At reasonable depths, I get Rf6:
(2) 13 1:14 0.45 1. Rf6+ Kc5 2. d4+ Kb5 3. Kf3 h4 4.
b3 Rc2 5. a4+ Ka6 6. Rh6 Rc3+ 7. Ke4
h3 8. b4 Kb7 9. d5
How long did you search with crafty?
at very shallow depths, I also get rf6. In the 'middle' I get Rxc7 but as it
goes deeper it decides the distant passers are a problem... although I don't see
why white can't play Rxc7, a4, b4 and a5, and at least turn
this into a draw??
