Houdini 1.01 32 single freaky strong.

[AnthonyTheSage]

I don't know if it can be denied that Houdini is the strongest 32 bit single engine in the world. This is a quick tourney I ran, but the pattern is obvious. All on one thread w/ 64mb hash. Rybka 4 with tc3100100 settings. These i consider to be the three strongest and Houdini is way ahead. Houdini only lost two games in the entire tournament. Rybka and Ivan seem to take advantage of more cores and 64 bit better than Houdini. The race also seem to get tighter with longer time controls. But really neither of those concern me. Most of my pcs are single 32, and most of my analysis is done with ten seconds per move. I personally think long time controls are a waste of time. I want an engine that can think on its feet and give precise analysis quickly. Another thing that is really annoying is all these engines coming out with different settings for playing and analysis. If an engine plays really strong, I want it to recommend the same moves in analysis. But this isn't the case with alot of the top engines. They seem to use different contempt levels for playing and analysis. Thats why I never trust IvanHoe for analysis, I have no clue what settings its using for analysis, and even if they are remotely close to the settings that it uses for playing. Cheers the to Mr. Houdart for the contempt analyze in Houdini 1.02. Also eagerly awaiting the Multi PV in Houdini 1.03.
