Last night I ran the 2nd 100 games at game/5 minutes between Crafty 16.5 with and without tabelbases in an attempt to determine the value of the tabelbases. It is almost like an instant replay. 2nd 100 games score: First 50 Crafty w/tb +16 =20 -14 = 26 to 24 Second 50 "" " +13 =21 -16 = 23.5 to 26.5 Second 100 games " Total = 49.5 to 50.5 Total for 200 games Crafty with tb =100.5 to 99.5 I only have the 3/4 man tablebases and about 6 of the 5 man tabelbases. Most notably absent is the KRPKR tablebases. I can't generate them on my computer and AOL will not leave me alone long enough to download them. [:-) So far it looks like the tablebases are useless !? I can't believe this though. I really love to see a program announce "mate in 21" when playing 5 minute blitz ! Even if that is the only value I get out of the tablebases I still think they are worth while. I will play a couple hundred more but it looks like the advantage is minimal without the KRPKR tablebase which I believe will yield the most advantage. Jim Walker
