I ran this thru crafty, and got early draw scores, followed by several fail
highs on Kb1.

By depth=25 my score was +1, by 27 it was +1.75.  and by depth 30 it was 3.69...

               30->  48.87   3.69   1. Kb1 Kb8 2. Kc1 Ka8 3. Kd1 Kb8 4.
                                    Ke1 Kb7 5. Ke2 Kc8 6. Kd3 Kd7 7. Kc4
                                    Kd8 8. Kxb4 Ke7 9. Ka5 Kf8 10. Ka6
                                    Ke7 11. Kb7 Kd7 12. b4 Kd8 13. Kxc6
                                    Kc8 14. d5 exd5 15. Kxd5 Kd7 16. b5

Kb1 seems to be the right move...
