I just played a 1031 game match between ColChess (development version) and Crafty v17.4 and the final score was Crafty won 966, drew 54 lost 11.
The games were 10 minute blitz games and it took a week to play (I just left my computer running while I went home for a week

Basically, Crafty has built up a very large learning file and now it seems wise to all ColChess' tricks. I might run the tournament again, or at least a fairly large one, but without Crafty's learning book.
By my calculations that gives a pretty good estimate for our rating difference at blitz/10 as 567 ELO points, which is still a little too high

Anyway, thought you might be interested just for humour value.
Cheers,
Colin
