Wolf chess correspondence matches and tournaments have been held, one of which (Paris vs. Augsburg, September 1960) is claimed to be the first international {{chessgloss|over-the-board}} match for a chess variant.{{sfnp|Pritchard|1994|p=343|ps=}}
==Game rules== As in standard chess, White moves first and the winning objective is checkmate. The king, queen, rook, bishops, and pawns move and capture the same as they do in chess. In addition, there are some special rules.
===Special rules=== * The ''wolf'' moves and captures as a chess rook and a chess knight. * The ''fox'' moves and captures as a chess bishop and a chess knight. * The nightrider moves and captures as a chess knight extended to make any number of steps in the same direction in a straight line. * A sergeant moves and captures one step straight or diagonally forward. A sergeant has the option, like a chess pawn, to move a double-step straight forward (but not diagonally) on its first move. * A pawn (but not a sergeant) may capture an enemy pawn or sergeant ''en passant''. * Pawns and sergeants promote on the last {{chessgloss|rank}} to: queen, wolf, fox, rook, bishop, or nightrider. Pawns (but not sergeants) have an additional option of promoting to ''elephant'' (also called ''amazon rider'' in pocket mutation chess). The elephant piece is not present in the starting setup; it moves and captures as a chess queen and a nightrider (i.e. stronger than an amazon). * There is no castling in wolf chess.
