:安南将棋 annan shōgi)
also called Korean shogi, is a variant
(Japanese chess). Annan shogi is a popular shogi variant in Japan.
The game is played as standard shogi, except that, when a piece has a friendly piece on the square directly behind it, it has the movement of that piece instead of its own. A variant rule is that a piece may move like any friendly piece that protects it.
The game should not be confused with Korean chess, a variant of chess that is played in Korea, but which resembles xiangqi (Chinese chess) rather than shogi.
