White to move. Is this a win, draw, or loss for White? How should White proceed?

I’m too lazy to give all the lines, but I think this should win for white:
g6 Be4
Nf8 Bxg6
Nxd7 Kb7
Nxc5+ K moves
Nxe6
Maybe there’s something better
g6 Be4
Nf8 wins
Brit-mate
1 g6 be4
2 nf8 bg6
3 nd7 kb7
4 nc5 K any
5 ne6.
White wins; the colored player loses. Is this really appropriate for MLK day?
1. g6 Be4 2. Nf8 Nf6 (2..Nf8 3. g7) 3. g7 and next move Nd7 wins for white Kb7 4. Nd7 Ng8 5. Nc5+ and takes bishop
White wins by offering a knight sacrifice by 1. Nf6! idea to create two threat 1. checkmate # at Nc5 and 2. promotion of pawn
Black can’t prevent both and white wins
1. g6 Be4
2. Nf8 Bxg6 (2. … Nxf8 3. g7)
3. Nxd7 Kb7 (else 4. Nxc5#)
4. Nxc5+ Kc7
5. Nxe6+ Kd6
6. Nf4 Be8 (with a potential discovered check protecting against 7. d4)
7. Kb4
This much seems pretty straightforward. White’s extra pawns should tell.
If 1. Nf6 then 1. … Ne5 allows Black to preserve the knight.
1.g6 Be4 2.Nf8! Ne5 (2..Nf6 3.Nxe6 Kb7 4.Nxc5+ Kc7 5.Nxe4 Nxe4 6.g7 Nf6 is won for white) 3.Nxe6 Nd3! (3…Nd7 4.g7 Bh7 5.Nf8 winning) 4.g7 Bh7 5.Nc7+ Kb7 6.Ne8 Bg8 7.Nf6 Bf7 8.g8=Q Bxg8 9.Nxg8 . That is best black can get from this position, It seems won for white, but there is a game.
1. Nf6 Nf8 guards both threats.
1. Nf6 Ne5 and White has no way to reach c5. After 2. g6 Ng6: is possible.
I’d propose
1. g6 Be4
2. Nf8 Nf6 (2. … Nf8: 3. g7 +-)
3. Ne6: Kb7 (to avoid mate on c5)
4. Nc5: +-
Or 3. … Nd7
4. g7 Bh7
5. Nf8 +-
it’s a very nice win after
1.g6! Be4 is the only move
2.Nf8!!
a) NxN 3.g7! classical theme +-
b)Nf6 3.Nxe6 Nd7 only move 4.g7 Bh7 5. Nf8 ! +-
g6 Be4
Nf8 Bxg6
Nxd7 Kb7
Nxc5 K..move
Nxe6 1-0
1. g6 Be4 (only move to prevent g7 and g8)
2. Nf8! …
if
A:
2 … Nxf8
3 g7 and the pawn is unstoppable
B:
2 … Bxg6
3. Nxd7 Kb7 (only move to prevent mate by Nxc5)
4. Nxc5+ Kc8
5. Nxe6 and white wins
C:
2 … Nf6
3. Nxe6 Nd7 (or else Nxc5 is lethal)
4. g7 Bh7
5. Nf8 and life becomes miserable for black.
Nf6 is the move. If
1. g6 Bf4
2. g7 BxN black wins, so the key is to control the bishop.
1. Nf6 NxN
2. gxN, the pawn queens on a black square and the bishop won’t have time to intercept.

It’s a win for white. Push the e5 pawn up the board and promote to queen. It can’t be stopped. Then go get the black king.
Yes, i do believe the white will surely win in this presentation. you can see the pawn at g5, black can’t stop until it goes to g8 and turn to queen.
I just visualized comment from Bruno above.
