Home * Chess * Moves * Irreversible Moves
Irreversible Moves can not be reversed. Thus, they are either captures or pawn moves [1]. Making those irreversible moves, resets the halfmove clock inside a position object to zero, concerning the fifty-move rule. Quiet and otherwise reversible moves, which lose the castling rights, that is rook- and king-moves from their initial square, including castling itself, are irreversible in the sense to reverse the same rights - since once a castling right is lost, it is lost forever, and reset the position index to determine repetition of positions. However, those "irreversible" moves don't reset, but increment the halfmove clock [2] [3].
