Wolf chess

Wolf chess (German: "Wolf-Schach") is a chess variant invented by Dr. Arno von Wilpert in 1943. It is played on an 8×10 chessboard and employs several fairy pieces including wolf and fox – compound pieces popular in chess variants and known by different names.
Wolf chess correspondence matches and tournaments have been held, one of which (Paris vs. Augsburg, September 1960) is claimed to be the first international match for a chess variant.
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.
