I think white can win by stalemating the black king (kings on a8 and c7)and thus forcing a5, then replying to that with b5. Will at the least coronate the b pawn with check and well before black can do the same.
For instance 1. Ke7 Kb8 2. Kd7 Ka8 3. Kc7 a5 4. b5 wins.
Of course black need not go to the corner if he sacrifices the a pawn before the stalemate when the white king would not support the b pawn, but then after taking white wins by playing a6 at a suitable moment, when he can answer bxa6 with Kxc6, then king being on the d-file. A position with black king on b7 and pawn on c6 and white king on d6 and pawns on c6 and c5 is easily winning since quickly white wins the last black pawn.
white wins as his king can back black’s king in the corner and force the advance and loss of black’s a pawn.
White wins, but not because he can force the loss of black’s pawn.
1. Ke7 Kb8
2. Kd7 Ka8
3. Kc7 a5
4. b5 c4xb5
5. c6 b7xc6
6. b7+ Ka7
7. b8Q+ and mate in 2.
Other moves that black could make only give up material on the way to the same result.
Ke7 wins for white.
White wins with 1. Kd7. The most amusing variation (to me at least) is:
1. Ke7 Kb8 2. Kd8 Ka8 3. Kc8 a5 4. b5! cxb5 5. c6 bxc6 6. b7+ Ka7 7. b8=Q+ Ka6
8. Qb7# 1-0
White wins by sacrificing two pawns. Here’s a possible continuation:
1. Ke7 Kb8
2. Kd8 Ka8
3. Kc8 a5
4. b4 cxb
5. c6 bxc
6. b7+ Ka7
7. b8=Q+ Ka6
8. Qb7#
the loss of the a-pawn would still be a draw.
the win is achieved by advancing the b-pawn b4-b5! as reply to blacks a6-a5. then eithet cxb, c5-c6 or a5-a4, bxc wins both for white
It is a draw. If King is forced to stay at corner and move a pawn then it is stalemate.
It’s a win. My mainline goes 1.Ke7 Kb8 2.Kd7 Ka8 3.Kc7 a5 4.b5! (not bxa5 stalemate!) cxb5 5.c6 bxc6 6.b7+ and wins. Nice breakthrough.
It’s not the loss of the a-pawn, it’s the clearing of defender of b. After B plays a5, W plays b5 and rolls up the pawns
White wins after: 1. Ke7 either black has to move his a-pawn or back up the king allowing white’s king to penetrate the position and support his pawns.

bxa5 stalemate
..which would be stalemate, draw I think, but I said that yesterday and it was a white win 🙁
@jumpin joe
Wouldn’t taking the a pawn be a stalemate?
Rather force the black king in the corner to make black move the a pawn but bypass with b5. If black takes on b5, you’ll get two white pawns on b6 and c6 against one black pawn on b7. Next check on b7 and promote a queen with a win.
If black does not take on b5, you’ll take on c6 with similar position.
Wrong again lol, just noticed the really obv double pawn sac to free the b-pawn, white wins easily
1. Ke7 Kb8
2. Kd7 Ka8
3. Kc7 a5
4. b5! cxb (a4 5. bxc6 a3 6. cxb7+ and wins)
5. c6!! bxc
6. b7+ and wins
king into corner
black moves a6-a5; then b5-b6! wins
1.Ke7 Kb8 2.Kd7 Ka8 3.Kc7 a5 4.b5! cxb5 5.c6! bxc6 6.b7+ 1-0
Really,
but what happens after white has grabbed the pawn ?There will be a stalemate, right (the same situation that forced black to move his pawn will give him the draw !?).
So i’d say this is draw.
Its a draw. (or loss for white)
When locking in black king on a8 black is forced to play a5. Then white must play bxa5 and there will be stalemate.
white wins with:
1.Ke7 Kb8
2.Kd8 Ka8
3.Kc8 a5
4. b5 cb5
5. c6 +-
or
1.Ke7 a5
2.ba5 Kb8
3.Kd8 Ka8
4. a6 ba6
5.Kc8 +-
I agree white wins. I see no win for black, no draw. Ke7!
