Alan, setting your analysis for 60 seconds should yield good results, because the analysis is controlled by ply rather than by time. In other words, if Fritz is in 12 ply after 60 seconds of analysis, it will continue it's analysis through the full 12 ply (which can take several minutes longer). If you set the analysis for 3 minutes per move, you may find that it takes between 24 and 48 hours to analyse a single game. On your machine, 36 meg. of hash should be good for analysis. As for Crafty, based on my experience, I'd say it's about 2400 ELO +/- on a fast machine. It is stronger than many of the commercial programs. Best regards, Brett
