The only winning move in this position for white, I am dead certain. Continuing:
6. …..g4 7. Rg8 h3 8. Kf1! Kf3
Or 8. …h2 9.Rh8 wins. Continuing:
9. Kg1 g3 10.Rf8 Ke3 11.Rh8 h2 12.Kg2 and the pawns will both fall to double attacks.
What was important in the line above was the white king making to g1 in time. This means there is no time to waste at the start, for black. He must play Kf4 immediately:
1. …..Kf4! 2. Rf7
No move for white here should win, now, and I can imagine some that might well lose. Continuing:
2. …..Kg3!
Probably the only move again. Now the h-pawn should secure the draw for black. Continuing:
3. Kd4
If Rg8, black can either push h3, or take at f3- either should draw easily. The point of Kd4 is to give black rope to hang himself:
3. …..h3 (an only move) 4. Rh7 h2 5. Ke4
Here, Rh2 is a draw, too. Continuing:
5. …..Kg2 (an only move) 6. Kf5
One last trap. Continuing:
6. …..Kf3!
It is easy to get careless here and play h1Q, but if black does so, Rxh1 followed by Kxg4 gives a won K+P ending. The rest is pretty clear cut:
7. Rh2 g4 (only move) 8. Rh1 g3 (only move)
And there is no way for white to double attack the pawn before it reaches g2. White will be forced to give up the rook for it.
The Black king MUST swing over to support the advance of the h-pawn right away.
1. … Kf4 2. Rxf7+ Kg3 3. Rg7
(3. Kd5 h3 4. Rf5 h2 5. Rxg5+ Kxf3 6. Rh5 Kg2 7. Rg5+ Kf3 8. Rh5 Kg2)
3. .. h3 4. Rxg5+
(4. Rh7 h2 5. Kd4 Kg2 6. Ke4 h1=Q 7. Rxh1 Kxh1 8. Kf5 Kg2 9. Kxg5 Kxf3)
4. .. Kxf3 5. Rh5 Kg2
I think the attempt to win this would probably cause most players to play f5 without noticing that time is of the essence in this position.
1. …..f5
2. Kc4! Kf4
3. Kd3! Kf3
4. Rf5 Kg4
5. Rf8 Kg3
6. Ke2
The only winning move in this position for white, I am dead certain. Continuing:
6. …..g4
7. Rg8 h3
8. Kf1! Kf3
Or 8. …h2 9.Rh8 wins. Continuing:
9. Kg1 g3
10.Rf8 Ke3
11.Rh8 h2
12.Kg2 and the pawns will both fall to double attacks.

at a very quick glance, surely it must be Kf4 and Kg3
Real question is, which Pawn does Black promote to win White’s Rook?
I tried hard starting with f5 but could not get the draw
