All this with 16MB hash, on an AMD K6/233. Will try the proprietory, WinNT/95 version of Patzer later on... BTW, I should use this opportunity to say out loud, I guess, that Patzer has been doing quite fine on FICS reaching up over 2400 at blitz (it is now only slightly over 2300, due to some time allocation problems) and 2500 lightning (bullet), running on this same machine with only 24 tablebases and 16MB hash. This translates into about 2600 blitz and 2700 bullet on ICC... All this after more than 500 games. Hopefully, lots of useful feedback for Roland. Djordje
