'''[[Main Page|Home]] * [[Chess]] * [[Chess Position|Position]] * Halfmove Clock'''
The '''Halfmove Clock''' inside an chess position object takes care of enforcing the [[Fifty-move Rule|fifty-move rule]]. This counter is '''reset''' after [[Captures|captures]] or [[Pawn Push|pawn moves]], and incremented otherwise. Also moves which lose the [[Castling Rights|castling rights]], that is [[Rook|rook]]- and [[King|king]] moves from their initial [[Squares|squares]], including [[Castling|castling]] itself, '''increment''' the Halfmove Clock. However, those moves are [[Irreversible Moves|irreversible]] in the sense to reverse the same rights - since once a castling right is lost, it is lost forever, as considered in detecting [[Repetitions|repetitions]].
