FIDE World Cup 2017: Why didn't So sacrifice an exchange?

by Sagar Shah
9/20/2017 – Wesley So showed some excellent technique in the queenless middlegame to completely outplay his Chinese opponent Ding Liren. On the 40th move Ding made a mistake which gave Wesley an opportunity to sacrifice the exchange and torture his opponent for the rest of the game. Wesley had seen the move, yet did not play it. We try to find the reason why the American GM missed this opportunity. Aronian could not show anything concrete against MVL's Grunfeld and the players quickly agreed to a draw.

The positional exchange sacrifice is one of the most powerful and fascinating strategic weapons in chess. On this DVD Sergey Tiviakov explains why the positional exchange sacrifice is such a strong weapon and how to use it.

Two draws at the Semi-finals

The Hualing hotel is unusually empty. Only four players are left at the event. The number of journalists and media is also not very high. Six days ago, a playing hall that had 16 players, is now now down to just two tables. Although the number of people has diminished, the intensity and importance of every move has increased manifold. At the end of two days of classical chess and one day of tiebreaks (if required) we will have two players qualified for the Candidates 2018. Who will the be? According to the polls we had in our previous article, there is little distance between MVL and Aronian. But in the case of Wesley So and Ding Liren, our readers definitely think that the former is a big favourite.

The guard outside the playing hall doesn't recognize Wesley So!

If people thought So was a favourite, they were right, at least from the way the first game progressed. It was a Guioco Piano where things were around equal after the first 15 moves. Wesley then found an interesting idea:

 
In this position White went for the move Qb3-b5!

Black should have let the queen be. But instead Ding exchanged the queens and allowed White some clear plans to improve his position.

 
Wesley's idea of Ne3 and putting the pawn on c4 was very strong.

White's next plan was to get the rook from e1 to a1 and then shift his f3 knight from e1 to c2 and prepare the b4 break. Not feeling good about these moves, Ding went for ...a4. Now Ra1 can always be met with ...Nb3, but the a4 pawn surely becomes weak.

 
With just one and a half minute on his clock, Wesley went for the move 38.g5!

This was a very strong move, but also a very interesting decision. Usually when you make such important decisions you would like to have time on your clock. But So didn't make any waiting moves to reach the 40th move mark. He just played the best move in the position and was confident about his chances.

 
The critical mistake of the game took place when Ding Liren on the 40th move played Nc5-b3+.

The error couldn't have come at a worse time for Ding. 40 moves had just been completed and So had 30 minutes on his clock. Of course, Wesley had seen the best move in the position, but did not execute it. He played Kc3 and Liren found all the accurate moves needed to ensure a draw. The question is, could White have sacrificed an exchange on b3 and played for a win? I ask this question in the video below:

Million dollar question: Was Wesley So winning or not?

Update: The million dollar question has been solved! The win has been found for White. But not with the move 43.Kc3, but 43.Rg8! Check the analysis below our interview with Ding.

This was surely the best move in the position. Whether it was winning or not is unclear, but it surely gives White the best practical chances. 41.Rxb3! 41.Kc3? 3:10 Wesley let's his opponent off the hook.

He did equalize out of the opening, but after that he was clearly worse. And So played really well to only go back with the half point. 41...axb3 42.gxf6 gxf6 43.Rg8+! This is an update! White is winning after this move. 43.Rg7!? Rh2+ 44.Kc3 Ra2 45.Rxc7+ Kd8!

But I think it can also end at this point, saying that Wesley should have gone for this variation irrespective of whether he is winning or not because he has the best chances to press here. According to the official commentator Mirochnichenko, White can put his rook on g6 and then try for something like b4-c5. Although I am not really sure as both rooks can penetrate after b4 and start perpetual checks. What do you think? 43...Kd7 43...Kb7 44.Rg7 Rh2+ 45.Kc3 Ra2 46.Rxc7+ Kb8 The most important part being that the king is stuck on the wrong side. 47.Rc6 Raxb2 48.Rxb6+ Kc8 49.Rxd6!

So,W2810Ding,L2777½–½2017C50FIDE World Cup 20176.1

When I went for dinner I let my engine run, and when I came back I was confident about the evaluation of most of the variations as you can see from the depth of the engine.

 
The most critical position of the game.

It is pretty easy to look at active moves like Rg7 for White here, or Nxf6. But what is not simple to see is 41.Kc3! The idea: don't let Black establish both his rooks on the seventh rank. However, during the game prophylactic moves often go unnoticed. Later when I told this move to Ding, he was unaware about it and was very surprised that it existed. But within a fraction of a second he realized its strength. Wesley in his interview with press officer Anastasiya Karlovich said that he had seen the move Kc3, but thought it was not so easy to win. Perhaps objectively 41.Kc3 might not be 100% winning, but it gives White a risk free position and a chance to play for only two results. An opportunity that was surely missed by So.

Ding Liren speaks to us after the game

I have tried to analyze the critical moments of the game in quite some depth and I now share my analysis with you:

Update, September 20th: ChessBase readers  especially Mark S helped in finding the truth of the position and 43.Rg8! instead of 43.Kc3 - a prophylactic move which I thought was very strong. Here's the updated analysis.

1.e4 0 e5 12 Black goes for the solid 1...e5 in response to e4. In such important encounters, it makes sense not to go for Najdorfs and Caro-Kanns! 2.Nf3 0 Nc6 4 3.Bc4 0 Wesley plays the Giuoco Piano. After the game he said that he thought MVL was also white and there would be two Giuoco Pianos on the board! Nf6 22 Ding is not afraid of the move Ng5!? Usually we see top players reaching the main lines of Giuoco Piano through the 3...Bc5 move order. 4.d3 14 Bc5 10 5.c3 56 d6 2:56 6.0-0 35 0-0 6 7.Re1 0 a5 47 The first person to play this move was Boris Spassky in 1989. Later Eljanov and l'Ami played it, in 2016. The idea is to make luft for the dark-squared bishop, but at the same time prevent queenside expanstion by white. This does weaken the b5 square though. 8.Nbd2 0 Wesley had a good seven minute think before making this move. Be6 3:36 9.Bb5 5:15 The square b5 was weakened, so White makes use of it. We are already in virgin territory. Qb8!? 1:08 What an interesting idea by Ding Liren, taking a leaf out of the book of Akiba Rubinstein, who made a similar manoeuvre against Janowski in Karlsbad 1907. The queen will come to a7 and put more pressure on the a7-f2 diagonal. 10.Nf1 17:51 Qa7 1:31 11.Be3 8:03 Exchanging the bishops is the most logical thing to do here. Bxe3 2:10 12.Nxe3 1:06 Ne7 12 Black is preparing c6 and if possible also d5. 13.a4 2:06 Ng6 7:09 13...c6 14.Bc4 d5 15.exd5 cxd5 16.Bb5 And there can be some pressure on the e5 pawn in the future. 14.Bc4 4:06 Bxc4 5:25 15.Nxc4 6 Such positions are deceptive. One might feel that they are equal and perhaps they are. But one lapse in concentration and things can start going wrong pretty quickly. Mainly I would say White has the better chances here if he can engineer the d4 break. Qa6 49 16.g3 4:33 Stopping a Nf4 jump. Rfe8 1:49 17.Qb3 55 Nf8 3:58 18.Qb5 5:50 The white queen is well placed. Taking it will move the pawn to b5 and help White to create some play down the a-file. But can you tolerate this queen on b5? Qxb5 8:59 After the game Ding said that he shouldn't have taken the queen and instead should have continued with Ne6 or b6. 19.axb5 4 b6 3 20.Ra3 1:55 Ne6 2:18 21.Ne3 44 Nc5 5:32 22.c4 11 This might seem like a move where White has agreed to a locked position, but it turns out that Wesley has something to play for here. Mainly to put his knight on c2 from e1 and then try for the b4 break. a4 0 Ding thought for nearly 20 minutes coming up with this move. Let's give the move to White to understand what he is trying for. 22...h6 23.Rea1 Now threatening b4 Rac8 24.Ne1 The knight will go to c2 and prepare b4. It won't be an earth shattering advantage, but White is better. 23.Rea1 8:02 Nb3 57 24.Rd1 1:45 Rec8 0 24...Nc5 25.Ne1 25.Nd2 1:05 Nxd2 14:50 25...Nc5 26.Rda1 26.Nc2 was what Ding thought was pretty strong. c6 This seems like an error, but if this is not played then White will just go from c2 to b4 and control the c6 square. 27.bxc6 Rxc6 28.b4± 26.Rxd2 1 Nd7 10 27.Rd1 7:05 After the game Ding said that he would have gone for d3-d4 over here. 27.d4 exd4 28.Rxd4 Nc5 29.Nd5 27...Nc5 12 The other knight has settled on c5, but White's knight on e3 has quite a lot of scope as well. He will jump to d5 and then to b4 and c6 or he can go to d1 and c3. In general White has more ideas. Also the a4 pawn can become weak at some point. 28.Nd5 2:57 Kf8 1:49 29.f4 2 Wesley starts turning the screws on the kingside as well. Ra5 3:00 30.Nb4 1:39 Raa8 1:07 31.Kf2 1:05 Ke8 37 32.Ke3 0 Bringing the king to defend d3 is a good idea. The rooks are now free to do something better. f6 2:19 33.f5 7:57 At this point I entered the tournament hall and saw that Wesley was looking extremely focused and confident. Ding on the other hand was a tad nervous. Kd7 0 34.g4 20 White's plan is simple — go for a kingside breakthrough with g5. Rh8 3:18 35.h4 1:40 h6 2:00 36.Nd5 7:19 Ra5 50 37.Rg1 0 Kc8 29 38.g5! 2:21 I was expecting White to make a lot of moves before going for this break. But Wesley makes this breakthrough on move 38, just two moves away from the time control and having just one and a half minutes on his clock. A bold decision for sure. hxg5 1:44 39.hxg5 7 Rh3+ 25 40.Kd2 0 Nb3+?! 2:15 A mistake on the 40th move. 40...Rh2+ 41.Kc3 Rh3 42.gxf6 Wesley has calculated very accurately. gxf6 42...Rxd3+ 43.Kc2+- 42...Nxe4+ 43.Kb4 Nxf6 44.Ne7+ Kb7 45.Rxg7± 43.Kc2 Rh2+ 44.Kb1 41.Kc3? 3:10 Wesley let's his opponent off the hook. This was surely the best move in the position. Whether it was winning or not is unclear, but it surely gives White the best practical chances. 41.Rxb3! axb3 42.gxf6 gxf6 43.Rg8+! This is an update! White is winning after this move. 43.Rg7!? Rh2+ 44.Kc3 Ra2 45.Rxc7+ Kd8! I let the engine run for more than an hour while I went for dinner in this position and I can confidently say that Kd8 draws. 45...Kb8 46.Rc6!

Ding Liren knows that he was very close to defeat. But now he has the white pieces and in the last two matches (against Wang Hao and Richard Rapport) he has been absolutely ruthless when he has had the first move. Wesley will have to tread carefully against his preparation.

Aronian vs MVL

Levon ties his shoe laces and gets ready for the marathon! | Photo: Amruta Mokal

I somehow have the feeling that MVL has good chances in the World Cup format against Levon Aronian. Two things work in MVL's favour: strong nerves and more energy. If there is one thing that Aronian has a clear edge over his opponent, it would be superior opening preparation. Levon usually has new ideas up his sleeve. But in the first game his opening preparation was pretty dismal. We will come to it.

Initial moments of game one from the semi-finals

Look at Aronian's clock! They have played 23 moves and he has seven minutes more than what they started off with!

Looking at the clock one might think that Aronian had prepared everything from the white side of the Grunfeld. As it turned out, there was hardly anything to worry for Black. In fact at some point it felt as if White simply had no chances. The two queenside pawns were just too strong and it wouldn't be inappropriate to call this highly unsuccessful home preparation by Aronian.

MVL had no difficulties in holding the balance and drew without any issues. After the game he said, "I had looked at this line earlier this morning. I just didn't understand what Levon was trying to achieve. I had this game against Nisipeanu where both of us played the same line, but with the inclusion of the move ...h6. So I am well versed with the theoretical updates in this line." 

MVL and Levon are good friends | Photo: Amruta Mokal

Levon has the unique style of making his move with one hand and writing with the other! How do you like his green coloured shirt! Photo: Amruta Mokal

If I had to choose someone between the two, it would be MVL. Not by a big margin, but I do think that this format somehow suits him better. But, and this is a big but, Levon with the white pieces is a very dangerous opening theoretician. He always has new ideas up his sleeve. MVL has to be careful. 1.d4 0 Nf6 4 2.c4 0 g6 0 3.Nc3 0 d5 3 Of course, when it is MVL you can expect the Grunfeld. 4.cxd5 0 Nxd5 3 5.e4 2 Nxc3 4 6.bxc3 4 Bg7 0 7.Nf3 5 c5 6 8.Rb1!? 5 Whenever this move is played, I have a feeling that the players will blitz out their moves and will agree to a draw somewhere around the 30th move mark! Well, if Levon is playing at such an important moment in the tournament, he surely has something prepared. 0-0 26 9.Be2 4 cxd4 8 10.cxd4 6 Qa5+ 5 11.Bd2 6 Qxa2 5 This pawn sacrifice which surely looks risky has been seen in nearly 1500 games before! 12.0-0 5 Bg4 56 13.Be3 17 Nc6 1:50 14.d5 0 Na5 19 Of course the players are still blitzing out their moves. 15.Bg5 8 b6 1:57 16.Bxe7 9 Rfe8 5 17.d6 5 Nc6 8 18.Bb5 19 Nxe7 6 19.h3 57 19.Bxe8 has been seen in 10 games before this. Rxe8 20.dxe7 Qa3 21.h3 Bxf3 22.Qxf3 Qxf3 is an additional option that Black doesn't get in the main game. 22...Qxe7 transposes to the main game. 19...Bxf3 47 20.Qxf3 5 The knight is unusually trapped! Qe6 12 21.Bxe8 5 Rxe8 8 22.dxe7 4 Qxe7 0 22...Rxe7 23.Rfe1 Bd4 24.Rbd1 Qe5 25.Rd3 a5 26.Qd1 Bc5 27.Re2 Re6 28.g3 Rd6 29.Kg2 Rxd3 30.Qxd3 a4 31.Rd2 a3 32.Qc4 Kg7 33.Rd7 Qf6 34.f4 Qb2+ 35.Kf3 Qf2+ 36.Kg4 h5+ 37.Kh4 g5+ 38.fxg5 Kg6 39.Qc3 f6 40.Rd5 a2 41.Rf5 Qf4+ 42.gxf4 Bf2+ 43.Qg3 Bxg3+ 44.Kxg3 a1Q 45.Rxf6+ Kg7 46.e5 b5 47.Kh4 b4 48.Kxh5 Qd1+ 49.Kh4 b3 50.e6 b2 51.Rf7+ Kg8 52.Rb7 b1Q 53.Rxb1 Qxb1 54.Kg4 Qe4 0-1 (54) Gelfand,B (2733)-Shirov,A (2699) Odessa 2007 23.Rfd1 19 Bf8 21 24.Rbc1 5:34 The first new move of the game. And a good moment to take stock of things. What do you think is happening. Well we could just take into consideration that both near to 2800 players are playing at lightning speed and they are very well prepared, so it should be a draw. But if we keep this aside, I think it is an interesting position to analyze. The move Bf8, clearly points that Black would like to put his pawn on a5 and bishop on c5. Once he gets that he shouldn't really be worse. White's only chances are attached to his rooks penetrating into Black's position. I would say that the position is balanced with Black really having nothing much to worry. 24.Rd4 Qe6 25.Qb3 Qxb3 26.Rxb3 Bc5 27.Ra4 a5 28.Kf1 Bb4 29.Rbxb4 axb4 30.Rxb4 Re6 31.Ke2 Kf8 32.Ke3 Rc6 33.f4 1/2-1/2 (33) Shulman,Y (2617)-Svidler,P (2739) Ningbo 2011 24...Qxe4 9:22 25.Qc3!? 2:38 A very interesting decision by Aronian. He realizes that exchanging the queen will in all probability lead to a draw, so he keeps the queen and his clock still shows 1:29:59, which means this is his preparation. But as many people said after the game, they absolutely did not understand what Aronian's preparation was all about. He just landed in a position where White has no real chances to win. 25.Qxe4 Rxe4 26.Rd7 a5 27.Rc6 27.Rcc7 Rf4! 28.g3 Rf6 29.Kg2 Bc5 27...a4 27...Bc5 28.Rf6 Re1+ 29.Kh2 a4 30.Rfxf7 a3 31.Rg7+ Kf8 32.Rxh7 Ke8∞ 28.Rxb6 a3= This shouldn't be anything for White, with the pawn so far advanced and defended by the bishop. 25...Qb4 13:57 25...Bc5! would have been a good idea. 26.Re1 Qc6 27.Rxe8+ Qxe8 26.Qa1 4:11 Bc5 5:13 26...a5 was possible, but MVL is trying to get some clarity in the position by creating threats. 27.Qxa7 1:22 Qb2 17 The f2 pawn is not attacked and Rf1 will be met with Re2. 28.Kh1! 1:07 A nice move by Levon. Now taking the f2 pawn will lead to a rook coming on f1 and attacking the f7 pawn. Bxf2 9:20 Maxime is not really afraid of the rook coming to f1. 29.Qb7 10 29.Rf1 was also possible and White has some pressure, but nothing special. 29...Qe2 4:31 30.Rf1 9 Rf8 19 31.Qc6 1:34 Bc5 32.Rce1 The f7 point is defended by the rook. The b6 point, by the bishop, so in short there is no real problem for Black. Levon realized this and offered a draw. ½–½

The most effective, timeproven way to develop tactical abilities, imagination, and the ability to calculate variations, is practice. The 69 exercises on this DVD are taken from grandmaster games and show tactical ideas that are typical for the Grünfeld.

MVL's coach at the event Etienne Bacrot said that Maxime could have made his opponent's life tougher with some accurate play, but the evaluation (0.00) would not have changed much | Photo: Amruta Mokal

Maxime Vachier-Lagrave speaks about his game with Levon Aronian: "I just didn't understand what was going on!"

Expectations and Statistics

(click to enlarge)

38 games: 10 wins for MVL, 7 wins for Aronian and 21 draws (including one today)

In the past whenver Maxime has opened his game with 1.e4, Levon has replied with 1...e5. The players have played eight games in the Ruy Lopez. In their last encounter MVL went for 3...Bc4. This led to a win for the French grandmaster in the London Chess Classic. The chances of us seeing Giuoco Piano tomorrow is pretty high. I have a feeling that Aronian wil be able to hold it with the black pieces tomorrow against MVL. If the match does go into the tiebreaks the younger of the two — Maxime Vachier Lagrave will surely have an edge.

17 games: 2 wins for Wesley So, 2 wins for Ding Liren with 13 draws (including round one here)

It's very interesting to note that the first game that So and Ding played with each other was way back in 2004 at the World under-12 Championships in Heraklion. Ding won that encounter. The next time they sat opposite each other was in the first round of FIDE World Cup 2011 in Khanty Mansiysk. Both of them had a rating of around 2650. So managed to clinch that match as he won the first game of the rapid tiebreaks. In 2015 Wesley scored another win over Liren at the Bilbao Masters. In 2016 the pair played four game match in Shanghai. Ding was able to win that match 2½-1½. 

The Chinese player likes to open his games with 1.d4 and there are high chances that we might see Catalan in action tomorrow. Who do you think will win?
