility of pieces is closely related to the frame on which they stand. In general, a piece closer to the center has greater freedom of movement than a piece closer to the edge of the board.
friendly game: A game that is not played as part of a match, tournament, or exhibition. Often the game is not timed, but if a chess clock is used, rapid time controls are common. The term refers only to the circumstances in which the game is played, not the relationship between the players or the intensity of the competition.^[183] Also called casual game and informal game.
frontier line: An imaginary line dividing the board into two halves, passing between the fourth and fifth ranks.^[184]^[185] The frontier line separates White's side of the board from Black's side. Coined by Nimzowitsch.^[186]^[187]

GM: An abbreviation for Grandmaster.^[190]
God: Metaphorical; a hypothetical player who always plays perfectly.^[191]
good bishop: A bishop that has greater mobility, because the player's own pawns are on squares of color opposite to that of the bishop.^[192] See also bad bishop.
Grandmaster: The highest title a chess player can attain (besides World Champion). Awarded by FIDE, the title is valid for life unless exceptional circumstances (such as cheating) occur.^[193] Abbr. GM.
grandmaster draw: A game in which the players agree to a quick draw. Originally it referred to such games between grandmasters, but the term can now refer to any such game.^[193]

H

half-open file: A file on which only one player has pawns.^[195] Also called semi-open file.
handicap: See odds.
hanging: [colloq.] Unprotected and exposed to capture. A hanging piece may also be said to be en prise.^[193]
hanging pawns: Two pawns of the same color on adjacent files, with no pawns of the same color on the files to either side of them.^[193]
harmony: See coordination.
Harry: A nickname for the h-pawn, sometimes occurring in the expression, "Harry the h-pawn".^[196]^[197]
hauptturnier: German word that is freely translated as "candidates tournament". In the early part of the 20th century, it was necessary for the ambitious European amateur to win a succession of prizes in small tournaments, to progress to a higher level of competition. The creation of the hauptturnier enabled the process to become more formalized, and they became a regular feature of the major German chess congresses. Winning such an event conferred the title of 'Master of the German Chess Federation', and this, in turn, could be used to gain admittance to prestigious international tournaments. Some of the best players in chess history, such as Emanuel Lasker and Siegbert Tarrasch, secured their Master titles and advanced their chess careers in this way.^[198]
heavy piece: See major piece.
hole: A square that is inside or near a player's territory that cannot be controlled by a pawn. It is a gap in a player's pawn configuration, and especially dangerous when the hole is close to the center or near the king. A knight landing on a hole may be part of an attack. An example of a hole is e4 in the Stonewall Attack.^[199]
home rank: The rank on which the pieces stand in the starting position (rank one for White; rank eight for Black).^[200] Also called back rank and first rank.
horizontal line: See rank.
Horwitz bishops: A player's light-square and dark-square bishops placed so that they occupy adjacent diagonals, creating a potent attack. Also called raking bishops, and sometimes Harrwitz bishops.^[203]^[204]
human move: A move a human would make, as opposed to the kind of move that only a computer would make.^[205]
Hutton pairing: A pairing technique invented in 1921 by George Dickson Hutton for matching teams of players in which only one game is required per player. Has been used regularly for correspondence team events and for matches between many teams conducted on one day.^[206] Also called jamboree pairing.
hypermodernism: A school of thought that prefers controlling the center with pieces from the flanks as opposed to occupying it directly with pawns. Two major proponents of hypermodernism were Réti and Nimzowitsch.^[207] See also classical.

inactive: See passive.
in check: See check.
increment: Refers to the amount of time added to each player's time before each move. For instance, rapid chess might be played with "25 minutes plus 10 second per move increment", meaning that each player starts with 25 minutes on their clock, and this increments by 10 seconds after (or before) each move, usually using the Fischer Delay method.^[41] See Time control § Increment and delay methods.
Indian bishop: A fianchettoed bishop, characteristic of the Indian defenses, the King's Indian and the Queen's Indian.^[211]
Indian Defense: An opening that begins 1.d4 Nf6. Originally used to describe queen's pawn defenses involving the fianchetto of one or both black bishops; now used to describe all Black defenses after 1.d4 Nf6 that do not transpose into the Queen's Gambit.^[212]
informal game: See friendly game.
initiative: The ability to make attacking moves, and force the course of play. It is an aspect of time. The attacking player has the initiative, and the defending player attempts to seize it.^[213]
innovation: A synonym for theoretical novelty.
insufficient material: An endgame scenario in which all pawns have been captured, and one side has only its king remaining while the other has only its king, a king plus a knight, or a king plus a bishop. A king plus bishop versus a king plus bishop with the bishops on the same color is also a draw, since neither side can checkmate, regardless of play. Situations where checkmate is possible only if the inferior side blunders are covered by the fifty-move rule.^[214] See Draw (chess) § Draws in all games.
interference: The interruption of the line or diagonal between an attacked piece and its defender by interposing a piece.^[213]
intermediate move: See zwischenzug.

Internet chess server: An external server that provides the facility to play, discuss, and view chess over the Internet. Abbr. ICS.
interpose: To move a piece between an attacking piece and its target, blocking the line or diagonal of attack. Interposing is not possible if the attacker is a knight, king, or pawn, thus only possible in case of attacking rooks, bishops, or queens. Interposing a piece is one of the three possible responses to a check.^[5]
Interzonal tournament: A tournament organised by the FIDE starting from the 1950s to 1993. It was the second qualifying cycle of the World Chess Championship. The participants were selected from the top players of the Zonal tournaments. The top ranking players qualified for the Candidates Tournament. Since 1998 the winners of the zonal tournaments have played short matches against each other over a few weeks in a knockout-style competition to determine who is eligible for the Candidates Tournament.
IQP: An abbreviation for isolated queen pawn. See isolani.
irregular opening: Early 19th-century chess literature classified all openings that did not begin with either 1.e4 e5 or 1.d4 d5 as "irregular". As opening theory developed and many openings previously considered "irregular" became standard (e.g. the Sicilian Defense), the term gradually became less common. Opening books today are more likely to describe debuts such as 1.b4 (the Sokolsky Opening) as "uncommon" or "unorthodox".^[215]
isolani: Refers to a d-pawn with no pawns of the same color on the adjacent c-file and e-file, and is a synonym for isolated queen pawn. Aron Nimzowitsch, who coined the term, regarded the isolani as a weapon of attack in the middlegame but an endgame weakness; he saw the problem of hanging pawns as related.^[216] See also Pawn structure § Queen's Gambit – Isolani.
isolated pawn: A pawn with no pawn of the same color on an adjacent file.^[217]
isolated queen pawn: Or isolated queen's pawn. Abbr. IQP. See isolani.

The Italian bishop stands in contrast to the Spanish bishop on b5 characteristic of the Ruy Lopez. "Italian" may be used as an adjective for an opening where one or both players have Italian bishops.^[218]

J

j'adoube: (from French, "I adjust", pronounced [ʒa.dub]) The international signal of the intention to adjust the position of a piece on the board. When playing with the touch-move rule, a player must say this in order to be able to touch a piece without being subject to the touched piece rule. The verb adouber, literally "to dub" (raise to the knighthood), is rarely used in contemporary French outside of this context. A local language equivalent, e.g. "I am adjusting", is generally also acceptable.^[5]

K

K: Symbol used for the king when recording chess moves in English.^[22]
key square: 1. An important square.; 2. In pawn endings, a square whose occupation by one side's king guarantees the achievement of a certain goal, such as the promotion of a pawn or the win of a pawn.^[214]
KGA: The King's Gambit Accepted opening.
KGD: The King's Gambit Declined opening.
KIA: The King's Indian Attack opening.
kibitz: As a spectator, making comments on a chess game that can be heard by the players. Kibitzing on a serious game while it is in progress (rather than during a post-mortem) is a serious breach of chess etiquette.^[219]
kick: Attacking a piece, often a knight, with a pawn, so that it will move. Kicking a piece may lead to gaining a tempo, or may force the opponent to concede control of key squares.^[219]
KID: The King's Indian Defense opening.
king: The most important piece in chess. It may move to any adjacent square, and it may castle. A king threatened with capture is in check; a player cannot end their move with their king in check. If a player's king is in check and there is no escape, then the king is in checkmate, and the player loses. If the player whose turn it is has no legal moves and their king is not in check, then it is stalemate, and the game is drawn.
king bishop: Or king's bishop. The bishop that is on the kingside at the start of the game. Sometimes abbreviated "KB".^[83]
king hunt: A sustained attack on the enemy king that results in the king being driven a far distance from its initial position, typically resulting in its checkmate. Some of the most famous games featuring king hunts are Edward Lasker–Thomas, Polugaevsky–Nezhmetdinov, and Kasparov–Topalov.^[220] Also called king chase.
king knight: Or king's knight. The knight that is on the kingside at the start of the game. Sometimes abbreviated "KN".^[83]
king pawn: Or king's pawn. A pawn on the king's file, i.e. the e-file. Sometimes abbreviated "KP". Also king bishop pawn (KBP), king knight pawn (KNP), and king rook pawn (KRP) for a pawn on the f-, g-, or h-file, respectively.^[83]

king walk: A consecutive series of king moves designed to bring the king to a safer square. For example, if a player has castled kingside but the opponent has sacrificed a piece to destroy the kingside pawn cover, they may choose to walk the king over to the queenside to shelter behind the queenside pawns.^[221] See also King walk.
knight: A piece that may move to any nearest square not on a rank, file, or diagonal on which it stands. In other words, it may move two squares horizontally or vertically and then one square perpendicular to that (forming an L shape), jumping over any pieces in the way.
knight pawn: Or knight's pawn. A pawn on the knight's file, i.e. the b-file or g-file. Sometimes abbreviated "NP".^[83]
knight's tour: A puzzle that challenges a person to set a knight on an empty chessboard, and make the piece move around (as it moves in a chess game), but to visit every square only once. The knight's tour is the best known of a variety of tours and puzzles based on chess pieces. A closed tour (also known as a re-entrant tour) ends on the same square on which it began and needs 64 moves. An open tour ends on a different square and needs only 63 moves.^[222]
knockout tournament: See Single-elimination tournament. A tournament conducted as a series of matches in which the winner of each match advances to the next round and the loser is eliminated. Well-known chess tournaments held in the knockout format include London 1851 and the 2007 Chess World Cup. Cf. round-robin tournament and Swiss tournament.
Kotov syndrome: This phenomenon, described by Alexander Kotov in his 1971 book Think Like a Grandmaster, can occur when a player does not find a good plan after thinking long and hard on a position. The player, under time pressure, then suddenly decides to make a move that they have hardly thought about at all, and it may not be a good move for that reason.^[223]
Kriegspiel: [from German, "war game"] Kriegspiel is a chess variant played by two opponents who can see only their own board, and one monitoring umpire who makes the moves of both players on a neutral board. It requires three chess sets and boards. The players make their moves based on limited information from the umpire. It was introduced in 1898. It is sometimes referred to as blind chess, not to be confused with blindfold chess.^[224]
Kt: The symbol sometimes used for the knight when recording chess moves in descriptive notation, mainly in older literature. An N is used instead in algebraic notation and in later descriptive notation to avoid confusion with K, the symbol for the king.^[22]

L

last rank: See eighth rank.
laws of chess: The rules of chess.^[115]
lightning chess: A form of chess with an extremely short time limit, either blitz chess or bullet chess.^[225]
light-square bishop: One of the two bishops that moves only on the light squares. In the starting position, White's light-square bishop is on f1; Black's is on c8.^[214] Often shortened to light bishop.^[226] Cf. dark-square bishop.
light squares: The 32 light-colored squares on the chessboard, such as h1 and a8.^[227] Cf. dark squares.
line: 1. A sequence of moves, usually in the opening or in analyzing a position.; 2. An open path for a piece (queen, rook, or bishop) to move or control squares.^[225]
line piece: A piece whose movement is defined to be along straight lines of squares (i.e. the rook, bishop, and queen).^[228]
liquidation: See simplification.
long castling: See castling long.
long diagonal: One of the two diagonals with eight squares (a1–h8 or h1–a8).^[229]
long fianchetto: A fianchetto whereby the knight's pawn has advanced two squares (b4 or g4 for White; b5 or g5 for Black) instead of one.^[129]
long-range piece: A bishop, rook, or queen.
loose piece: A piece vulnerable to opponent attacks because it is undefended and cannot easily be withdrawn or supported.^[230]
loose position: A position vulnerable to opponent attacks because it is overextended or its pieces are uncoordinated.
losing a tempo: See tempo.
loss: A defeat for one of the two players, which may occur due to that player being checkmated by the other player, resigning, exceeding the time control, or being forfeited by the tournament director. In chess, a zero-sum game, this results in a win for the other player.^[231]
Lucena position: A well-known rook and pawn versus rook endgame position in which the player with the extra pawn can force a win by cutting off the opponent's king and placing a rook on the 4th rank in order to block the opponent's rook checks, thereby allowing the pawn to queen.^[55]
luft: [from German, "air"] Space made for a castled king to give it a flight square to prevent a back-rank mate. Usually luft is made by moving a pawn on the second rank in front of the king.^[232] See also flight square.

M

main line: The principal, most important, or most often played variation of an opening.^[233]
majority: A larger number of pawns on one flank opposed by a smaller number of the opponent's; often a player with a majority on one flank has a minority on the other.^[234] A central pawn majority is a larger number of pawns on the center files.
major piece: A queen or rook, also known as a heavy piece.^[235] The primary distinction of major pieces versus minor pieces is that major pieces are capable of checkmate with only their own king for support, as the enemy king is unable to step across the ranks and files they control. On an otherwise empty board, a major piece can move from any square to any other square in at most two moves.
man: A piece or a pawn, when the term "piece" is used as exclusive of pawns.^[236]
Maróczy Bind: A bind on the light squares in the center, particularly d5, obtained by White by placing pawns on c4 and e4. Named for Géza Maróczy, it originally referred to formations arising in some variations of the Sicilian Defense, but the name is now also applied to similar setups in the English Opening and the Queen's Indian Defense. It was once greatly feared by Black but means of countering it have been developed since the 1980s and earlier.^[237]
master: Loosely, a strong chess player who would be expected to beat most amateurs. It may also refer to a formal title such as International Master or National Master. Standards vary, but a master will usually have an Elo rating of over 2200.^[238]
match: The term "match" does not refer to an individual game of chess, but to either a competition between two teams or a series of games between two individuals. A match may be the entire competition, or it may be a round in a knockout tournament or team tournament. A match between individuals usually consists of several games, continuing until one of the players has achieved either a set score or a set number of wins.^[238]
mate: Short for checkmate.^[239]
material: A player's pieces and pawns on the board. The player with pieces and pawns of total greater value is said to have a material advantage. Gaining a material advantage is called winning material.^[240] See Chess piece relative value.
materialism: Playstyle characterized by a willingness to win material at the expense of positional considerations. Chess engines historically were often materialistic.^[241]
mating attack: An attack aimed at checkmating the enemy king.^[242]
mating net: A position or series of moves that leads to forced mate.^[242]
MCO: Modern Chess Openings, a popular chess opening reference. Often the edition is also given, as in MCO-14, the 14th edition. Cf. ECO.
middlegame: The part of a chess game that follows the opening and comes before the endgame, beginning after the pieces are developed in the opening. This is usually roughly moves 20 through 40.^[240]
miniature: A short game (usually no more than 20 to 25 moves), for example: 1.e3 e5 2.Qf3 d5 3.Nc3 e4 4.Qf4?? Bd6! and White resigned in Spiel–Künzel, Europe 1900,^[243] because the queen is trapped. However, some authors include games up to 30 moves.^[244] Usually only decisive games (not draws) are considered miniatures. Ideally, a miniature should not be spoiled by an obvious blunder by the losing side. A miniature may also qualify as a brilliancy. The Opera Game is a famous example. Sometimes called a brevity [chiefly British].^[52] See also Glossary of chess problems § miniature.
minor exchange: The exchange of a bishop for a knight.^[245]
minority: A smaller number of pawns on one flank opposed by a larger number of the opponent's; often a player with a minority on one flank has a majority on the other.^[234]
minority attack: An advance of pawns on the side of the board where one has fewer pawns than the opponent, an attack strategy usually carried out to provoke a weakness.^[240]
minor piece: A bishop or knight.^[240] Unlike major pieces, minor pieces are unable to contain the enemy king or block his advance alone, as he can simply pass through the holes in their line of attack. Compared to major pieces, minor pieces also find it difficult to navigate the entire board; a knight may require four moves to reach a square two squares away, while a bishop can only ever control half of all squares.
mobile pawn center: Pawns on central squares able to advance without becoming weak.^[246]
mobility: The ability of a piece(s) to move around the board. Having space.^[240]
mouse slip: A fumble by a player in the use of a computer control tool while playing chess on the Internet that results in an unintended move.^[247]
move: A full move is a turn by both players, White and Black. A turn by either White or Black is a half-move, or (in computer context) one ply.^[248]
move order: The sequence of moves one chooses to play an opening or execute a plan. Different move orders often have different advantages and disadvantages. A plan that uses certain moves can sometimes be improved by making the identical moves but in a different sequence.^[249] See also transposition.
mysterious rook move: Coined by Nimzowitsch to refer to the placing of a rook on a closed file in anticipation that the opponent is going to open the file. This move may either achieve a position with a rook on an open file, or it may alternatively hinder the opponent's intentions (prophylaxis). The meaning of the word has since expanded to refer to any rook move that appears to have a hidden purpose.^[250]^[251]

N

N: 1. Symbol used for the knight when recording chess moves in English.; 2. An abbreviation for novelty.
NCO: An abbreviation sometimes used for the chess opening reference Nunn's Chess Openings. Cf. ECO and MCO.
NN: Traditionally used in game scores to indicate a player whose name is not known. The origin is uncertain. It may be an abbreviation of the Latin nomina ("names"), or it may be short for the Latin phrase nomen nescio ("name unknown").^[252] Sometimes N.N.
norm: A step toward earning a chess title, such as Grandmaster or International Master. To qualify for the award of norms, a tournament must be rated by FIDE, must be sufficiently strong, must include a mix of nationalities, must include a specified number of titled players, and must meet certain other requirements regarding time control and playing conditions. The score necessary to qualify for a norm depends on the strength of the tournament. In practice, three norms are usually required for a title, though regulations have varied over the years.^[253]^[254]
notation: Any method of recording chess moves, allowing games to be later published, replayed and analyzed. The most common notation today is algebraic notation, which is used internationally. Formerly descriptive notation was standard in English language publications. There are also systems of notation for recording chess positions without the use of diagrams, the most common of which is Forsyth–Edwards Notation (FEN).^[255] Cf. annotation.
novelty: See theoretical novelty.

O

occupation: Occupation of a rank or file means a rook or queen controls it; occupation of a square means a piece or pawn sits on it.^[256]^[257]
octopus: A strongly positioned knight in enemy territory. A knight not near the edge reaches out in eight directions, like the eight tentacles of an octopus.^[258]
odds: This refers to the stronger player giving the weaker player some sort of advantage in order to make the game more competitive. It may be an advantage in material, in extra moves, in time on the clock, or some combination of those elements. Since the advent of the chess clock, time odds have become more common than material odds.^[259]
offhand game: See skittles.
Olympiad: An international team chess tournament organized biennially by FIDE. Each team represents a FIDE member country.
open file: A file on which there are no pawns.^[5] Cf. half-open file.
open game: A game in which exchanges have opened files and diagonals, and there are few pawns in the center, as opposed to a closed game.^[260]
Open Game: Any opening that begins with the moves 1.e4 e5. Examples of Open Games include the Ruy Lopez, the Giuoco Piano, the Danish Gambit, and many others. The Open Game is also referred to as a Double King's Pawn Opening or Double King's Pawn Game.
opening: The beginning phase of the game, roughly the first dozen moves, but it can extend much farther. In the opening players set up their pawn structures, develop their pieces, and usually castle. The opening precedes the middlegame.^[260]
opening innovation: A synonym for theoretical novelty.
opening preparation: Home study and analysis of openings and defenses that one expects to play, or meet, in later tournament or match games. In high-level play, an important part of this is the search for theoretical novelties that improve upon previous play or previously published analysis.^[261]
opening repertoire: The set of openings played by a particular player. The breadth of different players' repertoires varies from very narrow to very broad.^[262]
opening system: An opening that is defined by one player's moves and that can be played generally regardless of the moves of the opponent, with the goal of reaching a desired type of middlegame position. Sometimes several different move orders are possible. Examples include the Colle System and Hippopotamus Defense.^[263]
open lines: 1. n. Unobstructed files and diagonals. See also open game.; 2. v. To move or exchange pawns to bring about unobstructed files and diagonals.
open tournament: A tournament where anyone can enter, regardless of rating or invitation.^[264] Cf. closed tournament.
opposite castling: Or opposite-side castling. Describes when one player has castled kingside and the opponent has castled queenside.
opposite-colored bishops: See bishops on opposite colors.
opposition: A position in which two kings stand on the same rank, file, or diagonal with one empty square between them. The player to move may be forced to move the king to a less advantageous square. Opposition is a particularly important concept in endgames.^[265] One orthogonal square separation is direct opposition; one diagonal square is diagonal opposition; multiple squares separation is distant opposition. Cf. corresponding squares.
optimal play: See Best response. Both sides playing their best move at each turn, or one of equally good alternatives. One side tries to win as quickly as possible while the other side tries to delay it as long as possible, or optimal play may result in a draw. Cf. Solved game § Perfect play.
OTB: An abbreviation for over the board.^[266]
outpost: An outpost is a square protected by a pawn that is in or near the enemy's stronghold. Outposts are a favorable position from which one can launch an attack, particularly using a knight.^[267]
outside passed pawn: A passed pawn near the edge of the board and not in the path of threats from the opponent's pawns. In the endgame, such a pawn can constitute a strong advantage, because it threatens to promote, and it also diverts the opponent's forces to restrain its advance.^[268]
overextended: An overextended position results when a player has advanced pawns too far into the opponent's side without sufficient support. The premature advance can leave weaknesses in the player's camp or the advanced pawns themselves may be weak ("overextended pawns").^[269]
overloaded: A piece that has too many defensive duties. An overloaded piece can sometimes be deflected, or required to abandon one of its defensive duties.^[270]
overprotection: The strategy of protecting an important pawn or square more than is apparently necessary. This serves to dissuade the opponent from attacking that point, and the latent power of the "over protectors" assembled around an important point is a significant threat that can bear fruit at a small tactical change in the position. Aron Nimzowitsch coined the term and was a proponent of overprotection.^[271]
over the board: 1. An over-the-board game is played face to face with the opponent, as opposed to a remote opponent as in online chess or correspondence chess.; 2. Analysis carried out during a game in real time (not necessarily a face-to-face game) as opposed to during preparation. Finding accurate moves over the board is harder than finding them with computer assistance in one's own time. "I looked up the gambit Smith played and there's a line that refutes it, but I couldn't find it over the board."^[266]; Abbr. OTB.
overworked: See overloaded.^[272]

P

P: Symbol used for the pawn when recording chess positions in English; a lowercase p is typically used for a Black pawn. Also used for the pawn when recording chess moves in descriptive notation, e.g. P-K4.
pairing: The assignment of opponents in a tournament. The most common pairing methods used in chess tournaments are round-robin and the Swiss system.^[273]
passar battaglia: [from Italian, "to dodge the fight"] The former rule that a pawn could evade capture by an opposing pawn by its initial two-square advance, in contrast to the en passant rule. Passar battaglia remained the practice in several parts of Europe long after en passant was introduced, and it was not completely abandoned until 1880 when Italy adopted the en passant rule.^[274]
passed pawn: A pawn that has no pawn of the opposite color on its file or on an adjacent file to challenge or threaten its potential for queening.^[217]
passer: A passed pawn.^[275]
passive: Describes a piece or pawn that is inactive and able to move to or control relatively few squares, or a position without possibilities for attack or counterplay.^[271] Antonym: active.
passive sacrifice: The sacrifice of a piece, by moving a different piece, leaving the sacrificed piece under attack.
pattern recognition: A part of chess thinking that involves remembering and recognizing certain recurring positional aspects large and small, visual and dynamic. It is a kind of thinking that gives an advantage to a player with great experience. It is distinct from the intellectual activity of calculation. It uses intuitive thinking that is familiar to humans, but is foreign to computers. It can be developed by studying chess puzzles. It has been studied by Adriaan de Groot, and other scientists, who have attempted to discover how chess players think.^[276]^[277]
patzer: A weak chess player (from German: patzen, "to bungle").^[278] See also woodpusher.
pawn: A piece that can move one square directly forward, or on its first move, can move two squares directly forward. It can also move one square diagonally forward when capturing. It may capture en passant. Upon reaching its eighth rank, it is promoted to a same-colored queen, rook, bishop, or knight.
pawn and move: A type of odds game, common in the 18th and 19th centuries, in which the superior player plays Black and begins the game with one of their pawns, usually the king bishop pawn, removed from the board; plus White gets an extra move at the start.^[279]
pawn break: A pawn move that attacks an enemy pawn in order to open up lines and/or challenge the opponent's pawn structure. See also break.
pawn center: Or pawn centre. A player's pawns in the center of the board. Pawns on the squares adjacent to the center may also be considered part of the pawn center. Having a strong pawn center was considered absolutely essential until the hypermodernist school introduced some new ideas.^[280] Often shortened to center. See King's Indian Defense, Four Pawns Attack for an example of an opening leading to an extended pawn center.
pawn chain: Two or more pawns of the same color diagonally linked. A pawn chain's weakest point is the base because it is not protected by another pawn.^[271] See also pawn structure.
pawn island: A group of pawns of one color on consecutive files with no other pawns of the same color on an adjacent file. A pawn island consisting of one pawn is an isolated pawn.^[281]
pawn majority: See majority.
pawn minority: See minority.
pawn race: A situation where both opponents are pushing a passed pawn in effort to be first to promote.
pawn roller: Two connected passed pawns. "Roller" refers to their ability to defend one another as they advance toward promotion.
pawn skeleton: See pawn structure.
pawn storm: An attacking technique where a group of pawns on one wing is advanced to break up the defense.^[282]
pawn structure: The placement of the pawns during the course of a game. As pawns are the least mobile of the pieces and the only pieces unable to move backwards, the position of the pawns greatly influences the character of the game.^[283] Also called pawn skeleton.
PCA: An abbreviation for the Professional Chess Association.
performance rating: A number reflecting the approximate rating level at which a player performed in a particular tournament or match. It is often calculated by adding together the player's performances in each individual game, using the opponent's rating for a draw, adding 400 points to the opponent's rating for a win, and subtracting 400 points from the opponent's rating for a loss, then dividing by the total number of games. For example, a player who beat a 2400-rated player, lost to a 2600, drew a 2500, and beat a 2300, would have a performance rating of 2550 (i.e. 2800 + 2200 + 2500 + 2700, divided by 4).^[284] Abbr. PR.
perpetual check: Often shortened to perpetual. When a player puts the opponent in check and the check could be repeated endlessly, the game will be declared a draw by repetition. This tactic can be resorted to as a form of insurance in a losing position.^[285]
PGN: An abbreviation for Portable Game Notation.^[286]
Philidor position: Usually refers to an important chess endgame that illustrates a drawing technique when the defender has a king and rook versus a king, rook, and pawn. It is also known as the third rank defense, because of the importance of the rook on the third rank cutting off the opposing king. It was analyzed by Philidor in 1777.^[287] See also Rook and pawn versus rook endgame.
Philidor sacrifice: The sacrifice of a minor piece for one or two pawns for greater pawn mobility as compensation.^[288]
piece: 1. One of the chessmen or figures used to play the game – that is, a king, queen, rook, bishop, knight or pawn. Each piece type has its own rules of movement on the board and of capturing enemy pieces. This is the definition used in the context of rules of chess – for example, the touched piece rule.; 2. When annotating or discussing chess games, the term "piece" usually excludes pawns. It may be used collectively for all "non-pawns" – for example, "White's pieces are well-posted." In some contexts, it may refer specifically to a minor piece – for example, "White is up two pieces for a rook."^[289]
pin: When a piece is attacked but cannot legally move, because doing so would expose the player's own king to the attack; or when a piece is attacked and can legally move out of the line of attack, but such a move would expose a more valuable piece (or an unprotected piece) to capture.^[248] See absolute pin and relative pin, respectively.
playable: Said of an opening, a position, or move that gives the person playing it a tenable position.^[290]
play by hand: To make a move intuitively and without analyzing the move.^[291]
ply: Term mainly used in computer chess to denote one play of either White or Black. Thus equal to half a move.
poisoned pawn: An unprotected pawn that, if captured, causes positional problems or material loss.^[281]
Poisoned Pawn Variation: Any of several opening variations, the best-known of these being in the Najdorf Variation of the Sicilian Defense, in which there is a poisoned pawn.^[292]
Portable Game Notation: This is a popular computer-processible ASCII format for recording chess games (both the moves and related data).^[286] There are import and export versions: the import version is lax, while the export version is not. Abbr. PGN.
position: "The disposition of pieces and pawns, of one or both colours, at any stage of the game or as set in a composition."^[293] If one side has an overall advantage in strength, that side is said to have "the better position". If neither side has an overall advantage, the position might be called level or equal or balanced. The position of chessmen at the beginning of a game is called an array.^[294]
positional play: Play based on strategy, on gaining and exploiting small advantages, and on analyzing the larger position, rather than calculating the more immediate tactics.^[281] Cf. antipositional.
positional player: A player who specializes in positional play, as distinguished from a tactician.^{[citation needed]}
positional sacrifice: A sacrifice in which the lost material is not regained via a combination, but instead gains positional compensation. These typically require deep positional understanding and are often overlooked by computers^{[dubious – discuss]}. Also known as a true sacrifice, as opposed to a pseudo sacrifice or sham sacrifice.^{[citation needed]}
post mortem: Analysis of a game after it has concluded, typically by one or both players and sometimes with spectators (kibitzers) contributing as well. A player who has just lost the game thanks to a dubious move has the chance to "win the post-mortem" by finding a better one.^[281]
PR: An abbreviation for performance rating.
premove: In online chess, a move input that is made during the opponent's turn, to take effect only after the opponent has moved. Premoving, the act of making premoves, is a popular way of saving time in blitz and bullet formats.^[295]
preparation: See opening preparation.
prepared variation: A well-analyzed novelty in the opening that is not published but first used against an opponent in competitive play.^[296]
Principle of two weaknesses: A technique of increasing one's advantage by causing the opponent, who has one weakness, to have a second weakness. Even if both weaknesses are minor, the fact of having two, in practice, becomes a major weakness.^[297]
priyome: A Russian term for particular tactics that depend on pawn structure.^[298]
problem-like: An elegant and counterintuitive tactical shot, of the type generally found in chess problems rather than in actual play, can be termed problem-like.
promotion: Advancing a pawn to the eighth rank, converting it to a queen, rook, bishop, or knight. Promotion to a piece other than a queen is called underpromotion.^[248]
prophylaxis: A strategy that frustrates and protects against an opponent's plan or tactic for fear of the consequences.^[281] See also blockade, overprotection, and mysterious rook move.
protected passed pawn: A passed pawn that is supported by another pawn.^[299]
pseudo sacrifice: See sham sacrifice.
push: 1. v. To move a pawn forward.; 2. n. A pawn move forward.

queen knight: Or queen's knight. The knight that is on the queenside at the start of the game. Sometimes abbreviated "QN".^[83]
queen pawn: Or queen's pawn. A pawn on the queen's file, i.e. the d-file. Sometimes abbreviated "QP". Also queen rook pawn (QRP), queen knight pawn (QNP), and queen bishop pawn (QBP) for a pawn on the a-, b-, or c-file, respectively.^[83]
queen pawn opening: Or queen's pawn opening. An opening that begins 1.d4.
queen rook: Or queen's rook. The rook that is on the queenside at the start of the game. Sometimes abbreviated "QR".^[83]

raking bishops: Another term for Horwitz bishops.^[307]
randomized chess: "A form of unorthodox chess designed to discount knowledge of the openings. The pawns are placed as in the array and behind them the pieces are placed in unorthodox fashion."^[308] See also Fischerandom.
rank: A row of the chessboard. In algebraic notation, ranks are numbered 1–8 starting from White's side of the board; however, players customarily refer to ranks from their own perspectives. For example: White's king and other pieces start on their first (or "back" or "home") rank, whereas Black calls the same rank the "eighth" (or last) rank; White's seventh rank is Black's second; and so on. If neither perspective is given, White's view is assumed. This relative reference to ranks was formalized in the older descriptive notation.^[309]
rapid chess: A form of chess with reduced time limit, usually 30 minutes per player. Also called active chess and action chess.^[310]
rating: See Elo rating system.
recapture: The capture of an opponent's piece that previously made a capture, and usually played immediately following the opponent's capture move. The capture and recapture occur on the same square, and usually the pieces captured and recaptured have the same value.
refute: To demonstrate that a strategy, move, or opening is not as good as previously thought (often, that it leads to a loss), or that previously published analysis is unsound. A refutation is sometimes colloquially referred to as a bust. A refutation in the context of chess problems or endgame studies is often called a cook.^[311]
related squares: See corresponding squares.
relative pin: A pin where it is legal to move the pinned piece out of the line of attack. In other words, the piece is not pinned to the king, but to some other piece. Contrast with absolute pin where the pinned piece is not permitted to move, because the piece it is pinned to is the king.
remis: [from French] A draw. It literally means "reset" and is somewhat archaic (the usual word for a draw in modern French is nulle), but is internationally understood and may be used between players without a common language.
repertoire: See opening repertoire.
reserve tempo: A move a player has available. Such a move may not be crucial to the position on the board, but being able to force the opponent to move by making a reserve move can on occasion result in a significant advantage.^[312]
resign: To concede loss of the game. A resignation is usually indicated by stopping the clocks, sometimes by offering a handshake, or by saying "I resign". A traditional way to resign is by tipping over one's king. It is common for a game to be resigned, rather than for it to end with checkmate, because experienced players can foresee the checkmate.^[313]^[314] However, under FIDE Laws, a player's resignation results in a draw if there is no sequence of legal moves that could lead to their opponent checkmating them.^[315]
resign on time: A player who in a hopeless position intentionally runs out of time to avoid having to resign can be said to have resigned on time. This is usually performed in a more subtle manner than that of Curt von Bardeleben walking out of the tournament hall against Wilhelm Steinitz. A player low on time and in a losing position may simply "forget" to pay any attention to the clock.
reverse opening: See colors reversed.
Romantic chess: Romantic chess was the style of chess prevalent in the 19th century. It is characterized by bold attacks and sacrifices.^[316]
rook: A piece that may move along ranks and files without jumping.
rook lift: A maneuver that places a rook in front of its own pawns, often on the third or fourth rank. This can allow the rook to treat a half-open file as if it were an open file, or a closed file as if it were half-open.^[317]
rook pawn: Or rook's pawn. A pawn on the rook's file, i.e. the a-file or h-file. Sometimes abbreviated "RP".^[83]
round-robin tournament: This is a tournament in which each participant plays every other participant an equal number of times. In a double round-robin tournament the participants play each other exactly twice, once with white and once with black. A round robin tournament is commonly used if the number of participants is relatively small.^[318] See also Swiss tournament.
royal fork: A fork threatening the king and queen.^[319]
royal piece: A king or queen.^[83] In chess variants, the term refers to any piece that must be protected from capture; under this definition, only the king is royal in orthodox chess.

S

S: [from German: Springer, "jumper"] Alternative notation for the knight. Used rather than K, which means king.
sac: Short for sacrifice, usually used to describe a sacrifice for a mating attack.^[318]
sacrifice: A move or capture that voluntarily gives up material in return for an advantage such as space, development, or an attack. A sacrifice in the opening is called a gambit, especially when applied to a pawn.^[313]
SAN: An abbreviation for standard algebraic notation or short algebraic notation (e.g. 1.Nf3), as opposed to long algebraic notation (e.g. 1.Ng1-f3).

система: См. систему открывания .

Т

поведение: [от арабского: طبيعة ṭabīʕa, «сущность»] Также табия . В шахматных дебютах ключевым моментом является табия. Это может быть хорошо известная «отправная точка», где варианты разветвляются, это может быть позиция, которая достигается так часто, что настоящая игра начинается после этой начальной серии ходов по книге. ^[343]^[344]
основание стола: См. базу таблицы эндшпиля .
тактик: Игрок, специализирующийся на тактической игре, в отличие от позиционного игрока .

ТК: Аббревиатура для контроля времени .
ТД: Сокращение от имени директора турнира . ^[341]
техника: Способ, с помощью которого игрок превращает выгодную позицию в победу.
время: Единица времени, рассматриваемая как один ход. Игрок может увеличить темп в дебюте, если противник дважды перемещает одну и ту же фигуру. В эндшпиле можно захотеть потерять темп путем триангуляции , чтобы получить оппозицию . ^[338] Множественное число: темпы или темпи .
напряжение: Позиция, в которой возможен один или несколько разменов , например пара пешек, обращенных друг к другу по диагонали, где одна из них может взять другую, считается содержащей напряжение . Такая ситуация отличается от угрозы тем, что ее не нужно немедленно решать – например, если обе пешки защищены. Последствия разрешения напряжения должны постоянно учитываться обоими игроками на случай, если существует вероятность выигрыша или проигрыша материала . Это усложняет расчет лучшего хода , и поэтому возникает естественный соблазн «снять напряжение», совершив аналогичный размен (см. Упрощение ) или переместив атакуемую фигуру. «Сохранять напряжение» — значит избегать его разрешения, что может быть хорошим советом в зависимости от позиции.
перемещение текста: Этот термин используется в письменном анализе шахматных партий для обозначения хода, фактически сыгранного в игре, в отличие от других возможных ходов. Часто сокращается до text , например «Текст хуже, поскольку позволяет ...f5». Текстовые ходы обычно выделяются жирным шрифтом, тогда как аналитические ходы — нет.
тематический: Соответствует требованиям должности. Термин «тематический ход» часто применяется к ключевому ходу тематического плана. ^[346]
тематический турнир: Шахматный турнир , в котором каждая партия должна начинаться с определенного дебюта, указанного организаторами, например Будапештский гамбит (1.d4 Nf6 2.c4 e5).

время: 1. Количество времени, которое каждый игрок должен думать и считать, измеряется шахматными часами .; 2. Количество ходов для достижения цели; например, если король пытается помешать пешке превратиться в ферзя , а у короля слишком мало ходов, это можно назвать «недостаточно времени». ^[338] См. также темп .
контроль времени: Разрешенное время для игры обычно измеряется шахматными часами . Контроль времени может требовать либо выполнения определенного количества ходов за период времени (например, 40 ходов за 2 + 1 ⁄ блица часа) или может ограничить продолжительность всей игры (например, пять минут на партию для ) . Используются гибридные схемы, а средства управления задержкой стали популярными после широкого использования цифровых часов. ^[86]
задержка времени: Контроль времени , который позволяет игроку избежать постоянно уменьшающегося количества оставшегося времени (как в случае с внезапной смертью ). Наиболее важными временными задержками в шахматах являются задержка Бронштейна и задержка Фишера .

ТН: Аббревиатура для теоретической новизны .
верхняя доска: См. первую доску .
правило касания и перемещения: Или коснулся правила фигуры . Правило, требующее, чтобы игрок, коснувшийся фигуры, передвинул эту фигуру, если только у фигуры нет разрешенных ходов. Если игрок перемещает фигуру на определенное поле и убирает с нее руку, ход должен быть сделан на это поле, если это разрешенный ход. Рокировку необходимо начинать с перемещения короля первым, поэтому игроку, который касается своей ладьи, может потребоваться переместить ладью без рокировки. Правило также требует, чтобы игрок, коснувшийся фигуры противника, по возможности захватил ее. Чтобы изменить положение фигуры внутри ее клетки без необходимости ее перемещения, игрок должен сказать « J'adoube » или «Я поправляю». ^[348]
турнир: Соревнование, в котором участвуют более двух игроков или команд, обычно проводимое на одном месте (или на нескольких площадках) за относительно короткий период времени. Турнир разделен на раунды, каждый раунд состоит либо из отдельных игр, либо из матчей в случае турниров на выбывание и командных турниров. Распределение соперников называется жеребьёвкой , при этом наиболее популярными системами являются круговая система и швейцарская система .

Одним из хорошо известных примеров является Бронштейна международный шахматный турнир в Цюрихе 1953 года . Менее полный турнирный бюллетень обычно выпускается между раундами престижного мероприятия, предоставляя игрокам и мировым средствам массовой информации мгновенную запись игр предыдущего раунда. По завершении мероприятия отдельные экземпляры могут быть объединены в комплект, чтобы стать недорогой альтернативой турнирной книге. ^[350]

В

неясно: Позиция, в которой неясно, кто (если есть) имеет преимущество. ^[357]

победить: Победа одного из двух игроков в игре, которая может произойти из-за мата , сдачи другого игрока, превышения другим игроком контроля времени другого игрока или поражения директором турнира . Поскольку шахматы являются игрой с нулевой суммой , это приводит к проигрышу другого игрока. В турнире прощание может быть засчитано как победа. ^[366] См. также выигрышную позицию .
ветряная мельница: Комбинация , в которой две фигуры работают вместе, чтобы выполнить поочередную серию шахов и открытых шахов таким образом, что король противника должен двигаться на каждом ходу. Это мощный прием, поскольку при каждом втором ходе обнаруженный шах может позволить непроверяющей фигуре захватить вражескую фигуру без потери темпа . Самый известный пример — Торре-Ласкер, Москва, 1925 г. ^[367] Также называется качелями .
крыло: Вертикали фланга a, b и c ферзевого ; или королевского фланга. линии f, g и h ^[368] Также называется фланговым .
Фланговый гамбит: Название, данное вариантам нескольких дебютов, в которых один игрок делает гамбит фланговой пешки, обычно пешки b. ^[369]
процент выигрыша: Число, рассчитанное путем сложения количества выигранных игр и половины количества сыгранных вничью (т. е. без учета поражений), а затем деления этой суммы на общее количество сыгранных игр.Другой способ расчета процента выигрышей — взять процент выигранных игроком игр плюс половину процента ничьих. Таким образом, если из 100 игр игрок выигрывает 40 процентов, играет вничью 32 процента и проигрывает 28 процентов, то процент выигрышей составит 40 плюс половина от 32, т. е. 56 процентов. ^[370]

Х

рентген: Когда кажется, что сила фигуры, как атаковать, так и защититься, проходит через находящуюся рядом фигуру противника. Рентгеновская атака, также известная как вертел , происходит, когда две фигуры одного цвета попадают на одну и ту же линию атаки по диагонали, ряду или вертикали. Атакующая фигура заставляет первую и более ценную фигуру уйти с дороги, что позволяет захватить вторую фигуру. Рентгеновская защита возникает, когда одна фигура защищается другой фигурой через атакующую фигуру противника, стоящую между ними. ^[375]

С

цугцванг: [от немецкого «принуждение к движению»] Когда игрок оказывается в невыгодном положении из-за необходимости сделать ход; где любой законный шаг ослабляет позицию. Цугцванг обычно возникает в эндшпиле и редко в миттельшпиле . ^[378]
промежуточные шахматы: [от немецкого «промежуточный шах»] Проведение неожиданного шаха, который противник не учел при планировании последовательности ходов; zwischenzug — это проверка . ^[379]
промежуточный поезд: [от немецкого «промежуточный ход»] «Промежуточный» ход, или интермеццо, разыгрывается перед ожидаемым ответом. Часто, но не всегда, это включает в себя ответ на угрозу, создавая еще большую угрозу, вынуждая противника первым отреагировать на угрозу. ^[380]
