Sinquefield Cup 2017 Round 4: A knight fork spells Carlsen's doom against MVL

by Saravanan Venkatachalam - 06/08/2017

After gaining from the humble tactic of the knight fork in the 3rd round, it was the turn of Mighty Magnus himself to fall to the ruse, when he overlooked a simple detail and lost to Maxime Vachier-Lagrave in the 4th round, allowing the Frenchman to gain the sole lead with 3 points. The game also reinforced for the umpteenth time the all too often repeated and glorified cliche Chess is 99% tactics. Magnus' defeat and Nakamura falling to Nepo were the only decisive games of the round. The other three ended in draws. We have a comprehensive round four report from Saint Louis.

When Tony Miles passed away prematurely in 2001, Mathew Sadler, his teammate from the Elista Olympiad recollected how the legendary grafter unexpectedly played 6.dxc3 (instead of the established 6.bxc3) in an English Opening game and then went on to slowly outplay a Lithuanian International Master in a queenless grind of a game, much to the amusement of his colleagues. Carlsen chose exactly the same path in the same position on Saturday, but only, he chose one of the top 5 in the world for the treatment, and MVL may soon be reaching 2800 thanks to this victory and form in the tournament.

The unambitious 6.dxc3

By move 17, with black’s pieces looking more harmoniously placed towards the centre against his own uncoordinated army, it didn’t look like Carlsen was really the grafter of the day.

 

Carlsen - Vachier-Lagrave, position after 17...Ne5

Except for the bind on the queenside, there seemed almost nothing for white to be happy in this position. But mercifully for Carlsen, in the words of Anatoly Karpov, it seemed to be one of those typical minus positions where white could improve his pieces whereas it was difficult for black to chalk out a path of play, when you are not sitting with an engine next to you.

 

And Carlsen continued nonchalantly, concentrating on improving his pieces purposedly, stopping black from achieving anything meaningful.

Carlsen - Vachier-Lagrave, position after 33...Rg8

Now, it is dynamic parity, but this is where Carlsen starts with his ‘little’ games. 34.Ka4 (Just checking!) Rgd8 35.Kb3 (Fine thank you!) …

 

It is in such probing and rearranging that the World Champion excels, constantly unsettling his opponents, not allowing them to let their guard down even for a moment. Ultimately, after the time control was reached, he managed to extract an edge and once again looked to be taking over the initiative. Getting desperate, Vachier-Lagrave went for his chances:

Carlsen - Vachier-Lagrave, position after 45.Bg5

Understanding that he was not doing well tactically, MVL went for 45...Bxg3?! (The forced 45...Bf6 will run into 46.Bc6 when Black will have scrap for compensation for the exchange). And now, disaster struck: 46. Rg2?? A rare tactical blunder by Carlsen. Later, MVL would explain the fundamentals of the flaw which happened in Carlsen's calculation. (Forced was 46. Rd2 Rb8 (46... Rg8 47. Nxb6 !! axb6 48.Bc4) 47. Ka3! and Nd3 is in trouble)

 

46... Bh3 47. Rxg3 Bxf1 48. Rf3?? Blunder number 2! But this was follow-up of the flawed calculation which started off with Rg2 earlier (48. Bxd8 Rxd8 49. Rf3 Be2 50. Rxf5+ would have

still led to equality)

 

48... Be2 and only now did Carlsen realised that he missed a simple tactic here, the reason for his misery: 49. Re3 f4 50. Rxe2 Nc1+ and this knight fork nets the rook, which Carlsen overlooked. The position was beyond repair and the Frenchman triumphed.

Needless to say, the victory has been noted by all and sundry:

But the day’s drama had already begun elsewhere and the perpetrator was Nepomniachtchi, who showed no signs of the impulsiveness which made him lose the first two games. Pursuing a slight advantage from an Orthodox Queens Gambit Declined, Nepo exploited Nakamura’s inconsistent play very energetically and playing fast, taking just 33 minutes for the whole game.

Naka made life difficult for himself with 20...b6? (20...h6 or 20...g6 would have maintained parity)

 

21.Rcc1 g6 22.Ba6! And black is in trouble. The variation which Nakamura could NOT go in was quite pretty: 22...Ra8 23.Rxc6 Rxa6 24.Bd6 Qb7 25.Bf8 Qc6 and now the pretty fork 26.b5 wins the game for white!

To his credit, Nepomniachtchi played flawless and fast to win the game in just over two hours of play.

Elsewhere, Levon Aronian overcame his sluggishness of the last two days to once again start playing his favourite piece of wood on the board: the h-pawn!

Aronian remained consistent with the first round, and played 7.h4!? Bg7 8.h5 Bf5 9.Ng5 e6 10.h6!? and seemed to be working for a creative concept once again.

But to his credit, the former world champion remained calm and went back to his trusted ways and means...giving up the bishop for the knight.

But this was a game in which Anand probably didn’t exploit his chances, which might have been created by his opponent’s reckless push of the h-pawn in the opening:

Here, Anand could have pursued a push with 22...Nb3 23.axb4 (23.Rcd1 Nc2 24. Rf1 c4 is good for black) 23... Nxd2 24. bxc5 Bxc5 25. Rc2 Nb3 26. Ne4 Be7 27. Rc3 Nc5 28. Nxc5 Bxc5 and black still keeps an edge - remember the pawn on h6?! But the game ended after five more moves after a three-fold repetition

Peter Svidler - Wesley So was the bane of the spectator’s curse, the chaotic looking attacking game petering out to a simple draw due to the professionals’ deep opening preparation.

Even though the position looks threatening for Black, So came up with the coldblooded 25...Qg8 to maintain simple equality

Caruana - Karjakin was another of those perfect games where even though black sacficed a pawn, the game never got out of control, ending in a draw in 31 moves.
