Komodo – Chess Engines – Chess.com

Over the past 10 years, there have been a handful of truly dominant chess enginesKomodo and Stockfish have been battling at the top of the chess engine world since 2013. Let's learn more about the insanely powerful chess engine Komodo.

Here is what you need to know:

Komodo is one of the strongest and most successful Universal Chess Interface (UCI) chess engines on the market. It was originally developed by Don Dailey in 2010 and was further developed by Mark Lefler in 2013. GM Larry Kaufman has been supporting and improving the engine for many years as well.

Komodo was acquired by Chess.com in 2018 alongside the release of Komodo's "Monte Carlo" version. Unlike most conventional chess engines, Komodo Monte Carlo selects its moves by win probability and not with the traditional alpha-beta pruning method. This methodology is similar to the machine-learning chess projects AlphaZero and LeelaChessZero.

Komodo gains an edge over conventional brute force engines because of its positional style of play and the fact that it relies on position evaluation over depthwhen most engines can't find a good plan, Komodo can seemingly create something out of nothing. These are just two of the factors that contribute to Komodo's long-term success and an impressive number of world championships.

Komodo has the ability to run at different playing strengths and with different styles and opening books, which is a very popular feature for chess players. It runs on many platforms including Windows, Mac OS X, Linux, and Android. Although it is a commercial chess engine, earlier versions are free.

Komodo has won many top-level engine championships: CCT15, three Top Chess Engine Championships (TCEC), multiple World Computer Chess Championships, multiple World Computer Blitz championships, and multiple World Chess Software championships. According to the October 2020 computer chess rating list (CCRL), Komodo is ranked third in the world with a rating of 3419.

Stepping onto the scene in 2010, Komodo had its first major success in the CCT15 tournament in 2013 when it placed first with a score of 6.5/7 ahead of Hannibal, Crafty, and 21 other powerful engines.At the end of 2013, Komodo defeated Stockfish in the TCEC season 5 superfinal. In TCEC season 6 it reached the superfinal against Stockfish again (but lost this time). In 2014 and 2015 Komodo again faced Stockfish in the TCEC superfinals for seasons 7 and 8; Komodo won both of these championships.

In 2016 Komodo won the World Computer Chess Championship and the World Computer Software Championship. In 2017 it again won the World Computer Chess Championship and also won the World Computer Blitz title.Komodo repeated as World Computer Blitz champion in 2018 and again won the World Computer Chess Championship and the World Chess Software Championship in 2019.
