If you want try to test any engine by "IQ" test, first try to solve this one.

[pgn] [FEN "rk6/p1r3p1/P3B1Kp/1p2B3/8/8/8/8 w - - 0 1"]
1. Bd7 b4 2. Kf7 b3 3. Ke8 b2 4. Kd8 b1Q 5. Bxc7{#}
[/pgn]

I think that much more than 30 depths for this very easy (trivial) mate in 5, it is too much to run "IQ" test at all.
I really appreciate Sting!

Here is soon to be released SF-McBrain 9.1 with two cores and 8192 hash:
