If an arbiter does not detect a fivefold repetition or fails to intervene, a player may still make a claim for fivefold repetition. If an arbiter detects a fivefold repetition, they are required to intervene and declare the game a draw. If the same position occurs five times, then the game is immediately terminated as a draw. In 2014 FIDE introduced a rule providing for a mandatory draw in the event of a fivefold repetition. Even if the claim is incorrect, any draw claim is also a draw offer that the opponent may accept. Unreasonable claims may be penalized under rule 11.5, which forbids distracting or annoying the opponent. If the claim for a draw is incorrect, the opponent is awarded an extra two minutes, the written move (if legal) move must be played and the game continues. Perpetual check is no longer specifically mentioned in the rules of chess such a situation will eventually resolve to a draw either by repetition, fifty-move rule or (most commonly) by agreement. The rule applies to positions, not moves. either king or one of the rooks has been moved, in between repetitions of the position.Īlthough a threefold repetition usually occurs after consecutive moves, there is no requirement that the moves be consecutive for a claim to be valid. (a) in the first position, a pawn could have been captured en passant (by the en passant rule, in the subsequent positions, the pawn cannot be captured en passant anymore), or (b) either player has lost a right to castle, i.e. Under (3) above, positions are not considered to be the same if: Positions are considered the same if (1) the same player has the move, (2) pieces of the same kind and color occupy the same squares, and (3) the possible moves of all the pieces are the same. or (b) If the position has just appeared for the third time, the player with the move can claim the draw. The claim is made: (a) If the position is about to appear for the third time, the player making the claim first writes their move on their scoresheet and notifies the arbiter that they intend to make this move.

By contrast, the fivefold repetition rule requires the arbiter to intervene and declare the game drawn if the same position occurs five times, needing no claim by the players. The claim must be made either before making the move which will produce the third repetition, or after the opponent has made a move producing a third repetition. ![]() The game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter. The reasoning behind the rule is that if the position occurs three times, no real progress is being made and the game could hypothetically continue indefinitely. The repeated positions need not occur in succession. ![]() Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture en passant is the same. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position.
