When the rook is as powerful as the queen!
" Fortresses in endgame always appeals to the spectator when a side with a material disadvantage holds his own in a seemingly lost battle. Like the attractiveness of sacrifice in chess, fortresses too capture the imagination of players and annotators alike," writes GM Sundararajan Kidambi. He saw the game between Lupulescu and Navara live from the European Club Cup 2017 and was drawn towards the beauty of the Czech grandmaster's tenacious play. In this article we discuss the fortress of rook versus queen, which is not only possible with one pawn per side, but also when the side with the queen is a pawn up! | Kidambi's image in thumbnail: Alina l'Ami.
Fortress in the Endgame by Sundarajan Kidambi
" In order to improve your game, you must study endgame before anything else" - Capablanca
The importance of studying the endgame in chess can never be overstated. As the Cuban World Champion has said, it is very important for every student of the game. I would like to deal with a couple of examples on the topic of fortresses in endgames. It always appeals to the spectator when a side with a material disadvantage holds his own in a seemingly lost battle. Like the attractiveness of sacrifice in chess, this too captures the imagination of players and annotators alike.
While watching the game Lupulescu-Navara from the European Club Cup a few days ago, I came across a wonderful example of a fortress. Immediately I was reminded of two examples from Averbakh's Best Games which I will share here. First here is a study by the great Composer Kasparian.
The solution to this study is very pretty. But (Un)fortunately there is a cook which was also found by Kasparian as mentioned by Averbakh which prevented the composition from winning a prize. Once you have tried to solve this study, take a look at the replayable board for the two solutions.
Averbakh vs Bondarevsky
Averbakh explains in his best games as to how knowledge of Kasparian's study helped him steer his game towards a fortress. Here are the notes to the key moments of the game by the oldest grandmaster alive.
Finally coming to the Lupulescu-Navara game from the European Club Cup. This is one critical moment from the game:
White to move has a unique way to win here. This was pointed out by International Master Sagar Shah. White missed it and the game resulted in a draw later. I analyzed the endgame and then discussed it with grandmaster Sandipan Chanda. We found some interesting ideas just before reaching this endgame. There are still some unanswered questions left as always! I present the product of our analysis here.
Some practical pointers derived from the analysis were:
1.The defensive side has to reach Kg7 Rook e6,g6 or h6.
2. Should not allow White's pawn to reach h6
3. Not allow White's Queen to f8.
4. If white has two h-pawns still the position is a draw if black reaches the safe squares e6 or h6 with King on g7 and h7. Black loses in that Qg3-h5 line because he is forced out of the safe square!
5. For the side, with the Queen, there are always tactical ideas even if it's just one tempo before the rook reaches the safe square, like in this example and also the Averbakh game.
My Thanks to Sandipan Chanda and Sagar Shah. Special thanks also to Averbakh and Kasparian for enriching chess literature through their works.
In Conclusion, I would like to mention that grandmaster Sandipan Chanda is one of the most creative minds of our country. Apart from being a fine player, he is also an avid composer. I give below his latest composition for the readers to solve and enjoy.
Ed: The solution to this position will soon be published. All we can say is that the solution slowly grows on you. Once you see the idea and think deeper about it you will realize what a brilliant composition this is.
