Cheers, I have just downloaded that one and it has already beaten the best version I found!
I'm new to this but I usually do a blitz game with a 5 minute time limit and 5 matches
then I do matches with 7 seconds allowed per move. 4 cpu and around 2000mb hash tables, ponder off
they alternate black and white every time.
I'm not sure I have the right version of houdini 4 though because it loses badly most of the time lol
