I have been given the following position as a win for White!
W Kf4 pp f5,g5,h4
B Kd5 pp f6,g7,h7
White to move.
This one is driving me nuts, I can't find anymore than a draw.
TIA.

Looks like a draw to me too.

Are you sure the white pawn is on h4, not h5?

Even draw is not strighforward

The position quoted appears in Muller and Lamprecht's Fundamental Chess Endings, p.38, diag 2.34, as from the game Chigorin - Tarrasch, Ostend, 1905.

They give it as a draw. The bare moves (less analysis) given are:

1. Kg4 Ke4; 2. g6 h6; 3. Kh5 Kxf5 stalemate.

Apparently the actual game went:

1. gxf6 gxf6; 2. Kg4 Ke5; Kh3 Kf4 0-1.

M and L also give 1. g6; h5 and gxf6 (in another variation) as leading to wins for B.

I'll take their word for it.

PS Checking further I find that M and L also have the position in their Secrets of Pawn Endings p82, diag 6.04 where they give a little more explanation but the same moves. Basically, they say that the position usually wins for B but the proximity to the edge of the board allows W to force stalemate.

I didn't consider B trying to win as I was looking for a win for W. But B's K position looks much better. I did consider putting W's K on d5 and B's K on f7. But I think that is still drawn.

Thanks for all the help fellows. I didn't realise what book it came from, one of the kids gave it to me last week at the club and said that he had been told that White wins! It is soon obvious that W doesn't win, and as pointed out, it is one of those nasty ones. If W tries for the win, he loses :) W must play carefully to ensure the draw. Anyhow, your help will allow me to maintain the authoritive teacher role by declaring it a draw with best play by W :)

As I read Muller and Lamprecht, they are saying that the stalemate line they give is the only way W can draw. All other lines win for B.

Don't 1.Kf3 and 1.Kg3 also draw?

It's the same idea Kg4, g6 and then stalemate but it does appear there are 3 solutions?

No. 1.Kg3 h5! - no stalemate.
1.g6 also loses to 1...h5. That's why 1.Kg4 is the only move

OK, no stalemate but after...

1.Kg3 h5
2.gxh6 gxh6
3.Kg4 is still a draw as far as I can see?

This position is in Chessbase's Study Database 2000.

There is no mention of a game reference and just says "Maroczy 1905".
Also there is no mention of 1.Kg3!? or 1.Kf3!?

Only analysis given is..

(Notes by Maroczy)

1. Kg4! Ke5 2. g6! h6 (2... hxg6 3. fxg6) 3. Kh5! Kxf5 (3... Ke4 4. Kg4
h5+ 5. Kxh5 Kf3) 1/2-1/2
