Fat TIZ engine

Fat Titz 1.0 released
Post by CrapCleaner » 34 minutes ago

This is a FREE UCI-compatibile chess engine. It is a fork of cfish.

https://github.com/Sopel97/FatTitz

Thanks to Norman Schidt and Albert Sliver for inspiration on creating my own fork of Stockfish. Also big thanks to Robert Houdart for great optimization ideas, overall making the engine almost 20% faster!

This engine uses a HalfKAv2-2048x2-64-64-1 evaluation network, which contains whopping 4 times the knowledge of Stockfish 14. It was trained partially on Lc0 data, which gives it a unique positional style, while still preserving the tactical sharpness of Stockfish. The network was trained using a modification of the state-of-the-art NNUE trainer, utilizing publicly available datasets 1, 2, 3

Due to the large size the release is available only on google drive here. It includes Windows and Linux binaries for all supported architectures, along with the network. This is the only place where the network can be found.

You are right Homayoun, this engine it's very strong, i done a tournament and it's was unbeattable by Stockfish 14 and version 21082209, FatFrizt2, Shashchess, Bluefish, Sugar AI 2.30, Corchess and Cfish_13082021.

Thanks for the shared file.

thank you, Hans Obermeier, let's try it.
