CM9000, on a P3-733, finds Rd3 in 11 seconds, and it eventually gives some of
the highest non-mate evals I've ever seen in a mid-game position, over 22! Where
did this position come from?

Eventually, though, The King (also known as The King of Matefinding) reports
Mate in 11. Any other programs find this?
