After a reasonable amount of time, crafty sticks with the following (it likes
this move from the get-go and never changes):

               12    39.45   0.62   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 a5 5. Rc7+ Kd4 6. f6 Ra1+ 7.
                                    Kh2 Ra2+ 8. Kg3 Ra3+ 9. Kg2 e4
         (2)   12->  47.03   0.62   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 a5 5. Rc7+ Kd4 6. f6 Ra1+ 7.
                                    Kh2 Ra2+ 8. Kg3 Ra3+ 9. Kg2 e4
               13     1:05   0.60   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 e4 5. Re7 Kd4 6. f6 Ra1+ 7. Kh2
                                    Ra2+ 8. Kg3 Ra3+ 9. Kg2 e3
         (2)   13->   1:51   0.60   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 e4 5. Re7 Kd4 6. f6 Ra1+ 7. Kh2
                                    Ra2+ 8. Kg3 Ra3+ 9. Kg2 e3
               14     2:34   0.76   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 e4 5. Re7 Kd4 6. f6 Ra1+ 7. Kh2
                                    Ra2+ 8. Kg3 Ra3+ 9. Kh4 a5 10. Rd7+
                                    Kc3
         (2)   14->   3:51   0.76   1. Rb7+ Kd6 2. Bxc5+ Kxc5 3. Rxg7 Rxa4
                                    4. h3 e4 5. Re7 Kd4 6. f6 Ra1+ 7. Kh2
                                    Ra2+ 8. Kg3 Ra3+ 9. Kh4 a5 10. Rd7+
                                    Kc3

It's a bit more double-edged than trying to pick up the a pawn...
