FAQ

General

Which executable should I download?

If you just want to make sure it works, use the fairy-stockfish-largeboard_x86-64.exe, which should work on any Windows 64 bit machine. For optimal performance on modern hardware, use fairy-stockfish-largeboard_x86-64-bmi2.exe. If you are only interested in variants on board sizes <=8x8, then use the non-largeboard version, e.g., fairy-stockfish_x86-64-bmi2.exe, which is faster than the large-board version.

What are the correct settings for best performance on my machine?

For playing strength, mainly Threads/Maximum number of CPUs and Hash/Hash-Table size (RAM in MB, e.g., 8192 for 8 GB) are relevant. Set them to the maximum available on your hardware for best performance in analysis (but leave some RAM for OS and other programs). For game play, hash can usually be much lower, depending on the time control (the shorter the smaller).

Which "Skill Level" should I use?

Skill Level 20 means that Fairy-Stockfish plays to the best of its abilities, the levels lower between -20 and +19 are artificially weakened.

Janggi / 장기

Which variant should I use?

• janggi: Tournament rules with bikjang and material enabled.
• janggitraditional: Traditional rules with bikjang ruled as a draw and without material counting.
• janggimodern: Modern rules equivalent to Kakao Janggi, with bikjang disabled and material counting enabled.
• janggicasual: No bikjang or material counting.
