Playing around a bit, I found the following line:
1...Bh4+
2.Rg3 {The second best move, Qg3, leads to Mate in 11 or better} Qd1+
3.Kf2 {forced} Rf8+
4.Qf3 {Nf6+ leads to Mate in 12 or better} Qd4+ {PROBABLY the best move, but not
guaranteed}
This leads to this position:
[D]b4rkr/p1p3p1/1p5p/4p3/2PqN1Pb/1P3QR1/P3PK1P/5R2 w - - 0 5
And White has the option of either Kg2 or Ke1. CM9000, on my humble P3-733,
cannot in a reasonable amount of time find a mate sequence for either of these
moves, so I cannot eliminate either of them. Eval scores for both moves came out
to around -20 after over 20 minutes....
I think that's where the people with the better CPUs are going to need to take
over....
