I still can't get a white win. But underpromting is the only option so far that's playable.

At the time I suggested 6...fxg6 it was not a blunder. It was the only legal move. I was still on this line:

1. h4 Kc7 2. h5 Kb6 3. h6 a6 4. h7 Ka5 5. h8=N b6 6. Ng6

I'm currently, in the newer line, in which Black holds the pawn at b7, right about here:

1. h4 Kc7 2. h5 Kb6 3. h6 a6 4. h7 Ka5 5. h8=N Kb6 6. Nxf7 Kc7 7. Ne5 Kd6 8. f7 Ke7 9. Kc2 a5 10. Kb2 a4 11. Ka2 a3 12. Kb1 b6 13. Ka2 Kf8 14. Nd7+ Kxf7 15. Nxb6 Ke6 16. Nc8 Kd5 17. Na7 Kc5

... and I am of the reformed opinion that Black can, in fact, force the draw. I can't see any way for White to progress. Black's king will keep the knight at bay.

White can win if blacks king gets to f8 and then white promotes the h pawn to a queen then checkmate.

Kf8 h8=Q Checkmate.

Then again, 14. Nd3 might improve things to a win for White ...

Yeah, I think White wins. But not easily 😀

Black is not forced to push his a-pawn.
He can shuffle his king between e7 and f8.
[Edit: Corrected c8 to f8.]

You must mean e7 and f8. Give me a minute on that one ...

I relent:

1. h4 Kc7 2. h5 Kb6 3. h6 a6 4. h7 Ka5 5. h8=N Kb6 6. Nxf7 Kc7 7. Ne5 Kd6 8. f7 Ke7 9. Kc2 Kf8 10. Kb2 Ke7 11. f8=Q+ Kxf8 12. Nd7+

... and White will, at best, end with K+N against K for a draw (for example: 12...Ke7 13. Nc5 a5 14. Nxb7 a4 15. bxa4 bxa4 16. Nc5 a3+ 17. Kb3 Kd6 18. Nd3 Kd5 19. Nxb4+ Kc5 20. Kxa3).

I think my final answer is: Black draws. But not easily 😀

Agreed. If there is a way for white to win this I can't find it. MUCH MUCH harder than it looks at first. Hence the reason it's a "puzzle" I suppose. 🙂

Anyway, I give up.

Does anyone in this thread have fritz? If so slap this puppy in there and see what it says.

Whats wrong with this:

Following the others line with 7. Ne5 Kd6 8. f7 Ke7 9.Kc2 Kf8 10. Kd3 and then moving the king to f6 or g6. For me it just looks like white wins, he will get a queen before black will.

Good work Rag.
