So both Crafty and Ruffian used random values for each game? Or only Crafty?
Obviously you could add that feature in Crafty (if it isn't in there already),
but I had never heard of commercial programs with a feature like that (not
saying they don't exist). Interesting experiment. Do you have any plans to test
Crafty with those winning average evaluation values?
