For anyone interested in Crafty engines. The Crafty 16.6 has now played 58 games against Fritz 5.32 and Junior 5.0. The score stands as: Junior 5.0 wins 16 to 14 Fritz 5.32 wins 16 to 12 This may not be "Stastically significant" but it's heading in that direction. These games were played at game/60. Crafty used a Pentium II 333 Mhz/128 meg and Fritz/Junior used a K6-2/350 Mhz with 128/64 meg hash tables. Most games were played with Crafty using 96 meg hash,8 meg hasp,10 meg cache. Fritz used 128 meg hash and Fritz used 128 meg with a few games with only 64 meg hash. I have also played a large number of games at game/10. Crafty is not as impressive at this time control but has given Junior 5 a hard time. Scores: Crafty 16.6 wins Comet B00 60.5 to 39.5 Junior 5.0 wins Crafty 16.6 71.5 to 62.5 Nimzo 99 wins Crafty 16.6 52 to 30 Fritz 5.32 wins Crafty 16.6 93 to 39 This indicates that Crafty is only 25 points behind Junior but 150 points behind Fritz. I wish Bob were here to explain why Crafty now plays Junior 5.0 so good now but no improvement shown with games against Nimzo/Fritz(At Blitz). The game/60 results indicate Crafty may play better at the long time controls and should have a chance at time controls closer to tournament conditions. Also I am wondering if this indicates a change in Bob's approach of tuning Crafty to play better comp. vs comp. games vice Crafty vs humans which has seemingly been his goal in the past. Any comments on the above info ?? Jim Walker P.S. I wish Bob was here.
