Levon Aronian vs Daniil Dubov

How difficult are chess endings? Let's have a look at the very interesting endgame reached by Levon Aronian against Daniil Dubov. This position was reached after 45 moves in Aronian-Dubov:

 

It's very easy to just brush off this problem by saying White will bring his king up the board, push black's king behind, win the g-pawn and go back home with the full point. And yes, when you start making the moves, I agree that the following position is easy to reach.

 

But now what? How should White win this game? Look closely at the position, the bishop will keep moving on the b1-h7 diagonal and White has to make progress. Rc7+ is met with Kg6 (guarding the f6) square. It's a nice position to think about and learn a few things about the endgame. Just so that you would not see the solution, I have given the analysis and explanation at the end of the article.

Levon Aronian advances to round five where he will meet Ivanchuk

A short chat with Levon Aronian after the game:

diagram

Sagar Shah (SS): Levon, these young Russian players are giving you a tough time. First Matlakov and now Dubov.

Levon Aronian (LA): Yes, it was never going to be easy at the World Cup. Both of them fought really hard but I am glad that I was able to beat them and advance to the fifth round.

SS: This idea with h6 and e6 after the opening looked really dangerous.

LA: Yes, it was a very dangerous idea for myself. I nearly landed in a losing position! If he would have played Rac8 instead of taking on d4 later I would have been in a lot of difficulties.

SS: Levon, everyone is curious to know about the cat t-shirt that you wore in your tiebreaks against Matlakov.

Why did Aronian wear the cat shirt?

LA: Well, you know I always come to World Cups with lot of clothes in the hope that if I keep advancing to the next rounds I will need a lot of them to wear. However, except for the one time that I won the World Cup, I had to always leave early making my clothes useless. So this time I decided that I would carry less clothes with me. As it turned out before the tiebreaks with Maxim, I had very few options available and I decided to wear this t-shirt. I am very much looking forward to my rest day tomorrow to go shopping and buy some new clothes."

SS: Ding Liren said that he was going to wash his clothes tomorrow on the rest day.

LA: Yes, I think I would also be doing something similar!

Vladimir Fedoseev vs Maxim Rodshtein

One thing that Vishy Anand and Magnus Carlsen had in common this past week was how they were eliminated: losing game one, with the white pieces, in their respective matches. Even though their opponents were rated more than a hundred points below them it was just impossible to create chances with the black pieces. However, Maxim Rodshtein was not only able to create chances with black, but also exploit them against higher rated opponent Vladimir Fedoseev.

"My main intention was to choose a fighting opening," says Maxim. "I was quite irritated by my play in the first game because I was doing quite well until a point where I clearly went wrong. My opponent played a little too safely in the opening. In general it makes sense to play for a win even when you need a draw in this tournament. Because playing for a draw often puts you in an awkward situation. I was not better out of the opening, but I got this interesting option of taking on e5 with the bishop and creating some imbalance. In the end my opponent could have defended the rook endgame better, but it's very difficult to do it practice."

 

The tiebreaks between Rodshtein and Fedoseev are surely going to be very interesting. 

Anish Giri vs Vassily Ivanchuk

Anish Giri had been having a topsy turvy tournament here. He saved many a losing positions. Today he once again landed in a bad position against Vassily Ivanchuk.

Giri's luck ran out

A very interesting moment in the match. Anish Giri offers a draw to Ivanchuk. If Chucky accepts it, he would progress to the next round. However, the Ukranian GM had a winning position and he decided to continue playing

Anish defended staunchly and managed to create huge technical problems for Ivanchuk. Finally Chucky decided force a draw and he was happy to find a perpetual check to Anish's king.

The final draw from Ivanchuk captured in this video

One of the best qualities of Giri is that he doesn't get too flustered by the result. He keeps his calm and analyzes with the opponent.

Ivanchuk speaks about his win in the match. At the end he is asked the question what chess means to him. Check out what he has to say?

Ding Liren vs Wang Hao

Wang Hao played a strong tournament to knock out Boris Gelfand in round two. He also played well in the third round against Martyn Kravtsiv. However, he was knocked out in the fourth round. Ding Liren beat Wang Hao and advanced to the fifth round. It is for the first time that Ding Liren has gone this far in the World Cup. Last year he was eliminated by Wei Yi in the fourth round.

One of the two remaining Chinese had to go out this round

Is this Ding's year?

 

Ding speaks about his win over Wang and also tell us his plans for the rest day: to wash some clothes!

Baadur Jobava vs Wesley So

You have the spectators area filled with people because their local star Baadur Jobava is playing top class chess

Baadur had Wesley So in great trouble, but in the end the American managed to hold

A pleasant surprise for Alexander Grischuk as he meets and chats with Viktorija Cmylite-Nielsen. Did you know Viktorija is the wife of Peter Heine Nielsen and works in the Parliament of Lithuania?

Alexander Grischuk made a quick draw against Maxime Vachier-Lagrave. The two will play in the tiebreaks now.

Everyone in the around the playing hall are hooked onto chess. Here you see the guards trying to follow the game of Baadur Jobava.

Solution to Aronian vs Dubov

 

If you look closely at the position you will see that you can always force the black king to g6 with a check. After that is done, the bishop on b1 is left with five squares: b1,c2,d3,e4,f5.

White has the king and rook which will try to take squares away from the bishop. However at any given point of time, the rook can take away two squares from the bishop and the king can also do the same. That leaves the bishop with one extra square. This work has to be delegated to the g-pawn.

Hence the ideal setup would be rook to b2, king to d4 and pawn to g4. All the squares on the b1-h7 diagonal are covered (as the black king is on g6) and the bishop has to move off the diagonal.

 

I think the important thing to know in this position is that you have to push your pawn to g4. If you don't do that you will not be able to win. In the actual game Aronian made a lot of mistakes and was not able to find the winning plan. He won the game when his opponent blundered. A very thematic and interesting position.

I always thought Ivanchuck was an ass but now I like him. Old age I suppose...

Look at the photographs - sloppy tee shirts and jeans seem to be the rule rather than the exception for the players.
Are the players voluntarily dressing that way by solidarity with Anton Kovalyov?
Kilovs 2016 Kilovs 2016 9/14/2017 05:56
Go Wesley!! Good Luck on your next game.
Bojan KG Bojan KG 9/14/2017 04:06
Many errors from both players but who could blame them - chess is extremely complex even with only 6 pieces on the board. Every credit to Dubov, he could be star in the making. On the other hand I must say Levon got away with win again and to go all the way he must improve his game. Chucky will be tough opponent - genius, experienced and eager to qualify for Candidates after so many years in the wilderness. Lev is slight favorite but I would not be surprised seeing great Vassily upset him.

is that cat shirt ok to that rude organizer or since he is aronian, he has no guts to say anything?

Agreeing with Resistance, just great and honest reports! Thanks!

@genem

That is not a bare "convention": the specific placement of the kings signals to the electronic chessboard both the end of the game and its result, so that the device is able to output it to its management program and the latter in its turn to the web. What you propose would require not only an additional "piece" in the electronic chess set, but also the ability from the chessboard to detect its orientation: clearly an unnecessary complication.

Thank you for your reports, Sagar. I wish every tournament had such enjoyable and didactic daily articles like these...

I don't like the common convention of the Arbiter erasing the final position by relocating the two kings to the center squares next to each other. Instead of disturbing the final position, the Arbiter could place a simple non-chess-piece object onto the board, to indicate Game over. Perhaps a single standard 6-sided dice could be set to 1=White won, 6=Black won, 3/4=Draw.

Aronian - Dubov

This endgame is extremely complex, but is "solved" by the 6 piece endgame tablebases.

From move 47. Rxb5 the position is a 6 piece endgame tablebase position.

From move 43...Rxe7 until move 73. g3? the position is always winning for White.

From 73. g3? until 92...Bd3?, there are 18(!!) moves played that change the evaluation either from winning to drawn, or from drawn to winning.

The final blunder was 92...Bd3? when 92...Ke5 is the only move that draws.

After 47. Rxb5, it might be worth pointing out that the most stubborn defense by Black, 47...Kg6, (with best play by White), takes 42 moves of maneuvering before a pawn push, capture or checkmate occur. If White deviates, it takes more than 42(!!) moves to reset the 50 move counter.

Why isn't Azmaiparashvili demanding that Aronian change out of his cat shirt?
