Your hours of tinkering paid off as your compile is 4.2% faster then Aaron's and
5.5% faster then Byrnes' and Skinner's. After testings Aaron's version on line
it appears to only push the CPU to an average of 96% during games (Byrne's and
Skinner's average 98%). I will test yours further today and let you know the
results during game play. Also it should be noted that yours and Aaron's compile
did not use the -DFAST option for the compile. This can slow things down abit
due to other calculations Crafty does if this option is not used at compile
time.


Tests run on a Athlon 3000+ system under WindowsXP default hash settings.
