What Is The Threefold Repetition In Chess? The threefold repetition rule states that if a game reaches the same position three times, a draw can be claimed. A position is repeated if all pieces of the same kind and color are on identical squares, and all possible moves are the same.
Is perpetual check a win?
In the game of chess, perpetual check is a situation in which one player can force a draw by an unending series of checks. This typically arises when the player who is checking cannot deliver checkmate, and failing to continue the series of checks gives the opponent at least a chance to win.
When to make a claim in threefold repetition?
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. By contrast, the fivefold repetition rule requires the arbiter to intervene and declare the game drawn if the same position occurs five times, and requires no claim by the players.
When does a threefold repetition of a move occur?
Although a threefold repetition usually occurs after consecutive moves, there is no requirement that the moves be consecutive for a claim to be valid. The intermediate positions and moves do not matter – they can be the same or different.
Why are there threefold repetitions in a game?
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 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.
What are the rules for threefold repetition in chess?
The rules for the first official World Chess Championship 1886 match between Wilhelm Steinitz and Johannes Zukertort stated: “… if both players repeat the same series of moves six times in succession, then either player may claim a draw.” In two of the games the same position was repeated three times.
