Yesterday we had the endgame masterclass in the game between Levon Aronian and Daniil Dubov, where both players had g-pawns and Aronian had a rook versus Dubov's bishop. Today, in the tiebreaks, the very crucial encounter between MVL and Grischuk saw the same material balance, just that instead of both sides have g-pawns, it was h-pawn and rook vs g-pawn and the bishop. The position is very instructive and something that we can all learn from. MVL setup a very nice fortress (hence, the title of this article!). But first let us understand the background.

The first two classical games of the match between MVL and Grischuk had ended in draws. The two 25' + 10" rapid games ended in draws as well, although it must be mentioned that in the first game Grischuk was clearly better with an extra pawn. As both the 25'+10" rapid games ended in draws, the action shifted to 10'+10" rapids. MVL was able to get in the first win of the match with the white pieces. All he had to do in the second game was to get the half point to qualify for the quarter finals. But MVL, being MVL, played the game in the most ambitious fashion. Grischuk won an exchange and extinguished his opponent's initiative. Finally we reached the following endgame:
In the above position if White plays h3, he is winning. The win is easy to demonstrate but requires some finesse. White first gets his rook to a6 cutting the black king. When the bishop moves from f4, the rook attacks the bishop (say Be3 Ra3 Bf4 Rf3!) Once the rook has an eye on the bishop, the king comes up via h6-h5 to g4 and then the bishop starts feeling uncomfortable. It's diagonal c1-f4 is too short because the rook attacks it and the h4 move prevents it from sitting comfortably on f4.
Grischuk did not play h3 and instead allowed Black to play g4 followed by g3. This was a substantial improvement for Black and after the game MVL thought that the following position was a fortess:
How should white win? A lot of schematic thinking is required here to win. Let's try to break down into steps:
1. Firstly White should get his king to f3 and rook to the g-file say Rg4. Now Black will have to keep his king on the h-file because if it goes to the f-file, then the h-pawn simply runs down the board.
2. Once the king is on the h-file, the rook must push the black king back to h7. This is possible because the white king can move to f5 and start threatening mates with the rook. Once the king goes to h7, the white rook must jump into g6 and cut the king off.
3. Now it is very important to get this position with black to play. If it is White's move he can move his rook to g4-g5- later g8 and get this position with black to play. Once you get the above position with black to play, it is zugzwang. I can see you asking zugzwang for what? Well, the reason is that white king must get to h5. If White is able to do that then he wins easily, as he gets his rook to g4-e4 and finally checking the black king from e7 and then penetrating to the g6 square with the king. So getting the king to h5 is very important. In the above diagram, black to move can either play Kh8 or Be1. Kh8 is met with Rg4 and Kh7 loses to Kg5 with Kh5 coming up. And if instead of Kh8, Black plays Be1, straightaway Kg5 is possible as g2 loses the pawn to Kh5. This means that you are able to get your king to h5. What next?
4. The black king can either go to h8 or the bishop goes to e1. Be1 is refuted with Re6! Bf2 Re7+ Kg8 Kg6 threatening a mate! So instead of Be1, Kh8 is possible, but White now chooses to push his pawn with h4 and Kh7 is met with Rg4. Black king going to last rank will lose to Kg6. And Be1 is met with Re4! Bf2 Re7+ Kg8 Kg6.
5. To...Kf8 in the above position, you must find the only move to win, Re2! Not so difficult. Now the king cannot move, the bishop has to and then White advances his h-pawn.
There are so many subtleties and so many little moves that White has to make in order to win the game. One of the very important things that White must be careful about is not pushing his h-pawn. On h3 it is safe. And it helps to keep the pawn away from the radar of black's bishop.
In the game Grischuk couldn't understand that his pawn must remain on h3. He pushed his pawn to h4 and now it is a draw. The key line being ...Be1 Kg5 g2! Kh5 Bxh4. And there you see the downside of pushing the pawn to h4.
Some more instruction on this endgame by GM Effstratios Grivas will soon follow. ChessBase wants to ensure that you become an expert in rook vs bishop endgames!

We have the entire game on the ChessBase India Youtube channel in video. The game was 10'+10" but lasted nearly 45 minutes. The videos are split into five parts. Here is the first one:

If there is one reason why we will see less chess fans at the playing venue from tomorrow, it is because Baadur Jobava was eliminated. Jobava is a big icon in the country and I realized this today when there was complete silence in the press room as he lost his match to Wesley So. Baadur with his solid play throughout the tournament had given Georgians a lot of hope. After all beating Yu Yangyi and Ian Nepomniachtchi was never easy. But Wesley So, proved to be a much harder nut to crack.
Every Georgian was cheering for their local hero Baadur Jobava! We show you the atmosphere in the press room while the game was in progress.

In the second game Wesley played the Petroff and was able to draw to qualify to the next round. Towards the end there was some drama related to three-fold repetition which we were able capture in a video:

This was a battle of styles. While Rapport likes to play unconventional chess and goes for super complicated stuff, Najer has a much more controlled style of play. He likes to play logical chess and his moves usually follow a plan or a scheme that he has formulated. The match was hard fought with each and every game going down to the wire. After three draws (two classical games and one rapid), the deadlock was finally broken in the second rapid 25'+10" rapid game.
If you too would like to play this line with 1.Nf3 d5 2.c4 d4 3.b4!? then you must definitely have a look at Bologan's latest DVD on the Reti where he talks about this line. In general he presents a repertoire for White beginning with 1.Nf3.
Starting with 1.Nf3 the Reti is designed for those players who like strategy, manoeuvres and plans. Bologan presents a repertoire based on 1.Nf3 giving you options for all major replies.

Peter Svidler explained that beating Magnus Carlsen one game in a row doesn't make Bu Xiangzhi "a mythical beast which you need to be extremely afraid and totally alter your strategy," adding, "he remains an incredibly strong player, that I have the utmost respect for, but that was what I thought before." Svidler was able to beat Bu Xiangzhi 2-0 in the rapid and advance to the quarterfinals. Svidler beating his opponent with the black pieces was the most crucial result of the match. Bu was under too much pressure to win the second rapid game with black and collapsed.

Although he is out, Bu will cherish this tournament for eliminating Magnus Carlsen. Who knows he might be the reason for a reigning World Champion never again to take part in the World Cup!
After staging a heroic comeback in the second classical game, Rodshtein was unable to maintain his momentum and lost both the rapid games to Vladimir Fedoseev. "I was not able to think properly," said Rodshtein after the game. Rodshtein goes back home, but takes with him a lot of memories. The positive feeling of beating Michael Adams, and the not so positive one of getting a walkover against Kovalyov.
