A.1A ‘Rapid chess’ game is one where either all the moves must be completed in a fixed time of more than 10 minutes but less than 60 minutes for each player; or the time allotted plus 60 times any increment is of more than 10 minutes but less than 60 minutes for each player. A.2Players do not need to record the moves, but do not lose their rights to claims normally based on a scoresheet. The player can, at any time, ask the arbiter to provide him with a scoresheet, in order to write the moves. A.3.1The Competition Rules shall apply if: A.3.1.1one arbiter supervises at most three games and A.3.1.2each game is recorded by the arbiter or his assistant and, if possible, by electronic means. A.3.2The player may at any time, when it is his move, ask the arbiter or his assistant to show him the scoresheet. This may be requested a maximum of five times in a game. More requests shall be considered as a distraction of the opponent. A.4Otherwise the following apply: A.4.1From the initial position, once 10 moves have been completed by each player, A.4.1.1no change can be made to the clock setting, unless the schedule of the event
would be adversely affected A.4.1.2no claim can be made regarding incorrect set-up or orientation of the chessboard.
In case of incorrect king placement, castling is not allowed. In case of incorrect
rook placement, castling with this rook is not allowed. A.4.2If the arbiter observes an action taken under Article 7.5.1, 7.5.2, 7.5.3 or 7.5.4, he shall act according to Article 7.5.5, provided the opponent has not made his next move. If the arbiter does not intervene, the opponent is entitled to claim, provided the opponent has not made his next move. If the opponent does not claim and the arbiter does not intervene, the illegal move shall stand and the game shall continue. Once the opponent has made his next move, an illegal move cannot be corrected unless this is agreed by the players without intervention of the arbiter. A.4.3To claim a win on time, the claimant may stop the chessclock and notify the arbiter. However, the game is drawn if the position is such that the claimant cannot checkmate the player’s king by any possible series of legal moves. A.4.4If the arbiter observes both kings are in check, or a pawn on the rank furthest from its starting position, he shall wait until the next move is completed. Then, if an illegal position is still on the board, he shall declare the game drawn. A.4.5The arbiter shall also call a flag fall, if he observes it. A.5The regulations of an event shall specify whether Article A.3 or Article A.4 shall apply for the entire event.
