This is a more complex example. White cannot penetrate with his king to the queenside directly, so first he must make progress on the kingside. He should try to play g4 and exchange his g-pawn for Black's h-pawn; a position with White's king on g5 and an h-pawn against Black's g-pawn is winning (see the game).

1.g3?
[1.g4! wins. After 1...hxg4 (1...g6 2.Ke3 and Kf4, as in the game) 2.Kg3 Bf3 if Kxg4 ever happens, White wins as in the game 3.Kf4 Ke6 4.Bd4 g6 5.h3 Black is in zugzwang. A bishop move allows Kxg4, a king move to anywhere apart from d6 allows hxg4 followed by Ke5, ...Kd6 allows hxg4 followed by Kg5 and a8Q. Finally ...g5+ is met by Kg3 and the g5-pawn is fatally weak.]

1...Ke6 2.Ke3
[It's too late for 2.g4 , as after 2...hxg4 3.Kg3 Black can play 3...Kf5 ]

2...Bg2?
[After 2...Kf5! 3.Bf8 g6 4.Kd4 Bg2 5.Kc5 Ke6! 6.h3 Bh1 White can never arrange to take back with his king on g4, so it is a draw.]

3.Kf4 g6 4.g4 hxg4 5.Kxg4 Bh1 6.Kg5 Kf7
[Or 6...Be4 7.a8Q Bxa8 8.Kxg6 and White wins.]

7.Bd4 Bg2 8.h4 Bh1 9.b4 Bg2 10.b5 Bh1 11.Bf6 Bg2
[11...Be4 12.Kf4 followed by Ke5 wins for White.]

12.h5! gxh5 13.Kf5
[13.Kf5 After 13...Bh1 14.Bh4 Bg2 15.Ke5 White's king simply marches to c7.] 1-0
