1. Re7+ forces 1…Kh8 (1…Kg6 2. f5+ Kg5 3. Rg7+, or 1…Kf8 2. Ra7 Rh4 3. h8Q+ R:h8 4. Ra8+). Now 2. Rf7 Rh4 3. Ke3 R:g4 4. Ke4 will win the f-pawn.
It is not easy to get the conclusion if the position is won.
1.Re7+ Kh8 (Kg6 looses after f5+,Rg7+,g5)
2.Ke2 Rg3 (Rxh7 3.Rxh7+ Kxh7 4.f5 with Kd3-c4 wins)
3.g5 Rg4! (fxg5 4.f5 looks winning)
4.Kf3 Rg1
Now if white plays 5.gxf6? Rf1+ Ke4 Rxf4+! – draw.
So white has to play 5.Re8+ Kxh7 6.gxf6
May be it is won, but need to analyze it more and I have to go…
I think this is a draw.
Re7+ looks winning, followed by Ke2. If Black takes the h pawn, then White trades Rs, gets the opposition, and wins the Black pawn on f6. And if instead Black goes after the g pawn with the R, then White pushes g5, fxg5, and pushes past with the pawn to f5. With a more active K and the fast f pawn, White looks good to win this way too.
