Hi Juan Pablo, Thanks a lot for doing these tests! Very interesting. As I write in the Readme.txt file, I am by no means sure that the default settings are the best. I don't think we can draw any conclusions from the games you have played so far, though. With just 24 games for each engine, everything is possible. The most frustrating thing about computer chess is the enormous amount of games you need before you get any statistically significant results. By the way, my guess is that the two "Mobility" settings are the ones which are most likely to be far from the optimal values (simply because my mobility evaluation is new and relatively untested). The "Aggressiveness" and "Cowardice" settings could also be suboptimal, and I think they are more likely to be too high than too low. "Passed pawns" and "Pawn structure" are probably the best tuned of the parameters. Tord
