'''Shogi''' (Japanese Chess),<br/>
a chess variant that evolved directly from [[Shatranj]], just like the western [[Chess|chess]]. It is played on 9x9 board. Compared to chess, Shogi pieces have limited mobility, but this is compensated by the fact that captured enemy pieces can be [[Piece Drop|dropped]] on the board as one's own. This leads to the wild, tactical game. Shogi has greater [[Branching Factor|branching factor]] than chess. In 2013, the best programs seem at the level of the best human professional players <ref>[http://japandailypress.com/computer-program-defeats-five-professional-shogi-players-2227430/ Computer program defeats five professional shogi players] by [http://japandailypress.com/author/ida/ Ida Torres] - [https://en.wikipedia.org/wiki/Ewdison_Then The Japan Daily Press], April 22, 2013</ref> <ref>[https://en.wikipedia.org/wiki/Computer_shogi#Denou-sen_.282013.29 Computer shogi - Computers versus humans - Denou-sen (2013) - Wikipedia]</ref> .

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.

=Pieces & Moves=
 +
Shogi pieces capture as they move. <span id="Promotion"></span>Promotion is possible with all pieces except King and Gold General - or already promoted pieces with changed move options.
 +
When such a piece moves to, from or inside (but no [[Piece Drop|drops]]) the promotion zone, that is the three opponent's back-ranks, it has the option to promote.
 +
Promotion is mandatory for the forward only pieces of Knight, Lance or Pawn with no more moves after moving to the 9th or 8th (Knight) rank.
 +
Pieces indicate their promotion state by turning the piece over after the corresponding move, revealing the character of the promoted piece. A drop of a captured piece always appears with the unpromoted side up.

Home * Games * Shogi

The starting setup of a game of Shogi [1]

Shogi (Japanese Chess),
a chess variant that evolved directly from Shatranj, just like the western chess. It is played on 9x9 board. Compared to chess, Shogi pieces have limited mobility, but this is compensated by the fact that captured enemy pieces can be dropped on the board as one's own. This leads to the wild, tactical game. Shogi has greater branching factor than chess. Development of Shogi programs has taken slightly different route than in chess programming. The stress is on pattern recognition and selective search techniques. However, with the advent of NNUE [2] along with adaptations of Stockfish to Shogi such as YaneuraOu [3], and Kristallweizen [4], and the consequent Stockfish NNUE hype [5], both worlds seem to reunite again.

Pieces & Moves

Shogi pieces capture as they move. Promotion is possible with all pieces except King and Gold General - or already promoted pieces with changed move options. When such a piece moves to, from or inside (but no drops) the promotion zone, that is the three opponent's back-ranks, it has the option to promote. Promotion is mandatory for the forward only pieces of Knight, Lance or Pawn with no more moves after moving to the 9th or 8th (Knight) rank. Pieces indicate their promotion state by turning the piece over after the corresponding move, revealing the character of the promoted piece. A drop of a captured piece always appears with the unpromoted side up.
