[PREFACE]The Laws of Chess cannot cover all possible situations that may arise during a game, nor can they regulate all administrative questions. Where cases are not precisely regulated by an Article of the Laws, it should be possible to reach a correct decision by studying analogous situations which are discussed in the Laws. The Laws assume that arbiters have the necessary competence, sound judgement and absolute objectivity. Too detailed a rule might deprive the arbiter of his freedom of judgement and thus prevent him from finding the solution to a problem dictated by fairness, logic and special factors. |
FIDE appeals to all chess players and federations to accept this view. |
[ITEMIZE]A member federation is free to introduce more detailed rules provided they: |
[ITEM]a. do not conflict in any way with the official FIDE Laws of Chess, and[\ITEM] |
[ITEM]b. are limited to the territory of the federation concerned, and[\ITEM] |
[ITEM]c. are not valid for any FIDE match, championship or qualifying event, or for a FIDE title or rating tournament.[\ITEM][\ITEMIZE][\PREFACE] |
[ARTICLE1] The nature and objectives of the game of chess |
[ARTCILE1.1]The game of chess is played between two opponents who move their pieces alternately on a square board called a ‘chessboard’. The player with the white pieces commences the game. A player is said to ‘have the move’, when his opponent’s move has been ‘made’. (See Article 6.7)[\ARTCILE1.1] |
[ARTICLE1.2]The objective of each player is to place the opponent’s king ‘under attack’ in such a way that the opponent has no legal move. The player who achieves this goal is said to have ‘checkmated’ the opponent’s king and to have won the game. Leaving one’s own king under attack, exposing one’s own king to attack and also ’capturing’ the opponent’s king are not allowed. The opponent whose king has been checkmated has lost the game.[\ARTICLE1.2] |
[ARTICLE1.3]If the position is such that neither player can possibly checkmate, the game is drawn.[\ARTICLE1.3][\ARTICLE1] |
[ARTICLE2]The initial position of the pieces on the chessboard |
[ARTICLE2.1]The chessboard is composed of an 8 x 8 grid of 64 equal squares alternately light (the ‘white’ squares) and dark (the ‘black’ squares). The chessboard is placed between the players in such a way that the near corner square to the right of the player is white.[\ARTICLE2.1] |
[ARTICLE2.2]At the beginning of the game one player has 16 light-coloured pieces (the ‘white’ pieces);the other has 16 dark-coloured pieces (the ‘black’ pieces).These pieces are as follows: A white king ,A white queen ,Two white rooks ,Two white bishops ,Two white knights ,Eight white pawns,A black king ,A black queen ,Two black rooks ,Two black bishops ,Two black knights ,Eight black pawns [\ARTICLE2.2] |
[ARTICLE2.3]The setup is universal to all standard chess games, positioning the pieces in their starting locations before the game begins: The first row (closest to the player): rook, knight, bishop, queen, king, bishop, knight, and rook. The second row: all pawns.[\ARTICLE2.3] |
[ARTICLE2.4]The eight vertical columns of squares are called ‘files’. The eight horizontal rows of squares are called ‘ranks’. A straight line of squares of the same colour, running from one edge of the board to an adjacent edge, is called a ‘diagonal’.[\ARTICLE2.4][\ARTICLE2] |
[ARTICLE3] The moves of the pieces |
[ARTICLE3.1]It is not permitted to move a piece to a square occupied by a piece of the same colour. If a piece moves to a square occupied by an opponent’s piece the latter is captured and removed from the chessboard as part of the same move. A piece is said to attack an opponent’s piece if the piece could make a capture on that square according to the Articles 3.2 to 3.8. |
A piece is considered to attack a square, even if such a piece is constrained from moving to that square because it would then leave or place the king of its own colour under attack.[\ARTICLE3.1] |
[ARTICLE3.2]The bishop may move to any square along a diagonal on which it stands.[\ARTICLE3.2] |
[ARTICLE3.3]The rook may move to any square along the file or the rank on which it stands.[\ARTICLE3.3] |
[ARTICLE3.4]The queen may move to any square along the file, the rank or a diagonal on which it stands.[\ARTICLE3.4] |
[ARTICLE3.5]When making these moves the bishop, rook or queen may not move over any intervening pieces.[\ARTICLE3.5] |
[ARTICLE3.6]The knight may move to one of the squares nearest to that on which it stands but not on the same rank, file or diagonal.[\ARTICLE3.6] |
[ARTICLE3.7][ITEMIZE][ITEM]a. The pawn may move forward to the unoccupied square immediately in front of it on the same file, or[\ITEM] |
[ITEM]b. on its first move the pawn may move as in 3.7.a or alternatively it may advance two squares along the same file provided both squares are unoccupied, or[\ITEM] |
[ITEM]c. the pawn may move to a square occupied by an opponent’s piece, which is diagonally in front of it on an adjacent file, capturing that piece.[\ITEM] |
[ITEM]d. A pawn attacking a square crossed by an opponent’s pawn which has advanced two |
squares in one move from its original square may capture this opponent’s pawn as |
though the latter had been moved only one square. This capture is only legal on the |
move following this advance and is called an ‘en passant’ capture.[\ITEM] |
e. When a pawn reaches the rank furthest from its starting position it must be exchanged as part of the same move on the same square for a new queen, rook, bishop or knight of the same colour. The player’s choice is not restricted to pieces that have been captured previously. This exchange of a pawn for another piece is called ‘promotion’ and the effect of the new piece is immediate.[\ITEM][\ITEMIZE][\ARTICLE3.7] |
[ARTICLE3.8][ITEMIZE][ITEM]a. There are two different ways of moving the king: by moving to any adjoining square not attacked by one or more of the opponent’s piecesor by ‘castling’. This is a move of the king and either rook of the same colour along the player’s first rank, counting as a single move of the king and executed as follows: the king is transferred from its original square two squares towards the rook on its original square, then that rook is transferred to the square the king has just crossed.[\ITEM] |
[ITEM]b. [ITEMIZE][ITEM](1) The right to castle has been lost: (a) if the king has already moved, or (b) with a rook that has already moved.[\ITEM] |
[ITEM](2) Castling is prevented temporarily: (a) if the square on which the king stands, or the square which it must cross, or the square which it is to occupy, is attacked by one or more of the opponent's pieces, or (b) if there is any piece between the king and the rook with which castling is to be effected.[\ITEM][\ITEMIZE][\ITEM][\ITEMIZE] |
[\ARTICLE3.8] |
[ARTICLE3.9]The king is said to be 'in check' if it is attacked by one or more of the opponent's pieces, even if such pieces are constrained from moving to that square because they would then leave or place their own king in check. No piece can be moved that will either expose the king of the same colour to check or leave that king in check.[\ARTICLE3.9][\ARTICLE3] |
[ARTICLE4]The act of moving the pieces |
[ARTICLE4.1]Each move must be made with one hand only.[\ARTICLE4.1] |
[ARTICLE4.2]Provided that he first expresses his intention (for example by saying „j’adoube“ or “I adjust”), the player having the move may adjust one or more pieces on their squares.[\ARTICLE4.2] |
[ARTICLE4.3][ITEMIZE]Except as provided in Article 4.2, if the player having the move deliberately touches on the chessboard: |
[ITEM]a. one or more of his own pieces, he must move the first piece touched which can be |
moved[\ITEM] |
[ITEM]one or more of his opponent’s pieces, he must capture the first piece touched which can be captured[\ITEM] |
[ITEM]one piece of each colour, he must capture the opponent’s piece with his piece or, if this is illegal, move or capture the first piece touched which can be moved or captured. If it is unclear, whether the player’s own piece or his opponent’s was touched first, the player’s own piece shall be considered to have been touched before his opponent’s.[\ITEM][\ITEMIZE][\ARTICLE4.3] |
[ARTICLE4.4][ITEMIZE]If a player having the move: |
[ITEM]a. deliberately touches his king and rook he must castle on that side if it is legal to doso[\ITEM] |
[ITEM]b. deliberately touches a rook and then his king he is not allowed to castle on that side on that move and the situation shall be governed by Article 4.3.a[\ITEM] |
[ITEM]c. intending to castle, touches the king or king and rook at the same time, but castling on that side is illegal, the player must make another legal move with his king (which may include castling on the other side). If the king has no legal move, the player is free to make any legal move[\ITEM] |
[ITEM]promotes a pawn, the choice of the piece is finalised, when the piece has touched the square of promotion.[\ITEM][\ITEMIZE][\ARTICLE4.4] |
[ARTICLE4.5]If none of the pieces touched can be moved or captured, the player may make any legal move.[\ARTICLE4.5] |
[ARTICLE4.6][ITEMIZE]When, as a legal move or part of a legal move, a piece has been released on a square, it cannot be moved to another square on this move. The move is then considered to have been made: |
[ITEM]a. in the case of a capture, when the captured piece has been removed from the chessboard and the player, having placed his own piece on its new square, has released this capturing piece from his hand[\ITEM] |
[ITEM]b. in the case of castling, when the player's hand has released the rook on the square previously crossed by the king. When the player has released the king from his hand, the move is not yet made, but the player no longer has the right to make any move other than castling on that side, if this is legal[\ITEM] |
[ITEM]c. in the case of the promotion of a pawn, when the pawn has been removed from the chessboard and the player's hand has released the new piece after placing it on the promotion square. If the player has released from his hand the pawn that has reached the promotion square, the move is not yet made, but the player no longer has the right to play the pawn to another square.[\ITEM][\ITEMIZE] |
The move is called legal when all the relevant requirements of Article 3 have been fulfilled. If the move is not legal, another move shall be made instead as per Article 4.5.[\ARTICLE4.6] |
[ARTICLE4.7]A player forfeits his right to a claim against his opponent’s violation of Article 4 once he deliberately touches a piece.[\ARTICLE4.7][\ARTICLE4] |
[ARTICLE5]The completion of the game |
[ARTICLE5.1][ITEMIZE][ITEM]a. The game is won by the player who has checkmated his opponent’s king. This immediately ends the game, provided that the move producing the checkmate position was a legal move.[\ITEM] |
[ITEM]The game is won by the player whose opponent declares he resigns. This immediately ends the game.[\ITEM][\ITEMIZE][\ARTICLE5.1] |
[ARTICLE5.2][ITEMIZE][ITEM]a. The game is drawn when the player to move has no legal move and his king is not in check. The game is said to end in ‘stalemate’. This immediately ends the game, provided that the move producing the stalemate position was legal.[\ITEM] |
[ITEM]b. The game is drawn when a position has arisen in which neither player can checkmate the opponent’s king with any series of legal moves. The game is said to end in a ‘dead position’. This immediately ends the game, provided that the move producing the position was legal. (See Article 9.6)[\ITEM] |
[ITEM]c. The game is drawn upon agreement between the two players during the game. This immediately ends the game. (See Article 9.1)[\ITEM] |
[ITEM]d. The game may be drawn if any identical position is about to appear or has appeared on the chessboard at least three times. (See Article 9.2)[\ITEM] |
[ITEM]e. The game may be drawn if each player has made at least the last 50 consecutive moves without the movement of any pawn and without any capture. (See Article9.3)[\ITEM][\ITEMIZE][\ARTICLE5.2][\ARTICLE5] |
[ARTICLE6]The chess clock |
[ARTICLE6.1]Chess clock’ means a clock with two time displays, connected to each other in such a way that only one of them can run at one time. ‘Clock’ in the Laws of Chess, means one of the two time displays. Each time display has a ‘flag’. ‘Flag fall’ means the expiration of the allotted time for a player.[\ARTICLE6.1] |
[ARTICLE6.2][ITEMIZE][ITEM]a. When using a chess clock, each player must make a minimum number of moves or all moves in an allotted period of time and/or may be allocated an additional amount of time with each move. All these must be specified in advance.[\ITEM] |
[ITEM]b. The time saved by a player during one period is added to his time available for the next period, except in the ‘time delay’ mode. In the time delay mode both players receive an allotted ‘main thinking time’. Each player also receives a ‘fixed extra time’ with every move. The countdown of the main time only commences after the fixed time has expired. Provided the player stops his clock before the expiration of the fixed time, the main thinking time does not change, irrespective of the proportion of the fixed time used.[\ITEM][\ITEMIZE][\ARTICLE6.2] |
[ARTICLE6.3]Immediately after a flag falls, the requirements of article 6.2 a. must be checked.[\ARTICLE6.3] |
[ARTICLE6.4]Before the start of the game the arbiter decides where the chess clock is placed.[\ARTICLE6.4] |
[ARTICLE6.5]At the time determined for the start of the game the clock of the player who has the white pieces is started.[\ARTICLE6.5] |
[ARTICLE6.6][ITEMIZE][ITEM]a. Any player who arrives at the chessboard after the start of the session shall lose the game. Thus the default time is 0 minutes. The rules of a competition may specify otherwise.[\ITEM] |
[ITEM]b. If the rules of a competition specify a different default time, the following shall apply. If neither player is present initially, the player who has the white pieces shall lose all the time that elapses until he arrives, unless the rules of the competition specify or the arbiter decides otherwise.[\ITEM][\ITEMIZE][\ARTICLE6.6] |
[ARTICLE6.7][ITEMIZE][ITEM]a. During the game each player, having made his move on the chessboard, shall stop his own clock and start his opponent’s clock. A player must always be allowed to stop his clock. His move is not considered to have been completed until he has done so, unless the move that was made ends the game. (See the Articles 5.1.a, 5.2.a, 5.2.b, 5.2.c and 9.6) The time between making the move on the chessboard and stopping his own clock and starting his opponent‘s clock is regarded as part of the time allotted to the player.[\ITEM] |
[ITEM]b. A player must stop his clock with the same hand as that with which he made his move. It is forbidden for a player to keep his finger on the button or to ‘hover’ over it.[\ITEM] |
[ITEM]c. The players must handle the chess clock properly. It is forbidden to punch it forcibly, to pick it up or to knock it over. Improper clock handling shall be penalised in accordance with Article 13.4.[\ITEM] |
[ITEM]d. If a player is unable to use the clock, an assistant, who must be acceptable to the arbiter, may be provided by the player to perform this operation. His clock shall be adjusted by the arbiter in an equitable way.[\ITEM][\ITEMIZE][\ARTICLE6.7] |
[ARTICLE6.8]A flag is considered to have fallen when the arbiter observes the fact or when either player has made a valid claim to that effect.[\ARTICLE6.8] |
[ARTICLE6.9]Except where one of the Articles: 5.1.a, 5.1.b, 5.2.a, 5.2.b, 5.2.c applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by the player. However, the game is drawn, if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves.[\ARTICLE6.9] |
[ARTICLE6.10][ITEMIZE][ITEM]a. Every indication given by the clocks is considered to be conclusive in the absence of any evident defect. A chess clock with an evident defect shall be replaced. The arbiter shall replace the clock and use his best judgment when determining the times to be shown on the replacement chess clocks.[\ITEM] |
[ITEM]b. If during a game it is found that the setting of either or both clocks was incorrect, either player or the arbiter shall stop the clocks immediately. The arbiter shall install the correct setting and adjust the times and move counter. He shall use his best judgement when determining the correct settings.[\ITEM][\ITEMIZE][\ARTICLE6.10] |
[ARTICLE6.11]If both flags have fallen and it is impossible to establish which flag fell first then:[ITEMIZE] |
[ITEM]a. the game shall continue if it happens in any period of the game except the last period[\ITEM] |
[ITEM]b. the game is drawn if it happens in the period of a game, in which all remaining moves must be completed.[\ITEM][\ITEMIZE][\ARTICLE6.11] |
[ARTICLE6.12][ITEMIZE][ITEM]a. If the game needs to be interrupted, the arbiter shall stop the clocks.[\ITEM] |
[ITEM]b. A player may stop the clocks only in order to seek the arbiter’s assistance, for example when promotion has taken place and the piece required is not available.[\ITEM] |
[ITEM]c. The arbiter shall decide when the game is to be restarted in either case.[\ITEM] |
[ITEM]d. If a player stops the clocks in order to seek the arbiter’s assistance, the arbiter shall determine if the player had any valid reason for doing so. If it is obvious that the player had no valid reason for stopping the clocks, the player shall be penalised according to Article 13.4.[\ITEM][\ITEMIZE][\ARTICLE6.12] |
[ARTICLE6.13]If an irregularity occurs and/or the pieces have to be restored to a previous position, the arbiter shall use his best judgement to determine the times to be shown on the clocks. He shall also, if necessary, adjust the clock’s move counter.[\ARTICLE6.13] |
[ARTICLE6.14]Screens, monitors, or demonstration boards showing the current position on the chessboard, the moves and the number of moves made, and clocks which also show the number of moves, are allowed in the playing hall. However, the player may not make a claim relying solely on information shown in this manner.[\ARTICLE6.14][\ARTICLE6] |
