FIDE Laws of Chess
|
The FIDE Laws of Chess cover over-the-board
play.
The English text is the authentic version of the Laws
of Chess, which was adopted at the 71st FIDE Congress at Istanbul (Turkey)
November 2000, coming into force on 1 July 2001.
In these Laws the words 'he', 'him' and 'his' include
'she' and 'her'. |
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.
A member federation is free to introduce more detailed
rules provided they:
- do not conflict in any way with the official FIDE Laws of Chess
- are limited to the territory of the federation in question; and
- are not valid for any FIDE match, championship or qualifying event, or
for a FIDE title or rating tournament.

RULES OF PLAY |
Article 1: The nature and objectives of the
game of chess |
1.1 |
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. |
1.2 |
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 which
would avoid the 'capture' of the king on the following move. The player who
achieves this goal is said to have 'checkmated' the opponent's king and to
have won the game. The opponent whose king has been checkmated has lost the
game. |
1.3 |
If the position is such that neither player can possibly
checkmate, the game is drawn. |
Article 2: The initial position of the
pieces on the chessboard |
2.1 |
The chessboard is composed of an 8x8 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. |
2.2 |
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, usually indicated by the symbol |
|
A white queen, usually indicated by the symbol |
|
Two white rooks, usually indicated by the symbol |
|
Two white bishops, usually indicated by the symbol |
|
Two white knights, usually indicated by the symbol |
|
Eight white pawns, usually indicated by the symbol |
|
A black king, usually indicated by the symbol |
|
A black queen, usually indicated by the symbol |
|
Two black rooks, usually indicated by the symbol |
|
Two black bishops, usually indicated by the symbol |
|
Two black knights, usually indicated by the symbol |
|
Eight black pawns, usually indicated by the symbol |
|
|
2.3 |
The initial position of the pieces on the chessboard is
as follows:
|
2.4 |
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, touching corner to corner, is called a
'diagonal'. |
Article 3: The moves of the pieces |
3.1 |
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 Articles 3.2 to 3.8.
|
3.2 |
The bishop may move to any square along a diagonal on
which it stands.
|
3.3 |
The rook may move to any square along the file or the
rank on which it stands.
|
3.4 |
The queen may move to any square along the file, the rank
or a diagonal on which it stands.
|
3.5 |
When making these moves the bishop, rook or queen may not
move over any intervening pieces. |
3.6 |
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.
|
3.7 |
-
The pawn may move forward to the unoccupied square
immediately in front of it on the same file, or
-
on its first move the pawn may move as in (a);
alternatively it may advance two squares along the same file provided both
squares are unoccupied, or
-
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.
-
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 may only be made on the move following this advance
and is called an 'en passant' capture.
-
When a pawn reaches the rank furthest from its starting
position it must be exchanged as part of the same move for a 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.
|
3.8 |
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 pieces.
The opponent's pieces are considered to attack a
square, even if such pieces cannot themselves move.
or
-
'castling'. This is a move of the king and either rook
of the same colour on the same 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, then that rook is transferred to the square
the king has just crossed.
(1) Castling is illegal:
-
if the king has already moved, or
-
with a rook that has already moved
(2) Castling is prevented temporarily
-
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.
-
if there is any piece between the king and the rook
with which castling is to be effected.
b. 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 cannot themselves move.
Declaring a check is not obligatory. |
3.9 |
No piece can be moved that will expose its own king to
check or leave its own king in check. |
Article 4: The act of moving the pieces
|
4.1 |
Each move must be made with one hand only. |
4.2 |
Provided that he first expresses his intention (e.g. by
saying "j'adoube" or "I adjust"), the player having the move may adjust one
or more pieces on their squares. |
4.3 |
Except as provided in Article 4.2, if the player having
the move deliberately touches on the chessboard
-
one or more of his own pieces, he must move the first
piece touched that can be moved, or
-
one or more of his opponent's pieces, he must capture
the first piece touched, which can be captured, or
-
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.
|
4.4 |
-
If a player deliberately touches his king and rook he
must castle on that side if it is legal to do so.
-
If a player 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).
-
If a player, 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.
|
4.5 |
If none of the pieces touched can be moved or captured,
the player may make any legal move. |
4.6 |
A player forfeits his right to a claim against his
opponent's violation of Article 4.3 or 4.4, once he deliberately touches a
piece. |
4.7 |
When, as a legal move or part of a legal move, a piece
has been released on a square, it cannot then be moved to another square.
The move is considered to have been made when all the relevant requirements
of Article 3 have been fulfilled. |
Article 5: The completion of the game
|
5.1 |
-
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.
-
The game is won by the player whose opponent declares
he resigns. This immediately ends the game.
|
5.2 |
-
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.
-
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.
-
The game is drawn upon agreement between the two
players during the game. This immediately ends the game. (See Article 9.1)
-
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)
-
The game may be drawn if each player has made the last
50 consecutive moves without the movement of any pawn and without the
capture of any piece. (See Article 9.3)
|
COMPETITION RULES |
Article 6: The chess clock |
6.1 |
'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.
'Flag fall' means the expiration of the allotted time for a player. |
6.2 |
-
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.
-
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.
|
6.3 |
Each time display has a 'flag'. Immediately after a flag
falls, the requirements of Article 6.2(a) must be checked. |
6.4 |
Before the start of the game the arbiter decides where
the chess clock is placed. |
6.5 |
At the time determined for the start of the game the
clock of the player who has the white pieces is started. |
6.6 |
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.. |
6.7 |
Any player who arrives at the chessboard more than one
hour after the scheduled start of the session shall lose the game unless the
rules of the competition specify or the arbiter decides otherwise. |
6.8 |
-
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 Articles 5.1, and 5.2)
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.
-
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.
-
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.
-
If a player is unable to use the clock, an assistant,
who is acceptable to the arbiter, may be provided by the player to perform
this operation. The clocks shall be adjusted by the arbiter in an
equitable way.
|
6.9 |
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. |
6.10 |
Except where Articles 5.1 or one of the Articles 5.2 (a),
(b) and (c) apply, 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, even with the most
unskilled counterplay. |
6.11 |
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 use his best judgement
when determining the times to be shown on the replacement chess clock. |
6.12 |
If both flags have fallen and it is impossible to
establish which flag fell first, the game shall continue. |
6.13 |
-
If the game needs to be interrupted, the arbiter shall
stop the clocks.
-
A player may stop the clocks only in order to seek the
arbiter's assistance, for instance when promotion has taken place and the
piece required is not available.
-
The arbiter shall decide when the game is to be
restarted in either case.
-
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 has no valid
reason for stopping the clocks, the player shall be penalised according to
article 13.4.
|
6.14 |
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. |
6.15 |
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 based on information shown in
this manner. |
Article 7: Irregularities |
7.1 |
-
If during a game it is found that the initial position
of the pieces was incorrect, the game shall be cancelled and a new game
played.
-
If during a game it is found that the only error is
that the chessboard has been placed contrary to Article 2.1, the game
continues but the position reached must be transferred to a correctly
placed chessboard.
|
7.2 |
If a game has begun with colours reversed, then it shall
continue, unless the arbiter rules otherwise. |
7.3 |
If a player displaces one or more pieces, he shall
re-establish the correct position on his own time. If necessary, either the
player or his opponent shall stop the clocks and ask for the arbiter's
assistance. The arbiter may penalise the player who displaced the pieces.
|
7.4 |
-
If during a game it is found that an illegal move has
been made, the position immediately before the irregularity shall be
reinstated. If the position immediately before the irregularity cannot be
determined the game shall continue from the last identifiable position
prior to the irregularity. The clocks shall be adjusted according to
Article 6.14. Article 4.3 applies to the move replacing the illegal move.
The game shall then continue from this reinstated position.
-
After the action taken under Article 7.4(a), for the
first two illegal moves by a player the arbiter shall give two minutes
extra time to his opponent in each instance; for a third illegal move by
the same player, the arbiter shall declare the game lost by this player.
|
7.5 |
If during a game it is found that pieces have been
displaced from their squares, the position before the irregularity shall be
re-instated. If the position immediately before the irregularity cannot be
identified, the game shall continue from the last identifiable position
prior to the irregularity. The clocks shall be adjusted according to Article
6.14. The game shall then continue from this re-instated position. |
Article 8: The recording of the moves
|
8.1 |
In the course of play each player is required to record
his own moves and those of his opponent in the correct manner, move after
move, as clearly and legibly as possible, in the algebraic notation
(Appendix E), on the 'scoresheet' prescribed for the competition.
A player may reply to his opponent's move before recording it, if he so
wishes. He must record his previous move before making another. Both players
must record the offer of a draw on the scoresheet. (Appendix E.12)
If a player is unable to keep score, an amount of time, decided by the
arbiter, shall be deducted from his allotted time at the beginning of the
game. |
8.2 |
The scoresheet shall be visible to the arbiter throughout
the game. |
8.3 |
The scoresheets are the property of the organisers of the
event. |
8.4 |
If a player has less than five minutes left on his clock
and does not have additional time of 30 seconds or more added with each
move, then he is not obliged to meet the requirements of Article 8.1.
Immediately after one flag has fallen the player must update his scoresheet
completely before moving a piece on the chessboard. |
8.5 |
-
If neither player is required to keep score under
Article 8.4, the arbiter or an assistant should try to be present and keep
score. In this case, immediately after one flag has fallen, the arbiter
shall stop the clocks. Then both players shall update their scoresheets,
using the arbiter's or the opponent's scoresheet.
-
If only one player is not required to keep score under
Article 8.4 he must, as soon as either flag has fallen, update his
scoresheet completely before moving a piece on the chessboard. Provided it
is the player's move, he may use his opponent's scoresheet, but must
return it before making a move
-
If no complete scoresheet is available, the players
must reconstruct the game on a second chessboard under the control of the
arbiter or an assistant. He shall first record the actual game position,
clock times and the number of moves made, if this information is
available, before reconstruction takes place.
|
8.6 |
If the scoresheets cannot be brought up to date showing
that a player has overstepped the allotted time, the next move made shall be
considered as the first of the following time period, unless there is
evidence that more moves have been made. |
8.7 |
At the conclusion of the game both players shall sign
both scoresheets, indicating the result of the game. Even if incorrect, this
result shall stand, unless the arbiter decides otherwise. |
Article 9: The drawn game |
9.1 |
-
A player wishing to offer a draw shall do so after
having made a move on the chessboard and before stopping his clock and
starting the opponent's clock. An offer at any other time during play is
still valid, but Article 12.5 must be considered. No conditions can be
attached to the offer. In both cases the offer cannot be withdrawn and
remains valid until the opponent accepts it, rejects it orally, rejects it
by touching a piece with the intention of moving or capturing it, or the
game is concluded in some other way.
-
The offer of a draw shall be noted by each player on
his scoresheet with a symbol (See Appendix E).
-
A claim of a draw under 9.2, 9.3 or 10.2 shall be
considered to be an offer of a draw.
|
9.2 |
The game is drawn, upon a correct claim by the player
having the move, when the same position, for at least the third time (not
necessarily by sequential repetition of moves)
-
is about to appear, if he first writes his move on his
scoresheet and declares to the arbiter his intention to make this move, or
-
has just appeared, and the player claiming the draw has
the move.
Positions as in (a) and (b) are considered the same, if
the same player has the move, pieces of the same kind and colour occupy the
same squares, and the possible moves of all the pieces of both players are
the same.
Positions are not the same if a pawn that could have been captured en
passant can no longer be captured or if the right to castle has been changed
temporarily or permanently. |
9.3 |
The game is drawn, upon a correct claim by the player
having the move, if
-
he writes on his scoresheet, and declares to the
arbiter his intention to make a move which shall result in the last 50
moves having been made by each player without the movement of any pawn and
without the capture of any piece, or
-
the last 50 consecutive moves have been made by each
player without the movement of any pawn and without the capture of any
piece.
|
9.4 |
If the player makes a move without having claimed the
draw he loses the right to claim, as in Article 9.2 or 9.3, on that move.
|
9.5 |
If a player claims a draw as in Article 9.2 or 9.3, he
shall immediately stop both clocks. He is not allowed to withdraw his claim.
-
If the claim is found to be correct the game is
immediately drawn.
-
If the claim is found to be incorrect, the arbiter
shall add three minutes to the opponent's remaining time. Additionally, if
the claimant has more than two minutes on his clock the arbiter shall
deduct half of the claimant's remaining time up to a maximum of three
minutes. If the claimant has more than one minute, but less than two
minutes, his remaining time shall be one minute. If the claimant has less
than one minute, the arbiter shall make no adjustment to the claimant's
clock. Then the game shall continue and the intended move must be made.
|
9.6 |
The game is drawn when a position is reached from which a
checkmate cannot occur by any possible series of legal moves, even with the
most unskilled play. This immediately ends the game. |
Article 10: Quickplay Finish |
10.1 |
A 'quickplay finish' is the last phase of a game, when
all the remaining moves must be made in a limited time. |
10.2 |
If the player, having the move, has less than two minutes
left on his clock, he may claim a draw before his flag falls. He shall stop
the clocks and summon the arbiter.
-
If the arbiter agrees the opponent is making no effort
to win the game by normal means, or that it is not possible to win by
normal means, then he shall declare the game drawn. Otherwise he shall
postpone his decision or reject the claim.
-
If the arbiter postpones his decision, the opponent may
be awarded two extra minutes thinking time and the game shall continue in
the presence of an arbiter, if possible. The arbiter shall declare the
final result after a flag has fallen.
-
If the arbiter has rejected the claim, the opponent
shall be awarded two extra minutes thinking time.
-
The decision of the arbiter shall be final relating to
10.2 a, b, c.
|
10.3 |
If both flags have fallen and it is impossible to
establish which flag fell first the game is drawn. |
Article 11: Scoring |
11.1 |
Unless announced otherwise in advance, a player who wins
his game, or wins by forfeit, scores one point (1), a player who loses his
game, or forfeits scores no points (0) and a player who draws his game
scores a half point (1/2). |
Article 12: The conduct of the players
|
12.1 |
The players shall take no action that will bring the game
of chess into disrepute. |
12.2 |
During play the players are forbidden to make use of any
notes, sources of information, advice, or to analyse on another chessboard.
The scoresheet shall be used only for recording the moves, the times of the
clocks, the offer of a draw, and matters relating to a claim. |
12.3 |
Players who have finished their games shall be considered
to be spectators. |
12.4 |
Players are not allowed to leave the 'playing venue'
without permission from the arbiter. The playing venue is defined as the
playing area, rest rooms, refreshment area, area set aside for smoking and
other places as designated by the arbiter.
The player having the move is not allowed to leave the playing area without
permission of the arbiter. |
12.5 |
It is forbidden to distract or annoy the opponent in any
manner whatsoever. This includes unreasonable claims or offers of a draw.
|
12.6 |
Infraction of any part of the Articles 12.1 to 12.5 shall
lead to penalties in accordance with Article 13.4. |
12.7 |
Persistent refusal by a player to comply with the Laws of
Chess shall be penalised by loss of the game. The arbiter shall decide the
score of the opponent. |
12.8 |
If both players are found guilty according to Article
12.7, the game shall be declared lost by both players. |
Article 13: The role of the arbiter (see
Preface) |
13.1 |
The arbiter shall see that the Laws of Chess are strictly
observed. |
13.2 |
The arbiter shall act in the best interest of the
competition. He should ensure that a good playing environment is maintained
and that the players are not disturbed. He shall supervise the progress of
the competition. |
13.3 |
The arbiter shall observe the games, especially when the
players are short of time, enforce decisions he has made and impose
penalties on players where appropriate. |
13.4 |
The arbiter can apply one or more of the following
penalties:
-
warning,
-
increasing the remaining time of the opponent,
-
reducing the remaining time of the offending player,
-
declaring the game to be lost,
-
reducing the points scored in a game by the offending
party,
-
increasing the points scored in a game by the opponent
to the maximum available for that game,
-
expulsion from the event.
|
13.5 |
The arbiter may award either or both players additional
time in the event of external disturbance of the game. |
13.6 |
The arbiter must not intervene in a game except in cases
described by the Laws of Chess. He shall not indicate the number of moves
made, except in applying Article 8.5, when at least one player has used all
his time. The arbiter shall refrain from informing a player that his
opponent has completed a move. |
13.7 |
Spectators and players in other games are not to speak
about or otherwise interfere in a game. If necessary, the arbiter may expel
offenders from the playing venue. |
Article 14: FIDE |
14.1 |
Member federations may ask FIDE to give an official
decision about problems relating to the Laws of Chess. |
