Komodo CCT x64 - Gauntlet Matches 100 Rounds

Komodo CCT x64 by +Don Dailey and +Larry Kaufman scored 55.33% with 971 wins, 715 losses and 714 draws in the 100 rounds gauntlet against the 24 strongest chess engines in the world. Komodo acquired 3069 ELO rating, placed #11th in the gauntlet and #7 in the 100 Top Chess Engines list. It gained 33 ELO points from the previous version.

Komodo CCT was the the winner in the 15th CCT World Computer Chess Championship and was famous in the recently concluded TCEC live chess championship where it reached the semi-finals against the most formidable opponents like Houdini, Stockfish and Rybka. It was amazing that Komodo was able able to face them squarely even though it was just single core against opponents that can take advantage of 16 cores. It was like boxing with just 1 hand against foes with 16 hands!

The event raise doubts about the merit of very powerful computers with massive cores in chess engines competition. It showed that there is only a small gain for each increase of CPU core. In a competition with just 1 core CPU, Komodo is in the league with the top 5 strongest computer chess engines.
