Well done, Alena. That last section is extremely difficult to get through because of the several "only winning moves" white has to find, in particular 7.Ke4 and the need to manuever to keep the black king off the d-file so that the rook can't safely skewer the king and new queen from in between them.

No. 1-10

7.Ke4 Rd4

8.Kf3 Kc4

9.e6 Rd5

10.e7 Rxf5+

11.Ke4 Rxf2

12.Ke3 Rh2

A more testing defense for black is 6......Rd7+, and is the main line of the puzzle- it forces white to play more accurately.

V-4

1.Kb6 Rxd7

2.Kc6 Ra7

3.gxh7 Rxh7

4.fxe4 Kb2

5.e5 Kc3

10.Kb5 Rd6

11.Kc5 Rd4

12.e7 Re4

13.f6 Kc3

14.f7 Rxe7

15.f8=Q

It's a winning position for white.

This is very good, Alena. Now consider V-1 immediately above. There are two things you need to do now- first lets take you actual line 1.Kb6 Rxd7

2.Kc6 Ra7

3.gxh7 Rxh7

4.fxe4 Rh2

5.f4 Here, you had black putting the rook behind the f-pawns at f2 on move 5, now consider what white must do if black puts the rook on h4 instead to attack the backward f-pawn that way. Also, can you see why it had to be 5.f4? In short, 5.f4 forces black to capture at f4 thus gaining a critical tempo because it comes under attack. Finally, you need to tie up one very major loose end in this line, and that is where black plays 4......Kb2!- a much more tenacious defense than 4.....Rh2 is. That line after 4.....Kb2 is the heart and beauty of this puzzle.

When white brings the king to the b-file, black has time for three different moves- you found Rxd7 and hxg7, but there is third move black has the time to play- e3, and it is the critical one white has to find a way to defeat as a defense.

Editor

Alena, 1.Kb7 is wrong. You overlook a much better move for black at move 1. However, in a more general sense think about the position and how it might evolve. In one sense, I could eliminate 1.Kb7 almost immediately because of the capture at d7 occurring with check, though I also struggled a long time with black's first move even though I had thought of the right one pretty early on. So, black is going to have to find a way to draw this only the rook and king against connect passed pawns at some point, so the question is how does white find the time necessary to prevent the black king getting into the action for the typical double attacks on the backward pawns that allows a defense in such endings at times?
