Here's one that The King doesn't do well on. Even after forcing the moves all
the way through 5...Kh3, it still takes CM9_R1 1:24 on a P4-2.4 to find the
critical move 6.Bg3+. It announces Mate in 10 sixteen seconds later, at 1:40.

So I tried it with TK 3.33 from CM10th, with the default settings (which is
probably not a fair comparison). It took even longer -- 2:09 to find 6.Bg3+, and
took more than five minutes before it announced Mate in 10.
