7 The F.I.D.E. Laws Of Chess
8 ==========================
13 The Laws of Chess cannot cover all possible situations that may
14 arise during a game, nor can they regulate all administrative questions.
15 Where cases are not precisely regulated by an Article of the Laws, it
16 should be possible to reach a correct decision by studying analogous
17 situations which are discussed in the Laws.
19 The Laws assume arbiters have the necessary competence, sound
20 judgment and absolute objectivity. Too detailed a rule might deprive
21 the arbiter of his freedom of judgment and thus prevent him from finding
22 the solution to a problem dictated by fairness, logic and special factors.
24 F.I.D.E. appeals to all chess players and federations to accept
25 this view. Any chess federation that already operates, or wants to
26 introduce, more detailed rules is free to do so, provided:
28 (a) they do not conflict in any way with the official
29 F.I.D.E. Laws of Chess;
31 (b) they are limited to the territory of the federation in
34 (c) they are not valid for any F.I.D.E. match, championship,
35 or qualifying event, or to a F.I.D.E. title or rating tournament.
37 In the Articles of these Laws, "he", "him" and "his" can refer to
38 "she", "her" and "hers".
42 Article 1: The Chessboard
43 ---------- --------------
45 The game of chess is played between two opponents by moving pieces
46 on a square board called a "chessboard".
48 1.1 The chessboard is composed of 64 equal squares, alternately light
49 (the "white" squares) and dark (the "black" squares).
51 1.2 The chessboard is placed between the players in such a way that
52 the near corner to the right of each player is white.
54 1.3 The eight vertical rows of squares are called "files".
56 1.4 The eight horizontal rows of squares are called "ranks".
58 1.5 The lines of squares of the same colour, touching corner to corner,
59 are called "diagonals".
66 2.1 At the beginning of the game, one player has 16 light-coloured
67 pieces (the "white" pieces), the other has 16 dark-coloured
68 pieces (the "black" pieces.
70 2.2 These pieces are as follows:
71 A white king: K A black king: k
72 A white queen: Q A black queen: q
73 Two white rooks: R Two black rooks: r
74 Two white knights: N Two black knights: n
75 Two white bishops: B Two black bishops: b
76 Eight white pawns: P Eight black pawns: p
78 2.3 The initial position of the pieces on the chessboard is as follows:
80 |---|---|---|---|---|---|---|---|
81 | r | n | b | q | k | b | n | r | -- this square is "black"
82 |---|---|---|---|---|---|---|---|
83 | p | p | p | p | p | p | p | p |
84 |---|---|---|---|---|---|---|---|
85 | | . | | . | | . | | . |

93 | P | P | P | P | P | P | P | P |
94 |---|---|---|---|---|---|---|---|
95 | R | N | B | Q | K | B | N | R | -- this square is "white"
96 |---|---|---|---|---|---|---|---|
100 Article 3: The Right To Move
101 ---------- -----------------
103 3.1 The player with the white pieces commences the game. The players
104 alternate in making one move at a time until the game is completed.
106 3.2 A player is said to "have the move" when his opponent's move
111 Article 4: The General Definition Of The Move
112 ---------- ----------------------------------
114 4.1 With the exception of castling (Article 5.1(b)), a move is the
115 transfer by a player of one of his pieces from one square to
116 another square, which is either vacant or occupied by an opponent's
118 [A capture is, therefore, merely a certain type of move.]
120 4.2 No piece, except the rook when castling (Article 5.1(b)) and the
121 knight (Article 5.5), may cross a square occupied by another piece.
123 4.3 A piece played to a square occupied by an opponent's piece captures
124 it as part of the same move. The captured piece must be removed
125 immediately from the chessboard by the player making the capture
126 (see Article 5.6(c) for capturing "en passant").
130 Article 5: The Moves Of The Pieces
131 ---------- -----------------------
134 (a) Except when castling, the king moves to any adjoining square
135 that is not attacked by an opponent's piece.
136 (b) Castling is a move of the king and either rook, counting as a
137 single move of the king and executed as follows: the king is
138 transferred from its original square two squares toward either
139 rook on the same rank; then that rook is transferred over the
140 king to the square the king has just crossed.
141 (c) If a player touches a rook and then his king, he may not castle
142 with that rook and the situation will by governed by Articles
143 7.2 and 7.3 [Touched Piece rules].
144 (d) If a player, intending to castle, touches the king first, or
145 king and rook at the same time, and it then appears that castling
146 is illegal, the player may choose either to move his king or to
147 castle on the other side, provided that castling on that side is
148 legal. If the king has no legal move, the player is free to make
150 (e) Castling is [permanently] illegal:
151 (i) if the king has already been moved; or
152 (ii) with a rook that has already been moved.
153 (f) Castling is prevented for the time being:
154 (i) if the king's original square, or the square which the king
155 must pass over, or that which it is to occupy, is attacked
156 by an opponent's piece; or
157 (ii) if there is any piece between the king and the rook with
158 which castling is to be effected [i.e. castling may still
159 be legal even if the rook is attacked or, when castling
160 queenside, passes over an attacked square] .
163 The queen moves to any square (except as limited by Article 4.2)
164 [No leapfrogging] on the file, rank, or diagonals on which it stands.
167 The rook moves to any square (except as limited by Article 4.2) on the
168 file or rank on which it stands.
171 The bishop moves to any square (except as limited by Article 4.2) on
172 the diagonals on which it stands.
175 The knight's move is composed of two different steps; first, it makes
176 one step of one single square along its rank or file, and then, still
177 moving away from the square of departure, one step of one single
178 square on a diagonal. It does not matter if the square of the first
182 (a) The pawn may move only forward [except as limited by Article 4.2].
183 (b) Except when making a capture, it advances from its original
184 square either one or two vacant squares along the file on which
185 it is placed, and on subsequent moves it advances one vacant
186 square along the file. When capturing, it advances one square
187 along either of the diagonals on which it stands.
188 (c) A pawn, attacking a square crossed by an opponent's pawn which
189 has [just] been advanced two squares in one move from its
190 original square, may capture this opponent's pawn as though the
191 latter had been moved only one square. This capture may only be
192 made in [immediate] reply to such an advance, and is called an
193 "en passant" capture.
194 (d) On reaching the last rank, a pawn must immediately be exchanged,
195 as part of the same move, for [either] a queen, a rook, a bishop,
196 or a knight, of the same colour as the pawn, at the player's
197 choice and without taking into account the other pieces still
198 remaining on the chessboard. This exchange of a pawn for another
199 piece is called "promotion", and the effect of the promoted
200 piece is immediate [and permanent!].
201 (e) In a competition, if a new piece required for the promotion is
202 not immediately available, the player may stop his clock to ask
203 for the assistance of the arbiter. The player must complete his
204 move correctly, in the manner specified in Article 5.6(d).
208 Article 6: The Completion Of The Move
209 ---------- --------------------------
213 6.1 in the case of the transfer of a piece to a vacant square, when
214 the player's hand has released the piece;
216 6.2 in the case of a capture, when the captured piece has been removed
217 from the chessboard and the player, having placed his own piece on
218 its new square, has released this [capturing] piece from his hand;
220 6.3 in the case of castling, when the player's hand has released the
221 rook on the square [previously] crossed by the king. When the player
222 has released the king from his hand, the move is not yet completed,
223 but the player no longer has the right to make any move other than
224 castling on that side, if this is legal;
226 6.4 in the case of the promotion of a pawn, when the pawn has been
227 removed from the chessboard and the player's hand has released the
228 new piece after placing it on the promotion square. If the player
229 has released from his hand the pawn that has reached the promotion
230 square, the move is not yet completed, but the player no longer has
231 the right to play the pawn to another square.
233 6.5 When determining whether the prescribed number of moves has been made
234 in the allotted time, the last move is not considered complete until
235 after the player has stopped his clock. This applies to all situations
236 except those governed by Articles 10.1, 10.2, 10.3, 10.4 and 10.6.
237 [i.e. when the move has been completed in the sense of Articles 6.1-6.4,
238 and the game ends immediately after the move in question, which may,
239 for example, put the player's opponent into checkmate. This Law was
240 introduced to prevent the situation where a player returns to the board
241 to claim a win on time, possibly an hour after being checkmated!] .
245 Article 7: The Touched Piece
246 ---------- -----------------
248 7.1 Provided that he first expresses his intention (e.g. by saying
249 "j'adoube"), the player having the move may adjust one or more pieces
251 [If a player's opponent is absent from the chessboard, it is best to
252 inform one of his team-mates, or some other witness.]
254 7.2 Except for the above case, if the player having the move deliberately
255 touches on the board:
256 (a) one or more pieces of the same colour, he must move or capture
257 the first piece he touched that can be moved or captured; or
258 (b) one of his own pieces and one of his opponent's pieces, he must
259 capture his opponent's piece with his own piece; or, if this is
260 illegal, move or capture the first piece he touched that can be
261 moved or captured. If it is impossible to establish which piece
262 was touched first, the player's piece shall be considered the
265 7.3 If none of the touched pieces has a legal move (or if none of the
266 opponent's pieces which were touched can be captured legally), the
267 player is free to make any legal move.
269 7.4 If a player wishes to claim that his opponent has violated Article
270 7.2, he must do so before he himself touches a piece.
271 [Note that the clause "deliberately touches" protects a player from
272 having to move a piece accidentally touched by his elbow/wrist etc]
276 Article 8: Illegal Positions
277 ---------- -----------------
279 8.1 If, during a game, it is found that an illegal move was made, the
280 position shall be reinstated to what it was before the illegal move
281 was made. The game shall then continue by applying the rules of
282 Article 7 to the move replacing the illegal move. If the position
283 cannot be reinstated, the game shall be annulled and a new game
284 played. This applies to all sessions of play, and to a game awaiting
285 a decision by adjudication.
286 [Note that this discovery of an illegal move must be made while the
287 game is still in progress, before resignation or the agreement of a
288 draw. The only possible exception can be if the illegal move itself
289 would theoretically end the game: anyone trying the trick 1. e2-e4
290 e7-e5; 2. Bf1-c4 Ng8-f6; 3. Qd1xf7 "mate" may be penalised under
291 Article 10.17! Note that the act of playing an illegal move, at ANY
292 stage of the game, does not IN ITSELF forfeit the game.]
294 8.2 If, during a game, one or more pieces have been accidentally
295 displaced and incorrectly replaced, the position before the
296 displacement occurred shall be reinstated, and the game shall
297 continue. If the position cannot be reinstated, the game shall be
298 annulled and a new game played.
300 8.3 If a player moves and in the course of this inadvertently knocks
301 over a piece, or several pieces, he must re-establish the position
304 8.4 If, after an adjournment, the position is incorrectly set up, the
305 position as it was on adjournment must be set up again and the game
308 8.5 If, during a game, it is found that the initial position of the
309 pieces was incorrect, the game shall be annulled and a new game played.
311 8.6 If a game has begun with colours incorrectly reversed, then it shall
312 continue if more than one quarter of the time allocated to both
313 players to the first time control has elapsed. Earlier, the arbiter
314 can arrange for a new game to start with the correct colours, if the
315 event's timetable is not excessively disrupted.
317 8.7 If, during a game, it is found that the board has been placed contrary
318 to Article 1.2, the position reached should be transferred to a
319 correctly-placed board, and the game continued.
320 [In the situations covered by Articles 8.5-8.7, a spectator is
321 justified in pointing out to the arbiter the error he has noticed.
322 In Article 8.7, the implicit assumption is that the relative
323 positions of the pieces relative to one another were correct] .
330 9.1 The king is in "check" when the square it occupies is attacked by
331 one or more of the opponent's pieces; in this case, the latter is/are
332 said to be "checking" the king. A player may not make a move which
333 leaves his king on a square attacked by any of his opponent's pieces.
335 9.2 Check must be parried by the move immediately following. If any check
336 cannot be parried, the king is said to be "checkmated" ("mated").
337 9.3 Declaring a check is not obligatory.
338 [Merely polite! Playing an illegal move does not imply the loss of
339 the game: see Article 8.1.]
343 Article 10: The Completed Game
344 ----------- ------------------
346 10.1 The game is won by the player who has checkmated his opponent's
347 king. This immediately ends the game.
349 10.2 The game is won by the player whose opponent declares he resigns.
350 This immediately ends the game.
352 10.3 The game is drawn when the king of the player who has the move is
353 not in check, and this player cannot make any legal move. The player's
354 king is then said to be "stalemated". This immediately ends the game.
355 [If the stalemating move was actually legal!] .
357 10.4 The game is drawn when one of the following endings arises:
358 (a) king against king;
359 (b) king against king with only bishop or knight;
360 (c) king and bishop against king and bishop, with both bishops
361 on diagonals of the same colour.
362 This immediately ends the game.
364 10.5 A player having a bare king cannot win the game. A draw shall be
365 declared if the opponent of a player with a bare king oversteps the
366 time limit (Articles 10.13 and 10.14) or seals an illegal move
369 10.6 The game is drawn upon agreement between the two players. This
370 immediately ends the game.
372 10.7 A proposal of a draw under the provisions of Article 10.6 may be
373 made by a player only at the moment when he has just moved a piece.
374 On then proposing a draw, he starts the clock of his opponent. The
375 latter may accept the proposal, which is always to be taken as
376 unconditional, or he may reject it either orally or by completing a
377 move. A draw offer is valid until the opponent has accepted or
379 [The gamesmanship question "Are you playing for a win?" can be
380 considered as an offer of a draw] .
382 10.8 If a player proposes a draw while his opponent's clock is running
383 and his opponent is contemplating his move, the opponent may still
384 agree to the draw or reject the offer. A player who offers a draw
385 in this manner may be penalised by the arbiter.
387 10.9 If a player proposes a draw while his own clock is running or after
388 his move has been sealed, the opponent may postpone his decision
389 until after he has seen the first player's move.
391 10.10 The game is drawn, upon a claim by the player having the move, when
392 the same position, for the third time:
393 (a) is about to appear, if he first writes the move on his scoresheet
394 and declares to the arbiter his intention of making this move; or
395 (b) has just appeared, the same player having the move each time.
396 The position is considered the same if pieces of the same kind and
397 colour occupy the same squares, and if all the possible moves of all
398 the pieces are the same, including the rights to castle [at some
399 future time] or to capture a pawn "en passant".
401 10.11 If a player executes a move without having claimed a draw for one
402 of the reasons stated in Article 10.10, he loses the right to claim
403 a draw. This right is restored to him, however, if the same position
404 [later] appears again, the same player having the move.
406 10.12 The game is drawn when a player having the move claims a draw and
407 demonstrates that at least [the last?] 50 consecutive moves have been
408 made by each side without the capture of any piece and without the
409 movement of any pawn. This number of 50 moves can be increased for
410 certain positions, provided that this increase in number and these
411 positions have been clearly announced by the organisers before the
413 [The claim then proceeds according to 10.13. The most extreme case
414 yet known of a position which might take more than 50 moves to win is
415 king, rook and bishop against king and two knights, which can run for
416 223 moves between captures!]
418 10.13 If a player claims a draw under the provisions of Articles 10.10
419 and/or 10.12, the arbiter must first stop the clocks while the claim
420 is being investigated. In the absence of the arbiter, a player may
421 stop both clocks to seek the arbiter's assistance.
422 (a) If the claim is found to be correct, the game is drawn.
423 (b) If the claim is found to be incorrect, the arbiter shall then
424 add five minutes to the claimant's used time. If this means that
425 the claimant has [now] overstepped the time limit, his game will
426 be declared lost. Otherwise, the game will be continued, and a
427 player who has indicated a move according to Article 10.10(a) is
428 obliged to execute this move on the chessboard.
429 (c) A player who has made a claim under these Articles cannot
432 10.14 The game is lost by a player who has not completed the prescribed
433 number of moves in the allotted time, unless his opponent has only
434 the king remaining, in which case the game is drawn. (See Articles 6.5
436 [Situations when Articles 10.1-10.4 or 10.6 apply are the only other
439 10.15 The game is lost by a player who arrives at the chessboard more than
440 one hour late, for the beginning of the game or for the resumption of
441 an adjourned game. The time of delay is counted from the [scheduled]
442 start of the playing session. However, in the case of an adjourned
443 game, if the player who made the sealed move is the late player, the
444 game is decided otherwise if:
445 (a) the absent player has won the game by virtue of the fact that
446 the sealed move is checkmate; or
447 (b) the absent player has produced a drawn game by virtue of the
448 fact that the sealed move is stalemate, or if one of the
449 positions in Article 10.4 has arisen as a consequence of the
451 (c) the player present at the chessboard has lost the game according
452 to Article 10.14 by exceeding his time limit.
454 10.16 At the resumption, the game is lost by a player whose recording
457 (b) would result in a false move the true significance of which is
458 impossible to establish; or
459 (c) would result in an illegal move.
461 10.17 The game is lost by a player who, during the game, refuses to comply
462 with the Laws. If both players refuse to comply with the Laws, or if
463 both players arrive at the chessboard more than one hour late, the
464 game shall be declared lost by both players.
468 Article 11: The Recording Of Games
469 ----------- ----------------------
471 11.1 In the course of play, each player is required to record the game
472 (his own moves and those of his opponent), move after move, as
473 clearly and legibly as possible in the Algebraic Notation, on the
474 scoresheet prescribed for the competition. It is irrelevant whether
475 the player first makes his move and then records it, or vice versa.
476 [The use of Descriptive Notation or foreign versions of Algebraic
477 Notation is tolerated in internal tournaments, e.g. weekend
480 11.2 If a player has less than five minutes on his clock until the time
481 control, he is not obliged to meet the requirements of Article 11.1.
482 As soon as the special device (e.g. the flag) on the clock indicates
483 the end of his allotted time, the player must immediately complete
484 his record of the game by filling in the moves omitted from his
486 [A player may be justified in restarting his opponent's clock,
487 without having to make a move, if his opponent has more than 5 minutes
488 left and is not fulfilling the requirements of Article 11.1. A player
489 cannot stop his clock unless he has recorded at least his opponent's
490 last move and all previous moves of the game.]
492 11.3 If both players cannot keep score, the arbiter, or his deputy, must
493 endeavour to be present and keep score. The arbiter must not intervene
494 unless one flag falls, and until then he should not indicate in any
495 manner to the players how many moves have been made.
497 11.4 If Article 11.2 does not apply, and a player refuses to record the
498 game according to Article 11.1, then Article 10.17 should be applied
499 [Failure to comply with the Laws of Chess].
501 11.5 If a player does not refuse to comply with the arbiter's request for
502 a completed scoresheet, but declares that he cannot complete his
503 scoresheet without consulting his opponent's, the request for this
504 scoresheet must be made to the arbiter, who will determine whether
505 the scoresheet can be completed before the time-control without
506 inconveniencing the other player. The latter cannot refuse his
507 scoresheet, because the scoresheet belongs to the organisers and the
508 reconstruction will be made in his opponent's time. In all other
509 cases, the scoresheets can be completed only after the time-control.
511 11.6 If, after the time-control, one player alone has to complete his
512 scoresheet, he will do so before making another move, and with his
513 clock running if his opponent has moved.
515 11.7 If, after the time-control, both players need to complete their
516 scoresheets, both clocks will be stopped until the two scoresheets
517 are completed, if necessary with the help of the arbiter's scoresheet
518 and/or a chessboard under the control of the arbiter, who should have
519 recorded the actual game position beforehand.
520 [In case this position gets disturbed!]
522 11.8 If, in Article 11.6, the arbiter sees that the scoresheets alone cannot
523 help in the reconstruction of the game, he will act as in Article 11.7.
525 11.9 If it proves impossible to reconstruct the moves as prescribed under
526 Article 11.7, the game shall continue. In this case, the next move
527 played will be considered to be the first one of the following
532 Article 12: The Chess Clock
533 ----------- ---------------
535 12.1 Each player must make a certain number of moves in an allotted period
536 of time, these two factors being specified in advance. The time saved
537 by a player during one period is added to his time available for the
540 12.2 Control of each player's time is effected by means of a clock
541 equipped with a flag (or other special device) for this purpose.
542 The flag is considered to have fallen when the arbiter observes
543 the fact, or when the arbiter determines that the allotted time
544 has been exceeded, even though the flag, because of a defect,
545 has not fallen when the end of the minute hand has passed the
546 end of the flag. In cases where no arbiter is present, the flag
547 is considered to have fallen when a claim to that effect has been
550 12.3 At the time determined for the start of the game, the clock of the
551 player who has the white pieces is started. During the game, each
552 of the players, having completed his move, stops his own clock and
553 starts his opponent's clock.
555 12.4 Every indication given by a clock is considered to be conclusive
556 in the absence of evident defects. A player who wishes to claim
557 any such defect must do so as soon as he himself has become aware
558 of it, but not later than immediately after his flag has fallen
559 at the time-control. A clock with an obvious defect should be
560 replaced, and the time used by each player up to the time the
561 game was interrupted should be indicated on the new clock as
562 accurately as possible. The arbiter shall use his best judgment
563 in determining what times shall be shown on the new clock. If
564 the arbiter decides to add time used to the clock of one or both
565 of the players, he shall under no circumstances (except as provided
566 for in Article 10.13(b)) leave a player with:
567 (a) less than five minutes to the time-control; or
568 (b) less than one minute for every move to the time-control.
570 12.5 If the game needs to be interrupted for some reason which requires
571 action by the arbiter, the clocks shall be stopped by the arbiter.
572 This should be done, for example, in the case of an illegal position
573 being corrected, in the case of a defective clock being changed, or
574 if the piece which a player has declared he wishes to exchange for
575 a promoted pawn is not immediately available, or to claim a draw by
576 repetitions of position or under the 50 moves rule. If the arbiter
577 is not present, a player may stop both clocks in order to seek the
578 arbiter's assistance.
580 12.6 In the case of Articles 8.1 and 8.2 [Illegal Positions], when it is
581 not possible to determine the exact time used by each player up to
582 the moment when the irregularity occurred, each player shall be
583 allotted up to that moment a time proportional to that indicated by
584 the clock when the irregularity was ascertained.
585 For example, after Black's 30th move it is found that an irregularity
586 took place at the 20th move. For these 30 moves, the clock shows 90
587 minutes for White and 60 minutes for Black, so it is assumed that the
588 times used by the two players for the first 20 moves were as follows:
589 for White: 90 x 20/30 = 60 minutes
590 for Black: 60 x 20/30 = 40 minutes
591 This rule must not be used to leave a player with less than five
592 minutes to the time control, or less than one minute for every move
593 to the time control. (The most common occasion when this problem
594 arises is immediately after an adjournment, when the clock times can
595 be most easily adjusted using the times on the sealed move envelope.)
597 12.7 A resignation or an agreement to draw (Articles 10.2 and 10.4)
598 remains valid even if it is found later that a flag had fallen.
600 12.8 If both flags have fallen at virtually the same time [or if both
601 have fallen before a claim is made by either player] and the arbiter
602 is unable to establish clearly which flag fell first, the game shall
603 continue. In this case, if the scoresheets cannot be brought up to
604 date showing that the time control has been passed, the next move
605 played will be considered to be the first one of the following
608 12.9 The arbiter [and everyone else, for that matter] shall refrain from
609 calling a player's attention to the fact that his opponent has made a
610 move or that the player has forgotten to stop his clock after he has
611 made a move, or informing the player how many moves he has made, etc.
615 Article 13: The Adjournment Of The Game
616 ----------- ---------------------------
618 13.1 (a) If a game is not finished at the end of the time prescribed
619 for play, the player having the move must write his move in
620 unambiguous notation on his scoresheet, put his scoresheet and
621 that of his opponent in an envelope, seal the envelope, and
622 only then stop his clock without starting his opponent's clock.
623 Until he has stopped the clocks, the player retains the right
624 to change his sealed move. If, after being told by the arbiter
625 to seal his move, the player makes a move on the chessboard, he
626 must write that same move on his scoresheet as his sealed move.
627 (b) A player having the move who adjourns the game before the end
628 of the playing session will have added to the used time on his
629 clock the whole of the remaining time to the end of the session.
631 13.2 Upon the envelope shall be indicated:
632 (a) the names of the players;
633 (b) the position immediately before the sealed move;
634 (c) the time used by each player;
635 (d) the name of the player who has sealed the move; and
636 (e) the number of the sealed move.
638 13.3 The arbiter is responsible for the safekeeping of the envelope
639 and should check the accuracy of the information on it.
643 Article 14: The Resumption of the Adjourned Game
644 ----------- ------------------------------------
646 14.1 When the game is resumed, the position immediately before the sealed
647 move shall be set up on the chessboard, and the time used by each
648 player when the game was adjourned shall be indicated on the clocks.
651 14.2 The envelope shall be opened only when the player who must reply to
652 the sealed move is present. This player's clock shall be started
653 after the sealed move has been made on the chessboard.
654 (a) If two players have agreed to a draw and announce their decision
656 (b) if one of the players in an adjourned game notifies the arbiter
657 that he resigns and it is found, when the envelope has been
658 opened, that the sealed move is invalid according to Article
659 10.16, then in (a) the draw stands and in (b) the resignation
662 14.3 If the player having to respond to the sealed move is absent, his
663 clock shall be started but the envelope containing the sealed move
664 shall be opened only when he arrives. The player's clock shall then
665 be stopped and restarted after the sealed move has been played on
668 14.4 If the player who has sealed the move is absent, the player having
669 the move is not obliged to reply to the sealed move on the chessboard.
670 He has the right to record his move in reply on his scoresheet, to
671 seal the scoresheet in an envelope, to stop his clock and start his
672 opponent's clock. The envelope should then be put into safekeeping
673 and opened on the opponent's arrival.
675 14.5 If the envelope containing the move recorded in accordance with
676 Article 13 has disappeared:
677 (a) the game shall be resumed from the position at the time of
678 adjournment and with the clock times recorded at the time of
680 (b) if it is impossible to re-establish the position, the game is
681 annulled and a new game must be played;
682 (c) if the time used at the time of the adjournment cannot be
683 re-established, this question is decided by the arbiter. The
684 player who sealed the move makes it on the board.
686 14.6 If, upon resumption of the game, the time used has been incorrectly
687 indicated on either clock, and if either player points this out
688 before making his first move, the error must be corrected. If the
689 error is not so established, the game continues without correction,
690 unless the arbiter feels that the consequences will be too severe.
692 14.7 The duration of each resumption session shall be controlled by the
693 wall clock, with the starting time and the finishing time announced
698 Article 15: The Conduct Of The Players
699 ----------- --------------------------
702 (a) During play, the players are forbidden to make use of
703 hand-written, printed or otherwise recorded matter, or to
704 analyse the game on another chessboard. They are also forbidden
705 to have recourse to the advice of a third party, whether
707 [The only possible exception is that a player in a team
708 competition may be allowed to ask his captain "Should I accept
709 his offer of a draw?" or "Does the team need me to play for a
710 win?". The captain or acting-captain must limit his reply to an
711 immediate "Yes", "No", or "It's up to you", without supplying
712 his answer after a detailed analysis of the position, and without
713 making his answer emphatic in any way. This captain, like all his
714 players, is not allowed to receive opinions, from any source, on
715 the states of play of any games still in progress] .
716 (b) The use of notes made during the game as an aid to memory is
717 also forbidden, aside from the actual recording of the moves
718 and the times on the clocks.
719 (c) No analysis is permitted in the playing rooms during play or
720 during resumption sessions.
721 (d) It is forbidden to distract or annoy the opponent in any manner
722 whatsoever. This includes the persistent offering of a draw.
724 15.2 Infractions of the rules indicated in Article 15.1 may incur penalties
725 even to the extent of the loss of the game (see Article 16.5).
729 Article 16: The Arbiter
730 ----------- -----------
732 An arbiter should be designated to control the competition. His
735 16.1 to see that the Laws are strictly observed;
737 16.2 to supervise the progress of the competition, to establish that the
738 prescribed time-limit has not been exceeded by the players, to arrange
739 the order of resumption of play of adjourned games, to see that the
740 arrangements contained in Article 13 are observed (i.e. to see that
741 the information on the envelope is correct), to keep the sealed-move
742 envelope until the resumption of the adjourned game, etc;
744 16.3 to enforce the decisions he may make in disputes that have arisen
745 during the course of the competition;
747 16.4 to act in the best interests of the competition to ensure that a good
748 playing environment is maintained and that the players are not
749 disturbed by each other or by the audience;
751 16.5 to impose penalties on the players for any fault or infraction of
752 the Laws. These penalties may include a warning, a time penalty
753 (by adding to the player's used time or to his opponent's unused time)
754 or even the loss of the game.
761 For a won game, the winner gets 1 (one) point and the loser 0 (zero).
762 For a draw, each player gets (half) a point.
766 Article 18: The Interpretation of the Laws
767 ----------- ------------------------------
769 In case of doubts as to the application or interpretation of the Laws,
770 F.I.D.E. will examine the evidence and render official decisions.
771 Rulings published are binding on all affiliated federations. All
772 proposals and questions about interpretations should be submitted by
773 member federations, with complete data.
