Hope they improve the endgame - we really don't need to see three queen promotions - but hey , it's still young and it's already playing at GM level

Perhaps I just missed this info, but

Book (first game in pgn looks like 6 ply?) used?

Network ID used?

Thanks.

Thanks.

Network ID was stated above - 30950.
Book is a hand selected book of 63 positions from Kai’s 3 move opening booking about ~2000 3 movers . Hand selected for positions that have a lesser tendency for draws. It tends to overstate differences between two engines as compared to most opening suites that have more drawing lines. I call this book magic63.epd.

Crafty 4CPU is rated 3056 is the CCRl 40/4, so this would be a performance rating of about 3044. Deep Junior 4CPU is rated 3026, so it appears that would be a good opponent as well. May kick that one off Sunday night (EST), look for a new thread posted.
