FIDE's competitive rules of play allow a player to claim a draw in either of two situations: Fifty moves have been made by each player without a capture or pawn movement (this is the fifty-move rule); The same position has appeared three times (or has appeared twice and the player claiming the draw can force the third appearance); this is the threefold repetition rule. These rules help prevent games from being extended indefinitely in tournaments.
