Extensive Definition

This page explains commonly used terms in chess in alphabetical order. Some of these have their own pages, like fork and pin. For a list of unorthodox chess pieces, see fairy chess piece; for a list of terms specific to chess problems, see chess problem terminology; for a list of chess related games, see chess variants.

A

Absolute pin

A pin against the king, called absolute because the pinned piece cannot legally move as it would expose the king to check. See relative pin.

Active

Describes a piece that is able to move or control many squares. See also passive.

Adjournment

Suspension of a chess game with the intention to continue at a later occasion. See Sealed move.

Adjudication

The process of a strong chess player deciding on the outcome of an unfinished game. This practice is now uncommon in over the board events, but does happen in online chess when one player refuses to continue after an adjournment.

Adjust or j'adoube

To adjust the position of a piece on its square without being required to move it. Adjustment can only be done when it is the player's move and the adjustment is preceded by saying "I adjust" or "j'adoube".

Advanced pawn

A pawn that is on the opponent's side of the board (the fifth rank or higher). 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 his mobility. An advanced passed pawn that threatens to promote can be especially strong.

Alekhine's gun

A formation in which a queen backs up two rooks on the same file.

Algebraic notation

The standard way to record a chess game using alphanumeric codes for the squares.

Amateur

A person who does not earn a living through chess. 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. 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.

Analysis

Breaking a position into iterations or most likely moves.

Annotation

Commentary on a game using a combination of written comments, chess symbols or notation.

Antipositional

A move or a plan that is not in accordance with the principles of positional play. 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.

Arbiter

A tournament official who arbitrates disputes and performs other duties such as keeping the score when players are under time pressure. See International Arbiter.

Armageddon

A game which White must win to win the match, but which Black only needs to draw to win the match.

Attack

An aggressive move or strategy. See defence.

Automaton

Bad bishop

A bishop which is hemmed in by the player's own pawns.

Critical position

A position that is of key importance in determining the soundness of an opening variation. If one side can demonstrate an advantage in a critical position, the other side must either find an improvement or else abandon that variation as inferior.

Cross-check

A cross-check is a check played in reply to a check, especially when the original check is blocked by a piece which itself either delivers check or reveals a discovered check from another piece.

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. The columns are also numbered, each one corresponding to the player in the same numbered row. Each table cell records the outcome of the game between the players on the intersecting row and column, 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.) Every game is recorded twice, once from the perspective of each player. The diagonal cells that correspond to the player playing himself are marked with a * or other symbol as they are not used. For examples see Hastings 1895 chess tournament, Nottingham 1936 chess tournament, and AVRO tournament.

  • A piece that seems determined to give itself up, typically either to bring about stalemate
  • A piece to sell itself as dearly as possible in a situation where both sides have hanging pieces.

Doubled pawns

A pair of pawns of the same color on the same file.

Doubled rooks

Two of a player's rooks placed on the same file or rank.

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 stalemate, threefold repetition, the fifty move rule, and insufficient material. A position is said to be a draw (or a drawn position) 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.

Drawing line

An opening variation that commonly ends in a draw, for example 1.e4 e5 2.Nf3 Nc6 3.Nc6 Nf6 4.Bb5 Nd4 5.Nxd4 exd4 6.e5 dxc3 7.exf6 Qxf6 8.dxc3 Qe5+ 9.Qe2 Qxe2+, a line in the Rubinstein Variation of the Four Knights Game. See Collection of drawing lines at chessgames.com. Often such a variation is played because one or both players is/are eager to draw the game.

Drawing weapon

An opening line that a player plays with the intent of drawing the game. This may or may not be a line commonly thought of as a drawing line. In high-level chess and correspondence chess, a player well-versed in opening theory may even use as a drawing weapon a sharp opening that has been analyzed to a drawn position in a number of lines, such as the Marshall Attack in the Ruy Lopez, and the Sveshnikov and Poisoned Pawn variations of the Sicilian Defense. One example of the successful employment of a drawing weapon was the 2000 World Chess Championship match between Garry Kasparov and Vladimir Kramnik. In that match, Kramnik used the Berlin Defense to the Ruy Lopez as a drawing weapon with great effect. Kramnik drew all four games with that opening, drew all the rest of his games as Black, and won two games as White, with no losses.

Duffer

A weak chess player, also referred to as a "fish", "patzer" or "woodpusher."

Dynamism

A style of play in which the activity of the pieces is favoured over more positional considerations, even to the point of accepting permanent structural or spatial weaknesses.

Exchange

  • The capture of a pair of pieces, one white and the other black, usually of the same type (i.e rook for rook, knight for knight etc).
  • The exchange is used to refer to the advantage of a rook over a minor piece (knight or bishop).

Heavy piece

A queen or rook, also known as a major piece.

Hole

A square that a player does not, and cannot in future, control with a friendly pawn. The definition is somewhat subjective: the square must have some positional significance for the opponent to be considered a hole - squares on the first and second ranks are not holes. On the other hand a square is a hole even if it can be controlled in the future with a pawn that has made a capture. An example of the hole is the square e4 in the Stonewall Attack.

Indian bishop

A fianchettoed bishop, characteristic of the Indian defences, the King's Indian and the Queen's Indian.

Indian defence

A chess opening that begins 1.d4 Nf6. Originally used to describe queen's pawn defences involving the fianchetto of one or both Black bishops, it is now used to describe all Black defences after 1.d4 Nf6 that do not transpose into the Queen's Gambit.

Insufficient material

An endgame scenario in which all pawns have been captured, and one side has only its king remaining while the other is down to just a king or a king plus one knight or one bishop. A king and bishop versus a king and bishop with the bishops on the same color is also a draw. The position is a draw because it is impossible for the dominant side to deliver checkmate regardless of play. Situations where checkmate is possible only if the inferior side blunders are covered by the fifty move rule. (See Draw (chess)#Draws in all games.)

Isolated pawn

A pawn with no pawn of the same color on an adjacent file.

Italian bishop

Staunton chessmen

The standard design of chess pieces, required for use in competition.

Stem game

A stem game is the chess game featuring the first use of a particular opening variation. Sometimes, the player or the venue of the stem game is then used to refer to that opening.

Sudden death

The most straightforward time control for a chess game: each player has a fixed amount of time available to make all moves.

Swindle

A ruse by which a player in a losing position tricks his opponent, and thereby achieves a win or draw instead of the expected loss. It may also refer more generally to achieving a win or draw from a clearly losing position. See also cheapo.

Swiss tournament

This is a tournament that uses the Swiss system to determine player pairings. The basic idea is that every round each player is paired with an opponent with the same (or close to the same) score. The 33rd Chess Olympiad is an example of a Swiss tournament. See also Round-robin tournament.

T

Tabia or Tabiya

(from Arabic)
  1. The initial position of the pieces in Shatranj
  2. The final position of a well-known chess opening
  3. (from 2) The opening position from which two players familiar with each others' tastes begin play.

Tablebase

See Endgame tablebase.

Tactician

A player who specializes in tactical play, as distinguished from a "positional player."

Tactics

Play characterized by short-term attacks and threats, often requiring extensive calculation by the players, as distinguished from positional play.

Takeback

Used in casual games when both players agree to undo one or more moves.

Tarrasch rule

Named after Siegbert Tarrasch, this refers to the general principle that rooks should be placed behind passed pawns.

Tempo

An extra move, an initiative at development. A player gains a tempo (usually in the opening) by making the opponent move the same piece twice or defend an enemy piece. In the endgame, one may wish to lose a tempo by triangulation to gain against the opposition. (Plural: tempos or tempi).

Text move

This term is used in written analysis of chess games to refer to a move that has been played in the game as opposed to other possible moves. Text moves are usually in bold whereas analysis moves are not.

Theoretical Novelty (TN)

A new move in the opening. Also called simply a "novelty."

Threat

A plan or move that, if left unattended, would result in an immediate depreciation of the opponents position.

Threefold repetition

A draw may be claimed if the same position occurs three times with the same player to move, and with each player having the same set of legal moves each time (the latter includes the right to take en passant and the right to castle).

Tiebreaks

This refers to a number of different systems that are used to break ties, and thus designate a single winner, where multiple players or teams tie for the same place in a Swiss system chess tournament.

Time

Opportunities to make moves: similar meaning to tempo. A move that does not alter the position significantly is described as "wasting time", and forcing the other player to waste time is described as "gaining time".

Time control

The allowed time to finish a game, usually measured by a chess clock. A time control can require either a certain number of moves be made per time period (e.g., 40 moves in 2½ hours) or it can limit the length of the entire game (e.g., 5 minutes per game for blitz). Hybrid schemes are used, and time delay controls have become popular since the widespread use of digital clocks.

Time delay

A time control which makes it possible for a player to avoid having an ever-decreasing amount of time remaining (as is the case with sudden death). The most important time delays in chess are Bronstein delay and Fischer delay.

Time pressure or time trouble

Having very little time on one's clock (especially less than five minutes) to complete one's remaining moves. See Time control.

Toilet move

Coined by Nigel Short, a quickly played move described as "any move which doesn't immediately jeopardise your position" allowing the player time to visit the toilet while his opponent thinks.

Top board

In team chess, the player who is assigned to face the strongest opponents. Also called first board. Second board faces the next strongest players, followed by third board, and so on. Generally board assignments must be made before the competition begins and players may not switch boards, although reserve players are often allowed as substitutes.

Touched piece rule

The rule requiring a player who touches a piece that has at least one legal move to move that piece (and, if the player moves the piece to a particular square and takes his hand off it, to move it to that square). Castling must be initiated by moving the king first, so a player who touches his rook may be required to move it, without castling. The rule also requires a player who touches an opponent's piece to capture it if possible. A player wishing to touch a piece to adjust its position on a square without being required to move it signals this intent by saying "J'adoube" or "I adjust". This way of playing is common in official games, in favour of clock move.

Tournament

A competition involving more than two players or teams, generally played at a single venue (or series of venues) in a relatively short period of time. A tournament is divided into rounds, with each round consisting either of individual games or matches in the case of knockout tournaments and team tournaments. The assignment of opponents is called pairing, with the most popular systems being round-robin and Swiss. Tournaments are usually referred to by combining the city in which they were played with the year, as in London 1851, although there are well known exceptions such as AVRO.

Tournament book

A book recording the scores of all the games in a tournament, usually with analysis of the best or most important games and some background on the event and its participants. One well-known example is Bronstein's Zurich International Chess Tournament 1953.

Tournament director (TD)

Organizer and arbiter of a tournament, responsible for enforcing the tournament rules and the Laws of Chess. Also tournament controller (chiefly British).

Transposition

Arriving at a position using a different sequence of moves.

Trap

A move which may tempt the opponent to play a losing move. See also Swindle.

Trébuchet

a position of mutual zugzwang in which either player would lose if it is his turn to move.

Triangulation

A technique used in king and pawn endgames (less commonly seen with other pieces) to lose a tempo and gain the opposition.

U

Undermining

This is a chess tactic (also known as removal of the guard) in which a defensive piece is captured, leaving one of the opponent's pieces undefended or underdefended.

Underpromotion

Promoting a pawn to a rook, bishop, or knight instead of a queen. Rarely seen unless the knight can deliver a crucial check, or promotion to a rook instead of a queen is necessary to avoid stalemate.

Unpinning

the act of breaking a pin. This allows the piece that was formerly pinned to move.

United States Chess Federation (USCF)

This is a non-profit organization, the governing chess organization within the United States, and one of the federations of the FIDE.

Unorthodox opening

See Irregular opening.

V

Vacating sacrifice

A sacrifice made for the purpose of clearing a square for a different piece of the same color.

Valve

A move which opens one line and closes another.

Variant

A chess-like game played using a different board, pieces, or rules than standard chess.

Variation

A sequence of moves or alternative line of play, often applied to the opening. A variation does not have to have been played in a game, it may also be a possibility that occurs only in analysis. The word Variation is also used to name specific sequences of moves within an opening. For an example, the Dragon Variation is part of the Sicilian Defence.

W

Waiting move

A passive but harmless move, which is played while waiting for initiative from the opponent.

Weak square

A square that cannot be easily defended from attack by an opponent. Often a weak square is unable to be defended by pawns (a hole) and can be theoretically occupied by a piece. Exchange or loss of a bishop may make all squares of that bishop's color weak resulting in a "weak square complex" on the light squares or the dark squares.

WFM

Abbreviation for the Woman FIDE Master title.

WGM

Abbreviation for the Woman Grandmaster title.

White

The designation for the player who moves first, even though the corresponding pieces, referred to as "the white pieces," are sometimes actually some other (usually light) color. See also Black, First move advantage in chess.

WIM

Abbreviation for the Woman International Master title.

Win

A victory for one of the two players in a game, which may occur due to checkmate, resignation by the other player, the other player exceeding the time control, or the other player being forfeited by the tournament director. Chess being a zero-sum game, this results in a loss for the other player.

Win/winning position

A position is said to be a win (or a winning position) if one specified side, with correct play, can eventually force a checkmate against any defence (i.e. perfect defence).

Windmill

A combination in which two pieces work together to deliver an alternating series of checks and discovered checks in such a way that the opposing king is required to move on each turn. It is a potent technique since on every other move, the discovered check may allow the non-checking piece to capture an enemy piece without losing a tempo. The most famous example is Torre–Lasker, Moscow 1925. Also called a see-saw.

Wing

The queenside a, b, and c-files, or the kingside f, g, and h-files, also called flank.

Wing Gambit

Is the name given to the branches of several openings in which one player gambits a wing pawn, usually the b pawn.
