G'day Ed.
On my P4 1.7Ghz, Crafty finds it at ply 15, with a 96MB hash.
15 2:07 ++ 1. Rxg2!!
15 2:12 7.60 1. Rxg2 hxg2 2. h4 Kb3 3. h5 Kc4 4.
Bg1 Kd3 5. h6 Ke2 6. h7 Kf1 7. Bb6
g1=Q 8. Bxg1 Nc7 9. h8=Q Kxg1
Diep found it at 1 minute, 21 seconds, but then changed its mind. The full
analysis it gave is
