I assume this move wins for white? What is the variation?
Just getting Kf3, my modified Crafty 16.18 does this in 1:46 (less than 2
minutes) at ply 13. This is the variation at ply 14 and 2 1/2 minutes:
14 2:34 6.12 1. Kf3 Bxf4 2. Kxf4 Rd1 3. Kxf5 Rf1+
4. Ke6 Re1+ 5. Kf6 Rf1+ 6. Ke7 Re1+
7. Kd6 Rd1+ 8. Ke5 Re1+ 9. Kd5 Rd1+
10. Kc5 Rc1+ 11. Kd4 Rd1+ 12. Ke4 Kf8
I'll let it run all of today and see what happens.
