|Stockfish Polyglot: Updated July, 23 2020|
For Windows only, NO LINUX, ANDROID OR MACOS!
Changelog: Matching Stockfish beta having timestamp 1595010524 - Do not overwrite valuable TT data after probcut.
July, 12 2020: The source code on GitHub has been updated https://github.com/massimilianogoi/Stockfish-Polyglot. I would appreciate if someone is so nice to build the Android version.
The new thing on this Stockfish Polyglot is that I've set back the contempt as 24 for experimental purposes. It seems to behave very well. Because of the active contempt I preferred to remove it from the analysis engines because this parameter produces fluctuations in the evaluations.
Stockfish Polyglot is the same Stockfish with the ability to read Polyglot books (.bin format).
This chess engine can read up to four Polyglot books.
This distribution is enhanced by the pgo-build option. Stockfish Polyglot automatically detects your maximum number of threads and set it as default value in the UCI settings.
Stockfish Polyglot comes with almost any architecture available, hence also for old 32bit operating systems like Windows XP, old machines, 64bit systems, standard machines, modern machines and power computers. It runs on Windows only this time.
