Fat Titz, (FatTitz)
an UCI compatible chess engine by Tomasz Sobczyk, a fork of CFish, and a pun of Fat Fritz 2, the commercial derivative of Stockfish 12. Fat Titz 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 [2], utilizing publicly available datasets [3].
