I think this is the real Yokohama.

Undoubtedly the strongest tournament in computer chess ever, considerably stronger than the Houdini-Cluster Rybka match.

Game 6 is a foretaste of how I see computer chess in 10 years' time.

Is split depth=12 really best for Houdini running 8 threads? It seems rather high to me, based on testing with Stockfish and Critter.

I will predict Stockfish 180813 will win this tournament, my early testing suggest at faster time controls. Stockfish 180813 has surpassed Houdini 3, and Houdini 3 may no longer be the strongest chess engine. I doubt a longer time control on much faster hardware will change the results, going by past Stockfish testing.

It will be interesting to watch...

At what level "faster time controls" and with how many cores did you test? Have you run a significant number of games? At bullet speeds, the latest SF still lags behind Komodo 5.1r2 by about ten elo based on 2k games, and of course in bullet chess Komodo is no match for Houdini 3. Since both Komodo and SF gain on Houdini with increased depth, this should be a pretty close contest.

I played 40 games of 40/3mins. In a head to head match Houdini 3 Vs. Stockfish 180813. Stockfish won by 62.5%

Stockfish has only been out for a short time, but I ran this test to see if this version was worth further testing. With that score, and a LOS of almost 95%. It is worth testing further, as either Stockfish was very lucky, or it is better. The results could be wrong as you know in this kind of quick test, but the odds are it is ok to make my prediction with this little evidence, since Stockfish in the past plays even better with more time.

That is why I used the word suggest, as this is only my prediction and why. I don't have a LOS of 100%, but unlike past stockfish versions, it will not take a huge number of games to show superiority with a win % close to 60. If it can maintain that kind of edge in further testing. I will know more in a few days, doing a ratings test now with all top programs at 40/10mins.

I ran my quick test on a i7 CPU, with 4 cores, ponder off, 512 mb hash. Same opening book of GM games to 6 moves. Each program plays the opening with both colors.

in autotune SD 10 was 16624kNs and Sd 12 was 16738kNs so I decided to use SD12

Hi All

half of the tournament is done now.

Stockfish is a little behind Houdini and Komodo, but there are still a lot of games to play.
Good luck to the 3 Champs for the next half of the tour!
