With White to play? Yes.

1. Kh6 wins:

1...Kh8
2. g6 Kg8
3. g7 Kf7
4. Kh7 and the Pawn will queen.

Or

1...Kf7
2. g6+ Kf8
3. Kh7 Ke7
4. g7 etc.

Or

1...Kf8
2. g6 Kg8
3. g7 Kf7
4. Kh7 etc.

[My original source for this position gave 1. Kf6 as White's winning move. This is incorrect, as Black can draw (as has been spotted) with 1...Kh7. 2. g6+ Kh8 3. g7+ Kg8 (or 2. Kf7 Kh8).]

With Black to play? Yes.

1...Kf8
2. Kh7 Kf7
3. g6+ and so on to queen.

Or

1...Kh8
2. Kf7 Kh7
3. g6+ etc.

Generally, in endings with King and Pawn against King, if the side with the Pawn can achieve this position, the Pawn may be shepherded safely to the queening square, whoever has the move.

Maybe we should just make one principle based on this: the pawn will queen [provided he doesn't commit a blunder] if the White King reaches the 6th rank (in front of the white pawn) with or without the opposition.

Not with a or h-pawn.

But Kf6 would appear to win by transposition into the Kh6 lines via 1..Kh7 2.Kf7 Kh8 3.Kg6 Kg8 4.Kh6 etc. However as indicated if White plays 2. g6+ then the win is thrown away. This type of manoever is known as "Triangulation". There is a good article on it here:-

True. But it could hardly be called the "winning" move. And to avoid going around in circles, White must play Kh6 at some point...

I'm trying to keep everything straightforward for the benefit of those willing to learn something. The solution given in my original source should be regarded as an error.

there r 2 reasons why nobody less than 1600 posts the results here...
1. We need more time to solve these "lessons"
2. If we could actually find such brilliant solutions we wouldnt be under 1600 anyways... 😛
Bowmann, keep them coming....maybe someday i will beat propawnkiller to it. LOL 😀

Perhaps if those with ratings above 1600 could stop jumping in as though it were some sort of competition, you might have a chance 😉

And yet, these aren't tests as such. Just so long as you understand the principles involved in each example, even after they've been "solved".

When I open the lessons, I make my window smaller so I can only see the initial problem post. I then post my answer without looking at the other solutions. I presumed other people were doing the same.

I don't see the point in reading posts after a problem unless you don't want to solve the problem.

I am in a game where I have a game that delivers a good lesson about the importance of a single pawn. It's a draw. White has a Queen and a King. I have a pawn and a king. I'm playing the game at present. My Russian protege will not see that is a draw. He is sad to draw. The White Queen must continue to check, or the black pawn advances, or he can choose a stalemate. I'll post that endgame from this RHP game soon enough. I am so proud to draw this 1570+ player from Russia. 🙂

This brings new meaning to "pawns of power" eh?

Is it a bishop's or a rook's pawn?

I don't want to say until the game is over. I don't want to be blamed for discussing games again even if I'm not. But, we're still playing this game, and it's past 70 moves. Please do not look at my archives and discuss this game! Thanks! And, after analyzing this game again, I believe there might be a zugzwang mate... with White somehow making a waiting move, and forcing the king away from the pawn and capturing it. After this game is over, I would like to discuss the endgame part in this forum. Maybe we can all learn something frmo it. 🙂 It's very instructional!
