I find what you are doing very interesting, not so much concerning the relative strength of Fritz and Crafty, which a series of matches between them can't determine anyway, but regarding testing procedures. I ran 2 similar matches myself between Crafty 17.10 and Fritz 6a in the GUI of Fritz 6a, with the General book of F6 (Alex Kure), tablebases on (2.6 GB of the Turbo CDs) and 4MB hash for each engine. The first match was played on 2 P600E, Game/1 minute, ponder on. The second, on a single P600E, ponder on and game/2 minutes, since each program is using 50% of the CPU. In the first match, Fritz 6a won 15-5, which is consistent with your 14.5-5.5 and seems to indicate that ponder off doesn't hurt Crafty more than Fritz. In the second match, Fritz 6a won also 15-5, which is consistent too, even on one machine and ponder on. Enrique
