# Rook And Pawn Ending Study

Another study by Nicolai Ryabinin. The first move isn't all that difficult to find, but finishing off the win takes some thought.

- d7!

a) 1...Rb8 (forced), 2. Ra1+! Kb6, 3. Rb1+ Ka7, 4. Rxb8 Kxb8, 5. d8=Q+ Kb7, 6. Qd4 and White wins

b) 1...Rh5+!, 2. Kg2! Rh8, 3. d8=Q Rxd8, 4. Rxd8 c3, 5. Rc8 Kb6, 6. Rf8! c2, 7. Rf1 Kb5, 8. Rc1 Kb4, 9. Rxc2 c5, 10. Kf3! c4, 11. Ke2 Kb3, 12. Kd2 and White wins!!!

Yes, I understand why Rf8 is the only move to win.

Illyrialady, according to my notes on this study, I pretty much settled on 1.d7 for no other reason than it was counterintuitive to 1.dxc7 which, as you note, only draws. For the me the hardest part of this puzzle was the second move and the sixth move. In some sense, I realized pretty quickly why 2.Kg2 was better than the alternatives- white must keep the king closer to c1 to stop the pawn once the rook has been won, but it took me a while to work out why 6.Rf8 was required in the second variation Alena gives above.

Editor

Alena, good. Now you can see why it had to be 6.Rf8, but not the similar looking 6.Re8, 6.Rg8, and Rh8, right?

Well, I was wrong.

According to Nalimov database, Black can draw but

only if after

- dxc7 Rc5
- Rd5 Rxd5
- c8Q Kb4!

Every other move there by Black loses.

- c8Q

- Rd5 Rxd5

- dxc7 Rc5

Yes, the line starting 1. d7 I looked at as well. Oddly enough, although it is much slower, I think that 1. xc7 wins as well:

OK, Yancey. I considered this line but I thought it wasn't the strongest line.

4.Rxd8 c3

5.Rc8 Kb6

6.Rf8 Kc5

7.Rf2 Kd4

8.Kf1 Kd3

9.Ke1 c2

10.Rf3+ Kd4

11.Kd2 c1=any piece

12.Kxc1

It's a winning position for white.

Editor

Alena, I want to focus on the line after white's fourth move; black puts up more resistance and deepens the study by playing 4. ....c3. How should white respond?

The first move is obvious but the second move isn't obviuos.

1d7 Rh5+

2.Kg2 Rh8

3.d8=Q Rxd8

4.Rxd8 Kb5

5.Rc8 Kc6

6.Rf8 c3

7.Rf2 Kc5

8.Kf1 Kd5

9.Ke1 Kc4

10.Kd1 Kd5

11.Kc2 Kd6

12.Rf3 Kc6

13.Rxc3+ Kb6

14.Kb3 Kb7

15.Kc4 Kc6

16.Kb4+ Kd6

17.Kb5 Ke5

18.Rxc7 Kd6

It's a winning position for white.

It seems to me that I got used to solving more difficult Yancey's puzzles.
