'''Fat Titz''', (FatTitz)<br/>
an [[UCI]] compatible chess engine by [[Tomasz Sobczyk]], a fork of [[CFish]], and a pun of [[Fat Fritz#Fat Fritz 2|Fat Fritz 2]], the commercial [[:Category:Derivative|derivative]] of [[Stockfish|Stockfish 12]].
Fat Titz uses a [[Stockfish NNUE#HalfKA|HalfKAv2-2048x2-64-64-1]] [[NNUE|evaluation network]],
which contains whopping 4 times the knowledge of [[Stockfish|Stockfish 14]].
It was trained partially on [[Leela Chess Zero#Lc0|Lc0]] data, which gives it a unique positional style,
while still preserving the [[Tactics|tactical sharpness]] of Stockfish.
The network was trained using a modification of the state-of-the-art NNUE trainer <ref>[https://github.com/glinscott/nnue-pytorch GitHub - glinscott/nnue-pytorch: Stockfish NNUE (Chess evaluation) trainer in Pytorch]</ref>,
utilizing publicly available datasets <ref>[https://github.com/Sopel97/FatTitz GitHub - Sopel97/FatTitz: A chess engine based on cfish]</ref>.
