Testing stockfish chess3/1/2023 The entirety of chess boils down to evaluating positions, and then searching for good moves. You can find the crosstable and all the PGN games here: Another interesting game lost by ProteusChess v002 against CorChess 3 100122 despite an advantage after opening (complex position) I will publish all LT tournament Proteus Chess SF games. Just challenging my dear friend Mehmet's very strong creature with my ONE MORE Stockfish derivativeĪ draw and a very nice win of Kayra 1.1 (actually #1 on my Group A LT tournament) against Proteus Chess SF v002 (classic evaluation, no NNUE). I will publish all the games In PGN draws the first 2 games against Fat Titz 2 130121 and Kayra 1.1 ) Until now, my bonus pawns modifications to enforce pawn structure seems to compensate well the lack of a neural network. Wow! Disabling NNUE (to use hand-crafted evaluations) Proteus is 3 times faster than the other SF derivative Kayra 1.1 I will release ProteusChessSF under GPLv3 attributing the original source to the Stockfish Team and never share my private engine executable before it will be really different in standard SF playing style.Īt this point, even if the NNUE and MCTS support is available, I'm not interested to the strength but to the style of the engine (I want add positional sacrifices, king safety and castle assault patterns) so hand-crafted evaluation is useful Then I will add hybrid mode.įirst heavy modifications in Pawn Bonus values seem interesting, replaced SugaR 2.50 ICCF (closed project) with ProteusChessSF on my LT tournament On this topic we discuss about how to modify Stockfish to create a DERIVATIVE engine focused on material sacrifices for positional advantage.Īll ideas, suggestions and comments are welcome!
