Article 6: The chess clock
- 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 expiry of the allotted time for a player.
- When using a chess clock, each player must make a certain number or all moves in an allotted period of time and/or may be allocated an additional amount of time after each move. All this 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. They also receive a fixed extra time for every move. The count down of the main time only commences after the fixed time has expired. Provided the player stops his clock before the expiry of the fixed time, the main thinking time does not change, irrespective of the proportion of the fixed time used.
- Each time display has a flag. Immediately after a flag falls, the requirements of Article 6.2 must be checked.
- The arbiter decides where the chess clock is placed.
- At the time determined for the start of the game the clock of the player who has the white pieces is started.
- The player shall lose the game if he arrives at the chessboard more than one hour after the scheduled start of the session (unless the rules of the competition specify or the arbiter decides otherwise).
- 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 made move ends the game. (See Articles 5.1, 5.2 and 5.3) 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 to keep the 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.
- A flag is considered to have fallen when the arbiter observes the fact or when a valid claim to that effect has been made by either player.
- Except where Articles 5.1, 5.2 and 5.3 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 by any possible series of legal moves, even with the most unskilled counterplay).
- 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 chessclock.
- If both flags have fallen and it is impossible to establish which flag fell first, the game shall continue.
- If the game needs to be interrupted, the arbiter shall stop the clocks.
- A player may stop the clocks in order to seek the arbiter's assistance.
- The arbiter shall decide when the game is to be restarted.
- 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.
- 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 anything shown in this manner.

Article 7: Illegal positions
- 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.
- If a game has begun with colours reversed then it shall continue, unless the arbiter rules otherwise.
- If a player displaces one or more pieces, he shall reestablish the correct position on his own time. If necessary the opponent has the right to restart the player's clock without making a move in order to make sure the player reestablishes the correct position on his own time.
- If during a game it is found that an illegal move has been made, or that pieces have been displaced from their squares, the position before the irregularity shall be reinstated. 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 6.13 and, in the case of an illegal move, Article 4.3 applies to the move replacing the illegal move. The game shall then continue.

Article 8: The recording of the moves
- In the course of play each player is required to record his own moves and those of his opponent, 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. The offer of a draw must be recorded on the scoresheet by both players. If a player due to physical or religious reasons, 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.
- The scoresheet shall be visible to the arbiter at all times.
- The scoresheets are the property of the organisers of the event.
- 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.
- 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 update his scoresheet completely as soon as a flag has fallen. Provided it is the player's move, he may use his opponent's scoresheet. The player is not permitted to move until after he has completed his own scoresheet and returned his opponent's.
- 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, who shall first record the actual game position before reconstruction takes place.
- 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.

Article 9: The drawn game
- A player can propose a draw after making a move on the chessboard. He must do so before stopping his own clock and starting his 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 making a move, or the game is concluded in some other way. The offer of a draw shall be noted by each player on his scoresheet with the symbol (=).
- 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 repetition of moves)
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 could have been captured en passant or if the right to castle immediately or in the future has been changed.
- 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.
- 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.
- 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.
- 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 deduct half of the claimant's remaining time up to a maximum of three minutes and add three minutes to the opponent's remaining time. Then the game shall continue and the intended move must be made.
- 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
- A quickplay finish is the last phase of a game, when all the remaining moves must be made in a limited time.
- If the player 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 is satisfied 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.
- 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 the arbiter.
- Having postponed his decision, the arbiter may subsequently declare the game drawn, even after a flag has fallen.
- Illegal moves do not necessarily lose. After the action taken under Article 7.4, for a first illegal move by a player the arbiter shall give two minutes extra time to his opponent; for a second illegal move by the same player the arbiter shall give another two minutes extra time to his opponent; for a third illegal move by the same player, the arbiter shall declare the game lost by the player who played incorrectly..
- If both flags have fallen and it is impossible to establish which flag fell first the game is drawn.

Article 12: The conduct of the players
- High standards of etiquette are expected of the players.
- 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.
- No analysis is permitted in the playing area when play is in progress, whether by players or spectators. Players who have finished their games shall be considered to be spectators.
- The 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.
- It is forbidden to distract or annoy the opponent in any manner whatsoever; this includes the persistent offer of a draw.
- Infraction of any part of the Articles 12.2 to 12.5 shall lead to penalties in accordance with Article 13.4.
