Nf3 looks ok. If h3 then Ng3+ Kg4 Ne2 and the promoting squares are both covered and should be able to be protected enough to allow white to promote his pawn.

White to move:
[fen]8/8/7p/3KNN1k/2p4p/8/3P2p1/8 w - - 0 1[/fen]
This problem comes from Mihai Suba, Dynamic Chess Strategy, and Fritz 8 misses white's best move.
1.) Nxh4 Kxh4
2.) Nf3+ (can fork and prevent the promotion if the pawn promotes. any If the Black king does not capture the knight, then the same fork can be had with Nf3 again and prevent the promotion of the pawn.
At this point, the White King can clear away the c-pawn, and prepare his own promotion strategy. Black's h-pawn is nothing to worry about, because white will promote before he ever gets there.
Then, King can work a way to the pawn, and capture it. And, then work on the other pawn that prevents his own promotional pawn. Not too difficult. Sac a knight.

Well, then
1....Ke4 2.g1=Q 3.Ng7ch Kg5 4.Nf3ch wins the queen.
If 1..Ke4 2.h3 Kf4!(threatens mate) 3.g1=Q Ng3ch, 4.Qxg3 Kxg3

White plays 1.Kc6! After 1...g1Q 2.Nxh4 Qa1 (or any queen move; 2...Kxh4 3.Nf3+ and if there is any advantage it belongs to white) 3.Nhf3, we reach the following position:
The black king is caged and the white pawn is protected. Black can chase the white king all over the board, but cannot deliver checkmate.

How Long did you Leave it for?? and/or How powerful is your PC??
I should imagine that Frtiz would have found the winning move simply by brute force evaluation....given a big Hash and time
