Ke6 Kg8 { The win proceeds in several stages; Stage 1: win Black's RP by K maneuvers alone, making use of king's opposition and shuttle moves. } 2. Kf6 Kh7 3. Kf7 Kh8 4. Kg6 Kg8 5. Kxh6 { Stage 1 accomplished. Stage 2: advance the NP. Black should keep his K in the corner and hope for a stalemate through inattention by White. } 5... Kh8 6. g4 Kg8 7. g5 Kh8 8. g6 Kg8 { Stage 2 accomplished. Stage 3: White brings his K to f7 to control the queening square of the NP, always making sure that Black has an escape route for his K via the R-file! } 9. Kg5 Kg7 10. h6+ Kh8 { If ... Kg8, then 11. Kf6, Kh8; 12. g7+, Kg8; 13. h7+, Kxh7; 14. Kf7 etc. } 11. Kf6 Kg8 12. g7 { Black is now forced to flee to the R-file, away from the defense of f7. } 12... Kh7 13. Kf7 { Stage 3 accomplished. Black can no longer block the promotion of the NP. The rest is elementary. 1 - 0 }
Thanks for helping out. You are right to warn about the stalemates lurking
in there you will be surprised how many Stalemates there have been because
one player was trying to keep both pawns.
In the second example you showed how to tempo Black out of the h-pawn but there is a quicker way to promote.
Here with White to play the simple 9.g7 wns
9.g7 f7 10 Kh7.
The idea I was wanting to get across is that you can sac the h-pawn.
Which will transpose to your game. And add in the mate, correctly done it's only a few moves.
Here with White to play the simple 9.g7 Kf7, 10 Kh7.
Thanks for your comments. The P promotes sooner, as you say, but is the mate quicker if you let the opposing K get away from the edge? Our goal is checkmate, not the Q--a master of annotations taught me that.

How SG can drop a rook and hold off four connected passers to win smacks of voodoo. If we should ever face off, I'm keeping bell, book, and candle at the board!

Have you not read the news? The NSA has direct access to RHP servers--they are dredging millions of chess games, searching for terrorist plots cleverly encrypted as innocuous-seeming chess games. No thanks; I'll keep my privates private and I'll keep my strict neutrality too (= we sell weapons to everyone and their bank accounts stay secret). </sarcasm>
Just to show I can be the sadist as well, here's a more dominant win. (Wonder now that I look at it again if white had better than 28.Qf2, though...) White plays rather aimlessly and I punish it. From another online chess site.

Bc4 Nf6 9. h3 a6 10. Qd2 Qc7 11. Bb3 e6 { to keep pieces out of d5 } 12. O-O { probably the right castling since ...b5 is coming } 12... b5 13. Rac1 { presumably to play Ne2 and c4, but the plan is a bit slow. } 13... Nbd7 14. d5 { Just a bad move. His pawn is frozen on d5 and I get c5 for my N or Q and a 4-on-3 pawn matchup on the K-side. } 14... e5 15. Nh2 Bb7 16. f3 Nb6 17. Bxf6 Bxf6 18. Ng4 { that was a lot of time spent on reaching not such a great square. } Bg7 19. f4 f5 { going for the protected passed pawn. Nice when you get these at move 20. } 20. Ne3 { this N is like the dopey cousin that no one wants to hang out with at family gatherings. } 20... exf4 { changed my mind. white's pieces are poorly organized so I'm going pin-tastic on him. } 21. Rxf4 Bh6 22. Rf3 { Pin #1 } 22... Qc5 { Pin #2 } 23. Kh1 { Pin #2 had to be nullified immediately. } 23... Rae8 24. Re1 Re5 { preparing a new, fun Pin #2 } 25. g3 { trying to restrain ...f4 } 25... Rfe8 26. Ncd1 { you can tell you're in trouble when you're playing moves like this. } 26... Nc4 27. Bxc4 bxc4 28. Qf2 { finally getting out of pin #1 } 28... Bxe3 { cashing in. the 'spectator' Bb7 is going to tip the scales now. } 29. Rfxe3 Qxd5+ 30. Kh2 Rxe3 31. Nxe3 Rxe3 { BAM! 0-1. Neither piece can recapture. } 0-1
