White should try to end up in a position where is extra pawn is behind his king, so that the king can gain the opposition.
I first saw :
1. Kb4 c5+!
2. dxc5 Kc6
3. c4 d4! but could find a way forward for white.
I think this should do :
1. c4! c5
2. dxc5+ Kxc5
3. cxd5 Kxd5
4. Kb4 Kc6
5. Kc4
and white can gain the opposition.
1. c4! dxc4
2. Kb4 c5+!
3. Kxc4! cxd4
4. Kxd4 Kc6
5. Kc4 is the same.
Kb4 White win+
1.Kb4 c5+
2.Ka4 cxd4 (2…Kc6 3.Ka5 results in the same)
3.cxd4 Ka6 4.Kb4 Kb6 5.c3 Kc6 6.Ka5 Kd7 7.Kb5 Kd6 8.Kb6 Kd7 9.Kc5 Ke6 10.Kc6 Ke7 11.Kxd5
Can’t see a reason why white should not win this?
1. Kb4 Kb7
2. Kc5 Kc7
3. c4 dxc4
4. Kxc4 Kd6
5. c3 Ke6
6. Kc5 Kd7
7. d5
This should be a win for white. Move the c-pawn up to c4, or the king to b4. Exchange the c- & d-pawns. Advance the remaining c-pawn along with the d-pawn. Should be a win.
