Global Score: 50.83% - NEW RECORD IN MY TESTS

Against
Critter: 52.50% Deep Rybka: 57.19% Houdini 3.0 Pro: 42.81%

This is a new best score for Stockfish in my tests, although only a bit better than the previous best. (16-03-13 got 50.73%).

Only two things to comment:

1.- No one single loss in the 8 matches against Critter 1.6 and Deep Rybka 4.
2.- This is the best result ever against Houdini 3.0 Pro in my tests. In all four legs against H.3 Pro it has scored 40% or more, with an impressive average of 42.81%.

IMHO Stockfish is already the second best engine in the world, only after Houdini.

Regards from Barcelona.

In my dual Pentium PC SF has NEVER won so far 40 games match against Critter. I just finished 60 game match with latest SF version. Level 4m + 0s and Fritz 12 tournament book.

Another good performance against Houdini 3.0 Pro and Critter 1.6. Not so brilliant against Deep Rybka.

How about the Stockfish 120413 used in the current tournament TCEC Stage 4 ?
(I suppose that is the stockfish 120413 x64 SSE4.2.exe compiled by Ipman, but I can't be sure)

This is a good compile. A 43.44% score against Houdini 3.0 Pro after 160 games is a great result. Well done, Ipman & Stockfish Team!.

Tom.

Good result against Critter 1.6, but the strength of Houdini 3.0 Pro pushed the Stockfish score below 40% in their face to face match.
