1. Play is governed by the World Championship Technical Regulations (annex 1), which apply with the exceptions mentioned below in (2), (3) and (4).

2. The players do not need to record the moves. An arbiter shall record the moves.

3. The player who has the move may stop the clocks and consult the Arbiter’s score sheet and if his next move will produce a threefold repetition of position (according to Article 9.2a of the Technical Regulations), or the 50 moves rule (according to Article 9.3a of the Technical Regulations), he himself must write the intended move on the score sheet and claim the draw if he wants. A player can also claim a draw according to Articles 9.2b and 9.3b of the Technical Regulations. If the claim is found to be correct, the game is immediately ended as a draw. If the claim is found to be incorrect, the Arbiter shall add three (3) minutes to the opponent’s remaining time and the game continues with the intended move in accordance with Article 4 of the Technical Regulations. A maximum of two (2) incorrect claims for a draw can be made by each player. If a player makes a third (3^rd ) incorrect claim, the arbiter shall declare the game lost for this player.

4. If a game has ended by resignation, checkmate, time loss, stalemate, triple repetition or any other of the ways described in Article 5 of the Technical Regulations, no claim for irregularities shall be accepted (irregularities include clock settings and all other described in Article 7 of the Technical Regulations).
