Fairy-Stockfish is a chess variant engine derived from Stockfish designed for the support of fairy chess variants and easy extensibility with more games.
It can play various regional, historical, and modern chess variants such as
- Xiangqi
- Janggi
- Shogi
- Makruk
- Crazyhouse
- Atomic
- and many more, including games with user-defined rules
Despite Fairy-Stockfish's generality the playing strength is on a very high level in almost all supported variants, especially when using NNUE. To only name a few it is the world's strongest engine in Janggi, Crazyhouse, S-Chess, etc.
For compatibility with graphical user interfaces Fairy-Stockfish supports the UCI, UCCI, USI, UCI-cyclone, and CECP/XBoard protocols.
