Puzzle #5 of puzzle contest

Welcome back, members of the puzzle contest! Sorry I was a bit late posting this puzzle. I'll still give you a week. Puzzle #4 answer:

Analysis: Material is even. Black's king is possibly vulnerable to the White rooks, and White's king is a little bit vulnerable to the Black rooks. The Black rooks aren't doing much and the only ones defending themselves is each other. The Black pawn isn't doing much either because a2 and a1 are both defended. The Black king is in the square of the White pawn. White's rooks can possibly help push the pawn and/or attack the Black king. The pawn is a little bit vulnerable to the king and possibly to the Black rooks. It turns out that White is better because his pieces are more actively placed.

White to move and win:

1 f7 Kg7 2 f8=Q+ Kxf8 3 Rf1+ Ke7 4 Rfe1 Rc3+ 5 Kb4 Rb3+ 6 Ka4 Rxe2 7 Rxe2+ Kd6 8 Kxb3 1-0 or 3...Kg7 4 Rg1+ Kh6 5 Rh1+ Rh3 6 Reh2 Rc3+ 7 Kb4 Rb3+ 8 Ka4 Rxh2 9 Rxh2+ Kg5 10 Kxb3 1-0 or 3...Rf3 4 Ref2 Rc3+ 5 Kb4 Rb3+ 6 Ka4 Rxf2 7 Rxf2+ Ke7 8 Kxb3 1-0 or 1...Rf3 2 f8=Q+ Rxf8 3 Kxb3 1-0

Also, I will have a new rule that if you do not answer for five puzzles in a row, you will be dropped out.

Now for the puzzle:

This one is particularly clever. Don't count me into the competition though.

Intially just queening the pawn would fall after Bxg6 Ka1 Be7, so the great move Nf4!! (threatening the h5 bishop)is needed. After gxf4, we can do the queening and when "Be7", Nf3! Ke7 Qxh4!!! Without Nf4, we could not have done this because the g pawn would still be there protecting it. Now after Bxh4, we have the fork with Nxg6+! winning for white.

This is hard...

edit: Nice solution Lord-Chaos. Sometimes I feel like I analyze every possible line except for the right one...

This is hard. Anyway, I don't want to join the compitition. So DO NOT count me.

i couldn't solve this :-(

First off white cant queen its always bad h8=q then bxg6+ ka1( forced ) be7 white has 2 options here they both suck a4 leads to bf6+ again 2options qxf6 (huge material loss for white )or ka2 bxh8 ( even worse) without moving the pawn or by moving the queen white is checkmated by bf6 checkmate  I think that black wins like this or something similar

1.Nf4 Kg7 2.Nxh5+ Kxh7 3.Nf6+ Kg6 4.Ne4 Kf5 5.Nc3 Bd6 6.h3 g4 7.hxg4+ Kxg4 8.Nce2 h3 9.f3+ Kh4 10.Nxh3 Kxh3 11.Kb2 e5 12.Kb3 Kg2

13.Nc3 Kxf3 14.Ka4 e4 15.Kxa5 e3 16.Nb5 Ke4 17.Nc3+ Kd3 18.Nb5 Bf4 19.a4 e2 20.Ka6 e1=Q 21.Kb7 Qe4+ 22.Kc8 Qe8+ 23.Kb7 Qd7 24.a5

c6+ 25.Kb6 Be3+ 26.Ka6 Qc8# 0-1

Black is one pawn up, however, white has the threat of queening. The immediate 1.h8Q falls to 1...Bxg6+ 2.Ka1 Be7 where the queen must fall due to Bf6#. The only move here would be 1.Nf4, which wins the bishop.

1.Nf4 1...Kg7 2.Nxh5

1...gxf4 2.h8Q Bg6+ 3.Ka1 Be7 4.Nf3! Bf6+ 5.Ne5+ Ke7 6.Qxh4! Bxh4 7.Nxg6, and later picking up the bishop on h4. 4.Nf3 does not work without 1...gxf4, as the g-pawn would still have been preventing 6.Qxh4, which is crucial to win.
