Revision as of 10:22, 31 July 2020
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-kai [4], and the consequent Stockfish NNUE hype [5], both worlds seem to reunite again.
