    Fisherov - UCI chess engine (NNUE) Rating JCER = 3507 (1 place) Meaning of the name: Fisherov = Stock"fish" + Fisch"er" + Kaspar"ov".  Fisherov is a chess engine derived from stockfish. Code has been added in various parts to achieve a different style, which becomes more evident by deactivating his neural networks (although this would cause him to significantly lose his strength but he would gain in aggressiveness, which would be interesting for human training or to make him compete against other non-neural chess engines). For greater robustness and competitiveness, the use of a neural network must be left activated (as it already comes by default). The engine already has a network incorporated, although there is also the possibility of using another network from the UCI options. This engine was developed by Luis Damián Primo and Andres Ivan Primo. Hope you enjoy. Fisherov 0.98k download -  Engine is not publicly available and is non-commercial The Fi...

Avalanche - UCI (NNUE Chess Engine) Author: SnowballSH  Rating CEDR=2638 v.0.2.2: This release improves TT and LMR, as well as adding Aspiration windows. It seems to be 70-150 ELO stronger than 0.2.1 based on 100 STC games. Avalanche 0.2.2 NNUE download

BrainLearn - UCI chess engine Rating CEDR=3479 BrainLearn is a free, powerful UCI chess engine derived from BrainFish. It is not a complete chess program and requires a UCI-compatible GUI (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. Read the documentation for your GUI of choice for information about how to use Stockfish with it.  v.17: Aligned with stockfish patch Negative extension for ttMove that is less than alpha and value in the context of singular extensions Individual statistics BrainLearn 15.2 - 76 games (+ 16,= 59,-  1), 59.9 % Cfish 290721                  :   2 (+  0,=  2,-  0), 50.0 % Komodo 12.1.1                 :   2 (+  1,=  1,-  0), 75.0 % Bluefish 180921               :   2 ...

Rebel - UCI engines Rating CEDR=3139 (27 place)  Thanks to the author : Ed Schroeder  Website    v.15: 👉 New and stronger neural network made from 1.87 billion positions. 👉 Estimated strength increase over Rebel 14.2 emulating CCRL 40/2 testing in the range of 80-130 elo. 👉 NNUE tuner parameter in Engine Settings. Default setting now 70%. 👉 For the moment Rebel 15 is only available as AVX2 engine. It has to be seen if we are still able to provide a weaker SSE version for older computers. NNUE evaluation strongly relies on the AVX2 instruction set and there might come a moment older computers become an obstacle to progress.

  About Us by GM Larry Kaufman Komodo started in 2007 as a joint project by programmer Don Dailey and myself, grandmaster Larry Kaufman, when I was a member of the team that created Rybka 3, then the world's strongest chess engine. It was then called "Doch" as an abbreviation for "Don's Chess", but we learned that this name is not suitable in the German language, and I suggested the name "Komodo", both because the Komodo Dragon is the world's most fearsome lizard, and because "Dragon" suggests the Dragon Sicilian, a popular fighting opening. At the time it was mostly just for fun and as a learning experience for me; we never expected it to be a rival for Rybka, but things turned out differently. More and download

Dragon 3.0 GM Larry Kaufman will introduce Dragon 3 by Komodo Chess. We have released Dragon 3 at komodochess.com. Dragon uses NNUE (Neural Network Updated Efficiently) technology, originally developed for the game of shogi. Komodo has a great deal of chess knowledge in its evaluation. Training an NNUE network based on this evaluation was both an advantage and a challenge, requiring experimentation with architectures and data generation of billions of positions. The reinforcement learning phase for Dragon is in its infancy, but is already showing great promise. Dragon 3 is a huge strength improvement over Dragon 2, roughly 80 elo at blitz on eight threads and 107 elo on one (using normal openings), about 132 elo in MCTS mode, and 148 elo when playing Fischerandom (chess960). It is a significant improvement over Dragon 2.6.1, about 17 elo on one thread blitz, about 20 elo in MCTS mode. The gains over Komodo 14.1, the last pre-dragon release (Nov 2020), are in the 300 to 400 Elo range on...
