a chess variant that evolved directly from [[Shatranj]], just like the western [[Chess|chess]]. It is played on 9x9 board.

This leads to the wild, tactical game. Shogi has greater [[Branching Factor|branching factor]] than chess. Development of Shogi programs has taken slightly different route than in chess programming. The stress is on [[Pattern Recognition|pattern recognition]] and [[Selectivity|selective search]] techniques. However, with the advent of [[NNEUNNUE]] <ref>[[Yu Nasu]] ('''2018''').
