This maiden release of Honey-XPro is based on the one of strongest chess engines in the world, Stockfish.

Please note that ALL of the strength and usability of Honey-XPro is due to the Stockfish team and to Marco Zerbinati's work in SugaR XPro. The Stockfish team is amazing and they work very hard and are very creative in keeping Stockfish the number 1 engine in the world and all their work is done pro bono for you. So if you have extra CPU cycles sitting around the home or business , please consider donating your spare CPU time:


It is very easy , you can be on any type of OS, Windows/macOS/Linux and they have scripts that will run the process for you behind the scenes, once setup, simply logon to fishtest and leave your computer on.

Honey-XPro will be competitive with any engine at time control of 60 seconds and 2 seconds increment or longer. But the main focus of Honey-XPro is for deep analysis in long games, such as those played in correspondence games.

Future releases will be in alignment with the official Stockfish releases generally, however this will be subject to ELO gains or features added by the SF team as determine by me.

Honey-XPro has been adopted for DGT-Pi electronic chessboard. Please reach out to Al "Scally" Cooper for more information (https://github.com/scallybag) or see download the The Pi exe included here. The setting files that Al distributes have numerous fun and weaker engine settings to play against. Al frequently posts on this site if you want to reach out to him: https://groups.google.com/forum/#!forum/picochess

Finally, a very huge thank you and note of appreciation to Lucas Monge (https://lucaschess.pythonanywhere.com) , John Stanback (http://john.stanback.net) and Dann Corbit (http://rebel13.nl/misc/ebf/dann%20corbit.html) for their work in compiling the different flavors of exe's presented below for Windows and Linux Operating Systems. Hopefully, you find one that works for you.

Honey-XPro also works with the Cerebellum book by Thomas Zipproth (Brainfish Author - www.zipproth.de) . It also includes the standard Honey-XPro UCI options, including Limit Strength (Elo) (use Threads set to 1!) , Brute Force , No Null, Fast Play, Tactical and variety play. All of the keyboard shortcut commands, remain, eliminating the need to always perform the UCI setoption name value command from the keyboard as long as the option name does not contain spaces. As mentioned previously, it accepts 3 polyglot books and will follow the moves of the books in sequential order - play book1 first - once "out of book", twill play from book 2, then book 3 once book 2 is out of book. Honey-XPro-X3 supports 7 man syzygy endgame tablebase.
