3. f7
Black rook can not go to f3 or c8 and white is going to queen f7 pawn next.
1. c7 Kc7: 2. Rc3: Rc3: 3.f7 +-
1.c7 Kc7: 2. Rc3: Rc3: 3.f7 +-
c7 and pawn on f-file cannot be stopped from queening
1. c7 Kc7
2. Rc3 Rc3
3. f7
1. c7 Kxc7 2. Rxc3+ Rxc3 3. f7 and white will queen and white shouldn’t have any difficulties winning from there.
Let us see…how about
1. c7 Kxc7
2. Rxc3+ Rxc3
3. f7 1-0

From Michael,
1. c7 Kxc7
2. Rxc3! Rxc3
3. f7 1-0
1. f7 Rf1
1. … Ke7 2. c7
1. … c2 2. f8=Q+ with check
2. Rxc3 Txf7
2. … Kc7 3. Rf3!
3. c7 Rxc7
Giving checks does not improve things for Black:
3. … Rh7+
4. Kg3 Rg7+
5. Kf4 Rf7+ (Rxg2 6.c8=Q!
6. Kg5 Rg7+
7. Kf6 Rxc7 forced now
4. Rxc7 Kxc7
5. Kg3 and White wins, e.g.
5. … Kd7
6. Kf4 Ke6
7. Kg5 Kf7
8. Kh6 Kg8
9. g4 Kh8
10. g5 Kg8
11. Kg6 Kf8
12. Kh7 and queens
1. c7 Kd7
(If 1…Kxc7 2. f7 Rf1 3. Rxc3+ Kd7 4. Rf3 and white wins).
2. c8=Q+! Kxc8
3. Rxc3+ Rxc3
4. f7 and black cannot stop the f-pawn.
I think…
1. c7!! Kxc7
2. Rxc3+!!! Rxc3
3. f7 1-0
1. c7!!…Kxc7
2. Rxc3+!!Rxc3
3. f7!! and the white pawn queens! It cannot be stopped as both King and rook cannot catch it!
Harry
Controlling f3 is important here, and leads to 2 nice sacks:
1. c7 Kxc7
2. Rxc3+ Rxc3
3. f7
Neither rook nor king can stop it, both are misplaced. Up with Q vs. R.
1 – 0
1. c7 Kxc7 2. Rxc3+ Rxc3 3. f7 1-0
Looks quite easy.
1.c7 Kxc7
2.Rxc3+ Rxc3
3.f7 The pawn can not be stopped from queening.
1 c7!! kxc7
2 Rxc3+ Rxc3
3 f7
c7
c4
1.c7 Kd7
(1. …Kxc7
2.Rxc3+ Rxc3
3.f7 wins, cause the g-pawn keeps f3 square and King is not closed enough to reach f pawn)
2.Rxc3 Rxc3
3.f7 and black cannot avoid f-pawn promotion.
Sorry, I missed up one move in the last comment.
1.c7 Kd7
2.c8=Q+ (I missed up this very important move)
2. … Kxc8
3.Rxc3+ Rxc3
4.f7
Now actually white wins
