Andernach chess Andernach chess is a chess variant in which a piece making a capture (except kings) changes colour. For instance, if a white bishop on a2 were to capture a black knight on g8, the end result would be a black bishop on g8. Non-capturing moves are played as in orthodox chess. If a pawn captures on eighth rank, it is promoted first and then changes colour.
