Endgame study time. This game was taken from the book, Secrets of Pawn Endings by endgame expert Karsten Muller.
White to play and win.
Answers are between the brackets.
[White wins by the technique I discussed not too long ago. It's called triangulation.
The same thing occurs here. White must pass the move to Black and put it into fatal zugzwang. Black can only move on the White squares so White simply triangulates.
1. Kg4 (1. Kf6 - stalemate) Kf7
2. Kh5 Kg8
3. Kg5 Kf7
4. g8Q+ Kxg8
5. Kf6! +-
Now the White King simply grabs all the pawns on e6, d5 and White wins easily.
