How strong are the best computer chess engines?

Stockfish DD, ELO 3247 Stockfish is the most powerful, free, open source chess engine in the world. Rated only 20 ELO points below the top commercial chess engine Houdini 4, Stockfish is definitely a great alternative for most chess players. Stockfish plays better and faster than humans.

Chess.com is pleased to announce the Chess.com Computer Chess Ratings. These ratings are calculated based on performances in the Chess.com Computer Chess Championship, Chess.com's 24/7 computer tournament platform where the best engines are constantly battling. To ensure accurate ratings, we conducted a benchmarking tournament under the Computer Chess Rating List (CCRL) conditions which included engines from the CCRL blitz rating list running on 4 CPUs and the current Ethereal engine, running on our hardware with 90 CPUs. Ethereal scored a performance rating of 3578. All ratings are then derived from performances in this event.

1. Download free Chess Engines Chess engine is the unique software which is built into the program shell (e.g. 'Fritz', 'Arena', 'Shredder') thus multiplying the force of the game shell. For example, 'Kasparov Chess' is very good and clever shell. The maximum rating which can be set in it is 2600. And the rating of the chess engines reaches 3000-3200.
2. Engines - You may not use any engines to help solve tactics! This includes Chessmaster, Fritz, Komodo, Houdini, Stockfish, Chessbase with any active UCI engine, etc. Tablebases - Tablebases are chess databases that contain every possible move for endgames of up to 7 pieces. These will always lead to a win when a win is possible, and are for.
3. There are many chess engines oout there, and the best one for you depends on what you want to use it for. If your want to use it to analyse your games, any engine above 3000 rating will be strong enough.
4. It is influenced by open source engines IPPOLIT/RobboLito, Stockfish, and Crafty. Earlier versions are free for non-commercial use (up to version 1.5a), but later versions (2.0 and onwards) are commercial. As of January 2017, Houdini 5 is the second top-rated chess engine on major chess engines rating lists between Stockfish and Komodo.

Ratings will be released on the 1st of each month and will be based on games played in the last 60 days. Given rapid developments in computer chess, multiple development versions of engines may have competed in the rating period. Consequently, we caution readers not to interpret these ratings as being the most accurate estimate of each engine's strength. Usually, such estimates are achieved through careful benchmarking by the development team. The Chess.com Computer Ratings are most useful for providing insight into the relative performance of all competing engines in the Chess.com Computer Chess Championship.

Best Chess Engine

Our inaugural rankings include both Stockfish and Stockfish Classic, acknowledging the significant development of NNUE technology which incorporates a neural network evaluation into traditional brute-force engines. The most recent releases of Stockfish with NNUE top both our blitz and bullet lists, while the latest version of Stockfish without NNUE still ranks highly and is retained separately on our list for comparison purposes.
