Komodo TCEC x64 - Gauntlet Matches, 100 Rounds

Komodo TCEC x64 is a UCI chess engine by Don Dailey, Larry Kaufman and Mark Knofler released last December 4, 2013. It won the recent prestigious TCEC Live Tournament ahead of Stockfish and Houdini, just a week after the principal author Don Dailey passed away.

Komodo TCEC scored 62.7% with 870 wins, 362 losses and 768 draws against the top 20 strongest chess engines.  It garnered 3173 ELO rating points and number 3 in the Top 100 Strongest Computer Chess Engines list.

Based on forum postings from the authors, Komodo was designed for positional play which was best suited in competitions with long time controls. The proof was its unexpected victory in the TCEC Live Tournament with conditions that suit the style of play of Komodo.

Most computer chess rating list sites have Komodo in number 2 or 3 rank with a wide gap of ELO rating in between the number 1.  These are sites which normally use the fast blitz speed that favors Houdini and Stockfish. In this rating list site, Komodo TCEC only managed to maintain its number 3 rank below Stockfish DD and Houdini 4 Pro with only 34 ELO points increment from the previous Komodo 6 version. It needed a strength of 45 ELO points more to be the number 1.

Here is the gauntlet performance of Komodo:
