Fritz 7 gets a winning score in less than a minute on an AMD 1.2, but of course
doesn't see the whole mate from move 1. Walking through with it, the best I
could do was a mate in 31:
1.Be2+ Ke1
[1...Kc1 2.Rc4+ Kb1 3.Bd3+ Ka1 4.Rc2 Kb1 5.Rb2+ Ka1
(5...Kc1 6.Rb1#)
6.Rb1#]
2.Bg4+ Kf1 3.Bh3+ Kg1 4.Rg4+ Kh1 5.Bg2+ Kg1 6.Bxb7+ Kf1 7.Ba6+ Ke1 8.Re4+ Kd1
9.Be2+ Ke1 10.Bg4+ Kf1 11.Bh3+ Kg1 12.Rg4+ Kh1 13.Bg2+ Kg1 14.Bc6+ Kf1 15.Bb5+
Ke1 16.Re4+ Kd1 17.Bxa4+ Kc1 18.Rc4+ Kb1 19.Bc2+ Kc1 20.Bf5+ Kd1 21.Bg4+ Ke1
22.Re4+ Kf1 23.Bh3+ Kg1 24.Rg4+ Kh1 25.Bg2+ Kg1 26.Bc6+ Kf1 27.Bb5+ Ke1 28.Re4+
Kd1 29.Kb2 Rxc5 30.Ba4+ Rc2+ 31.Bxc2#
I guess I need to shorten this by 6 moves. Hmmm...
