Kyoto shogi (京都将棋, kyōto shōgi, "Kyoto chess") is a modern variant of shogi (Japanese chess). It was invented by Tamiya Katsuya c. 1976.
Kyoto shogi is played like standard shogi, but with a reduced number of pieces on a 5×5 board. However, the pieces alternately promote and demote with every move, and the promotion values are entirely different from standard shogi.
