ComStock scored 58.30% with 879 wins, 497 losses and 924 draws against the 23 strongest computer chess engines in the 100 round gauntlet matches. The event is category 32 with average ELO rating of 3032. Highest scorers in terms of percent are Houdini 3 Pro x64, Stockfish 3 x64, Robodini 1.1 x64, ComStock 3 x64 and Critter 1.6a x64.
ComStock 3 was released right after the Houdini vs. Stockfish superfinal match at the recently concludedTCEC Live Chess Tournament which was marginally won by Houdini. This was apparently done to satisfy the many spectators who clamor that Stockfish should have the EGTB (End Game Table Base) support that may have altered the outcome of the match.
For those who believed that EGTB support makes the engine stronger or increase the ELO rating, the results below may help dispel that myth. The difference in ELO points between Stockfish 3 and ComStock 3 is 41 points, a huge margin. Other testers may have different results, but my guess is that ComStock 3 will just equal the ELO rating strength of Stockfish 3 at best. The logic is that, the two have 99.99% source code similarity and that the additional EGTB codes that supposedly makes it stronger are actually overhead that waste CPU clock cycles for each call made.
The EGTB was invented to help chess engines find the correct moves in the last phase of the endgame during the time that chess engines have primitive endgame knowledge which made it look like a fool dancing around aimlessly.
EGTB is just a scientific tool to accelerate the completion of the endgame. When both chess engines have EGTB's enabled, the win or draw result is dictated by the actions in the later phase of the middle game. There is no advantage gained in the endgame.
EGTB is good for scientific analysis and probably is also good for cheating, when the other engine does not have EGTB support or is very weak in the endgame.
