What Is Komodo Dragon Chess Engine?
Komodo Dragon is a chess engine developed by Komodo Chess, which is a part of Chess.com. It is also known as Dragon or Komodo Dragon. It is a UCI (Universal Chess Interface) compatible engine, which means that it can work with any UCI-compatible chess GUI (Graphical User Interface), such as ChessBase, Fritz, Aquarium, etc.
The History and Development of Komodo Dragon
The original authors of Komodo were Don Dailey and GM Larry Kaufman. Dailey was a computer scientist and chess programmer who created several chess engines, such as RexChess, Socrates, and Crafty. Kaufman is a grandmaster and a former world senior champion who has contributed to the development of several chess engines, such as Rybka, Zappa, and Fritz. Dailey and Kaufman started working on Komodo in 2009, and released the first version in 2010. Dailey passed away in 2013, but Kaufman continued to work on Komodo with Mark Lefler, another computer scientist and chess programmer.
Komodo has won several computer chess championships, such as the World Computer Chess Championship (WCCC), the World Chess Software Championship (WCSC), the Top Chess Engine Championship (TCEC), and the Computer Chess Rating List (CCRL). It has also played against human grandmasters, such as GM Hikaru Nakamura, GM Wesley So, GM Fabiano Caruana, GM Maxime Vachier-Lagrave, etc.
In 2020, Komodo introduced a new version called Dragon by Komodo Chess, which uses NNUE (Neural Network Updated Efficiently) technology. NNUE is a type of neural network that was originally developed for shogi (Japanese chess), but was adapted for chess by Stockfish, another strong chess engine. NNUE allows the engine to evaluate chess positions more accurately and efficiently by learning from millions of games. Komodo has trained its NNUE network based on its own evaluation function, which has a lot of chess knowledge built-in by Kaufman. The result is a huge improvement in strength and style over the previous versions of Komodo.
