Is the rook endgame really drawn?

by Sagar Shah - 10/08/2017

In the fourth round of the Chaleroi Open 2017, Sagar Shah played a rook endgame against WIM Andreea-Cristiana Navrotescu. In a rook endgame where she was two pawns down, Andreea resigned. Later when Sagar went back home and analyzed the position, he realized that the position was not so simple. He discussed the position with Tigran Gharamian, who couldn't find a win, and later with GM Sandipan Chanda. The position is still very rich and open for discussion. What do you think? Is it still a draw?

This position (given below) occurred in the fourth round of the Charleroi Open 2017 in Belgium. My opponent was the talented French WIM Andreea-Cristiana Navrotescu, who made her maiden WGM norm in the same tournament.

 

Andreea-Cristiana Navrotescu vs Sagar Shah

I took the pawn on f4 with my rook and my opponent resigned.

When my opponent stretched her hand in resignation, I did feel that it was slightly premature. However, I also had the belief that Black should win this position. Two pawns up in a very standard situation with no real threats should be good enough to win, right?

 

Well, I went back home and analyzed the position and to my great disbelief was unable to win the position. After the tournament ended I analyzed the endgame with my good friend and Levon Aronian's second Tigran Gharamian (2616). Tigran couldn't believe when I said that the position was drawn. He tried for next hour to break down White's defences but without any success. I present our analysis below.

my findings of this rook endgame. I would really be interested if someone has
something more to add to it and is able to find a win for Black. As far as I
could analyze and also work with Tigran Gharamian after the tournament, we
came to the conclusion that the game was drawn.} *

The tournament was over, Tigran had won the event, but a dedicated chess player never misses out on an opportunity to learn
After the tournament in Belgium I travelled to Warsaw for my next event in Suwalki, Poland. I was going to stay one night in Warsaw and catch the train to Suwalki on the next day. As I reached the capital of Poland I received a mail from GM Sandipan Chanda, "Hope you have reached Warsaw safely. If you are not too tired, let's meet and recheck your endgame!" Sandipan was also in the same city!
Now I had travelled for nearly ten hours from Brussels to Warsaw, and was quite tired. But it was a great opportunity to see some new ideas in the position with a great analytical expert and of course I didn't miss it.
Sandipan met us with a smile and a pocket chess set!
After walking through the historical city for a few minutes and catching up with each other's life, Sandipan and I sat in Pizza Hut ordered an unlimited salad each and started our analysis!
Sandipan had read my report on ChessBase.com and had analyzed the position for some time on his own without using an engine. He shared his findings with me. (And yes, the salad wasn't enough!)
Sandipan's main idea was to first take the black king back to h6, then get the rook from e4-e8-h8-h7-e7 and free the king. And then slowly improve the position and get the following setup:
Black can get this position for sure. And it seems as if he is winning, because he can go Rd4 or even Ke5, threatening f4+. If Black gets f4+ and Kf5, he is winning. Sandipan's idea was not at all easy to refute.

 

However, later the correct defence was found. White should keep his king on f4 and rook on a4. Rd3 followed by Rh3 looked like a strong idea. However, White is fine after Ra6+ Kg7 Ra7+ Kh6 and Ra4! The point is to meet Rh3 with Ke5-Kf6 with a draw!

 

We tried many ideas during our dinner at Pizza Hut, but Black's defences are holding on. I would like to invite you to this discussion to put forth your ideas. What do you think? Is this a win for Black? The thing that I find extremely weird is that if this position is a theoretical draw, why hasn't it been covered in any popular endgame manual. Is it really a draw? Or am I missing something? I look forward to hearing from you in the comments section below.

 

A huge thanks to my two great friends Tigran Gharamian and Sandipan Chanda for spending time on this endgame and enriching my understanding.
