Here is the solution to this difficult puzzle:
1. Bg2 Kg7 2. Be4 Kxh8 3. Bxg6 hxg6 4. g5 Kg7 5. Kxc4 Kf7 6. Kd5 Ke7 7. Ke5 Kf7 8. Kd6 Kf8 9. Ke6 Kg7 10. Ke7 Kg8 11. Kf6 Kh7 12. Kf7 Kh8 13. Kxg6 Kg8 14. Kh6 Kf7 15. g6+ Kg8 16. g7 Kf7 17. Kh7 1-0
White to move. Is this a win or draw? How should White proceed?

It’s a win for White but I’d have never figured it out without my computer.
Now that I know the key move that leads to a winning King and pawn endgame, I might be able to find the solution if a similar position came up in the future.
Bf1
Whithe wins of course!
Nxg6, hxg6
Bg2, Kg5
Bf3, Kf4
Bd1, Kxxx
and white king beats the black pawns Kxc4 and WIN! Of course, there will be obligatory move of black king to leave his last pawn on g6…..
The main variation is :
1.Bg2 Kg7 2.Be4 Kxh8 3.Bxg6! hxg6 4.g5 Kg7 5.Kxc4 Kf7 6.Kd5, winning
on 1..g5 white can play 2.Be4 Kg7 3.Bxh7
on 1..h5 2.gxh5 gxh5 3.Be4 etc.
But what if Nxg6 Kxg6 and then black push h4? White has no pawns then.
How about 1. Nf7 Kxf7 2. g5.
I think that ought to do it for white.
