'''[[Main Page|Home]] * [[Chess]] * [[Moves]] * Reversible Moves'''
'''Reversible Moves''' are all moves by [[Pieces|pieces]] (except [[Pawn|pawns]]) to empty target [[Squares|squares]], thus the complement set of the [[Irreversible Moves|irreversible moves]] of [[Captures|captures]] and [[Pawn Push|pawn moves]] (including [[Promotions|promotions]]). [[Make Move|Making]] reversible moves increments the [[Halfmove Clock|halfmove clock]] inside a [[Chess Position|chess position]] object, concerning the [[Fifty-move Rule|fifty-move rule]].
Reversible Moves in this sense may otherwise not strictly reversible if they lose the [[Castling Rights|castling rights]], that is [[Rook|rook]]- and [[King|king]]-moves from their initial [[Squares|squares]], including [[Castling|castling]] itself. They are irreversible in the sense of reversing the same rights - since once a castling right is lost, it is lost forever, as considered in detecting [[Repetitions|repetitions]]. However, those moves don't reset, but increment the [[Halfmove Clock|halfmove clock]] as well.
