Good but not great performance for Stockfish in the two latest development versions. I will retest the best performing version in my tests so far: 140913. Bench: 3846852 Timestamp: 1379156917. Let’s try to reduce the statistical noise.

Regards,

Tom.

In an attempt to minimize the statistical noise, I have retested SH 140913 version.

Still above Houdini 3.0 after 960 games. I have just started the third and last 480 games test of this version. The strongest one of Stockfish in my tests till now.

Estimated ELO performance= 3,175

-------------------------

After three tests including 1.440 games, Stockfish 140913 remains somewhat ahead of Houdini 3.0 Pro. Only 3 Elo points in the global estimate (Not relevant. Still within the statistical noise range, despite the number of games), but a more relevant 52.81% score after the 480 games played one–to-one. What a pleasure watching these top level games!.

Under my test settings environment, I can confirm that this is the best Stockfish version so far. I am sure that new improvements will appear soon. Well done, Stockfish TEAM!.

Tom.

This is an EXCELLENT performance, with an Estimated ELO 11 points better than Houdini 3.0 Pro and a clear win in the four face-to-face legs. I will keep testing this compile until 1.440 games, to minimize the statistical noise.

Congratulations again to Stockfish Team for their great work. And thanks to Ipman for this fast compile. I find all this Stockfish development really fascinating.

Regards,

Tom.
