'''[[Main Page|Home]] * [[Search]] * Repetitions'''

'''Repetitions''' of [[Chess Position|positions]] may happen during [[Chess Game|game play]] and inside the [[Search|search]] of a chess program due to [[Reversible Moves|reversible moves]] played from both sides, which might be nullified in one or multiple further reversible moves. The player to move '''may''' claim a [[Draw|draw]] if the same position occurs '''three''' times, or will occur after an intended move, in any order, with the same player to move.
