Since you’re here...

We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

Rating

In February 2025, our testers organized chess engine tournaments in which 22,924 games were played. Thanks to this, the ranking is calculated based on 599,651 games!

The list only includes chess engines that have played at least 500 games in our tests.
The game database has been "cleaned" of games that had less than 10 moves.

New chess opening book: M11.2 (bin and ctg)

Image
  We provide two opening books, in two different formats: bin and ctg. This is enough to be used in almost any chess program (GUI). Of course, every book may contain errors, but this one is based on a high rating. Happy testing! Book - CTG format Customers who wish to use the CTG format book will need a GUI capable of reading this format, ie. Chessbase GUIs.  Please save the book in your book folder. We strongly recommend that you "Optimize" the book in the Book options dialog so the tournament moves are chosen. The book is very wide even in tournament mode unlike most other books. A type of book format mainly used by chess programs from Chessbase , such as Fritz, Chess Base, Komodo, FatFritz, Houdini , etc. Book - BIN format (  Used by chess GUIs Arena, Banksia and Droidfish) Binary books have some important advantages, especially for computer chess engines: space-efficient, fast on accessing and searching, more useful information.  At the most simple form, they ar...

Dragon NNUE by Komodo Chess - it's free!

Image
    Dragon by Komodo Chess Larry Kaufman: We have released Dragon 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 is a huge strength improvement over 14.1, the last release, about 197 elo in MCTS mode and 189 elo in standard mode, at CCRL blitz time control on one thread based on direct matches. With four threads, the gains were 156 elo in MCTS and 170 in standard mode. The improvement is due to the embedded neural network providing much more accurate evaluation and also in some sense gaining an extra ply or so of search by “seeing” some tactics that a ...

New version chess engine: Lc0 BT4

Image
LcZero - CEDR Rating=3683 vBT4: Big transformer 4. New network architecture which builds off of BT3 by adding two types of auxiliary heads, future heads and categorical value heads. The categorical value heads predict a distribution over values of q rather than a WDL outcome distribution, and the future heads predict the moves that will be played over the next two plies. The hope is that these heads will give additional information to the net to improve training speed. We've also fixed half-precision training, so this model will be larger. BT4 training started in mid-October and is expected to take a few months. It has 15 layers with 1024 embedding size, 32 heads per layer, and 1536 emb size, for roughly a doubling in size over BT3.  Individual statistics:  Lc0 0.30.0 Stockfish 16 5/13 -3 13 Games Booot 7.2 6/10 +2 10 Games Critter 1.6a 8/9 +7 9 Games Dragon 3.2 4/8 +0 8 Games Stockfish 20230729 3.5/8 -1 8 Games ShashChess 33.2 3.5/8 -1 8 Games Fisherov chess monk 1...

Houdidit 6.03

Image
Michael Byrne: It has been alleged that the chess engine Houdini 6.03 was based on part, the open source chess engine Stockfish. If true, this will allows anyone who purchased the engine access to the source under Stockfish's GPL license. I purchased the engine multiple times over the years and I am now pleased to make the source available to everyone, as it is my opinion that the allegations are true and the evidence provided is overwhelming. In addition, you will find some custom compiled versions of the engine available to all ( allowed under Stockfish's GPL license). The engine here has been renamed to Houdidit , as in guess "Who did it?" and to keep it different from the engine Mr. Houdart was selling which in my opinion was in violation of Stockfish's GPL , i.e, selling Houdini without disclosing it was based, in part, on the open source Stockfish, nor releasing its source. A full discussion of this issue may be found here: http://talkchess.com/foru...
