White to move. Is this a win or draw?

I think it should be a draw. Black can keep checking from the side.
white wins easily. kg6 stops checks, re6 forces re8 and rd6 and rd8 wins.

start with rf7.

White should win with 1. e7:
Several lines, but here are 3 examples:
1. … Kg7
2. Ra6 Rh8
3. Ke6 Rh6+
4. Kd7 Rxa6
5. e8(Q) etc.
Or:
1. … Ra5+
2. Ke6 Ra6+
3. Kf5 Ra5+
4. Kg6 Ra8
5. Rd6 etc.
Or:
1. … Re8
2. Ke6 Kg7
3. Rf7+ Kg8
4. Kf6 Ra8
5. Rg7+ Kh8
6. Kf7 etc.
This is a win for white after 1.e7
The most important factor here is that the black K is cut off from the pawn, and the black R alone cannot hold off all the white pieces.
If for example 1. … Kg7 2. Ra6! Rb8 3.Ke6
i think 1.e7 is winning. If black checks the white king from the side, he can hide on g6 (Ke6-f5-g6).
1. e7 Ra5+
2.Ke6 Ra6+
3.Kf5 Ra5+
4.Kg6 Ra8
5.Re6 Re8
6.Kf6 Kh8
7.Kf7 +-
or
1. e7 Re8
2.Ke6 Ra8 (2…Kg7 3.Rf1 Ra8 4.Rg1+)
3.Rg6+ Kh7
4.Rg1 and Kf7 +-

Yea, I missed that one. Black to move draws though.
