Norway Chess: Carlsen's unfortunate bishop

by Marco Baldauf
6/4/2018 – Wesley So showed his usual modesty when he declared that he had "caught Magnus on a bad day", after defeating the World Champion for the first time in his career. Carlsen was not at his best today — his light-squared bishop looked particularly tragic, as it spent most of the game stranded on the b1-h7 diagonal. The remaining games ended in a draw. | Photo: Lennart Ootes

Caruana and Mamedyarov reach quick draws

Shak Mamedyarov had given away a White in Saturday's game against Hikaru Nakamura, as the American defended successfully from the Black side of a trendy line in the Nimzo-Indian. In fact, the draw was agreed in just over half an hour. Thus, the world's current No. 3 was well rested before today's game. Against Anand, he played a Spanish with 3...g6, a line he had used to win his first game at the Candidates. Anand's opening approach was not convincing, as it allowed Mamedyarov to equalize easily, and the game ended in a draw without any hassle.

Fabiano Caruana accomplished his task even faster than Mamedyarov. He was "Black against Aronian", a pairing that would never be described as a walk in the park. However, Caruana came from defeating the Armenian, not once but twice, in the Candidates tournament.

Caruana chose the Vienna Variation against Aronian, the same opening he had used in Berlin. It was a risky decision, as Aronian is considered one of the best connoisseurs of this sharp system. For Caruana, however, this was not reason enough to avoid it. Nonetheless, Aronian adopted a fundamentally different strategy than the one he had used in Berlin. Right out of the opening, he went for an endgame with a very small edge, avoiding any risks. In the Candidates, Aronian urgently needed a victory, so he exposed himself too much, and at the end had to leave empty-handed.

So 1-0 Carlsen

Wesley So stunned the chess world today. Magnus Carlsen was having a great tournament until the sixth round, leading by a full point, apparently headed to an undefeated tournament victory. On top of this, Wesley So had never defeated him in his career. The American often played too solidly, and was not able to throw the World Champion off balance. Today, however, the game took a very different turn. The final position itself is worth a diagram: had you ever seen Carlsen in such a bad position?

 
So-Carlsen: Position after 44.c6

A crumbling World Champion

So is only a pawn up, but that is enough to win, as it will queen after 45.c7 and 46.Rb8. Carlsen's a-pawn is too slow to counter this threat. The bishop on h5 is fenced by white pawns and, in the truest sense of the word, has become a marginal piece.

So

So was very happy about getting his first win against Carlsen. This seemed more important to him than the fact that the fight for first place in Norway is now completely open again. Carlsen still leads the standings, but So is only half a point behind — and Magnus has played one extra game! (Carlen will rest tomorrow, as he is paired against Ding Liren).

Carlsen played the Exchange Variation of the Slav, a provocative choice that avoided the main lines after 6...a6 and 10...Nd7. Nakamura's verdict was that Carlsen's play in the opening was to blame for his defeat.

 
So-Carlsen: Position after 13.a3

White's Nc5 is faster than Black's ...Nc4

So threatens to make further progress on the queenside with 14.b4, therefore, Carlsen activated his knight with 13...Na5. "White, however, is faster" (So), and after 14.Nc5 White already had a slight advantage. A rare circumstance against Carlsen, who in the past had always been able to neutralize So's somewhat tame white repertoire. Probably, this was the crux of the matter: Wesley's calm play proved to be too much of a provocation for Carlsen who, after a very strong performance in the tournament, arrived to the game highly confident.

The fate of the game started to take shape when Carlsen's bishop was driven back to g6 after 18.f3. This bishop — often an annoyance to Slav players — eventually degenerated into a tragic figure. Wesley soon managed to take it out of the game with e4, and it was cornered down even further with the advance of another White pawn to f5. The final position is the best proof that the game did not go well for the proud bishop.

 
So-Carlsen: Position after 18.f3

The bishop was destined to oblivion

Ten moves later, when 28.e4 was played, it was clear to everyone in Stavanger that the position of their hero was not going anywhere today.

 
So-Carlsen: Position after 28.e4

The bishop's position keeps deteriorating

The next shock did not take long to arrive. After 34.f5, Carlsen's fate was sealed. Vachier-Lagrave and Nakamura talked about this game during their post-mortem interview and stated clearly that the position was already lost for Carlsen. This was not what the Norwegians wanted to hear.

 
So-Carlsen: Position after 34.f5

Carlsen already lost

Nakamura and MVL were right. After 34.f5, the h-pawn started to plough ahead and, finally, So's g-pawn stormed to g6. It was over.

Nakamura treated the opening creatively but did not prevail at the end. A draw was agreed, and both seemed satisfied with it, even though they continue to be winless in Stavanger.

1.e4 c5 2.Nc3 d6 3.d4 cxd4 4.Qxd4 Nc6 5.Qd2 Although it is not official, the players called this strange looking structure the Carlsen Variation. That should be enough to use this name here too. g6 5...Nf6 6.b3 e6 Wojtaszek used this construction and was gradually outplayed. 7.Bb2 a6 8.0-0-0 b5 9.f3 h5 10.Nh3 Be7 11.Ng5 1-0 (31) Carlsen,M (2843)-Wojtaszek,R (2744) Shamkir 2018 6.b3 Bg7 7.Bb2 Nf6 8.0-0-0 0-0 9.Kb1 White's argument goes something like this: the knight is not necessarily worse on g1 than on d4, where it often needs to spend another tempo in the Sicilian to go to e2 or b3. I prefer to use the two saved tempi for Qxd4 and Qd2, and place my queen in the right square. In addition — and this is why the Carlsen Variation is so special — I can put my bishop on b2, giving my king additional protection. Qa5 10.Nge2 e5!? a strange move that locks the bishop and removes it from the game. On the other hand, Nf4 and Nfd5 are prevented, so the knight on e2 is also bad. In addition, Black can now put the light-squared bishop on e6. 11.f3 Rd8 In case of the immediate 11...Be6 the players agreed that after 12.Nd5 Qxd2 13.Rxd2 White might have a slight advantage. Bxd5 If 13...Rfd8?! White has the trick 14.Nxf6+ Bxf6 15.Nf4! at his disposal. Bg5 16.Nxe6 fxe6 16...Bxd2?! 17.Nxd8 Rxd8 18.Bc4± 17.Rd1 14.exd5 Ne7 15.c4 might still be ok for Black, but MVL decided to avoid this structure. 12.Nd5 12.g4 Be6 13.g5 Nh5 14.Nd5 Qxd2 15.Rxd2 is more exciting than the game's continuation: White threatens Nc7, and also has the position threat of Ng3. Rac8 16.Ng3 Nf4! 16...Nxg3? 17.hxg3± 17.Nxf4 exf4 18.Bxg7 Kxg7 19.Ne2 White wins the pawn on f4, but Black counters with d5! is sufficient 12...Qxd2 12...Nxd5 is less accurate (Vachier-Lagrave), because the black black in some variants is good on f6. The reason: Td8 is covered, as shown in the following sequence: 13.Qxa5 Nxa5 14.Rxd5 Nc6 15.Nc3 Be6 16.Rd2 Nd4 17.Nb5 Nxb5 18.Bxb5 d5 19.Rhd1 13.Nxf6+ Bxf6 14.Rxd2 Bg5 14...Be6?! 15.Nf4! 15.Rd1 Be6 and both players agreed that Black does not have any problems here. 16.Nc3 Nd4 17.Bd3 Rac8 18.Rhf1 18.Nd5 would be the last chance for Nakamura to create something in the position. Bxd5 19.exd5 Nf5 20.Rde1 Bd2 21.Re2 Bc3= Nothing at all. 18...Nc6 19.a3 Ne7 20.Ne2 Be3 21.h3 21.f4 Bg4!= Keep the position in balance! 21...g5 22.a4 Black can now expand, but MVL overlooks the urgency to stop the next move Nakamura could have played. However, f6?! is generally useful, but too slow here. 22...a6! prevents the advance. 23.c4?! and now Nakamura wanted instead 23.Rh1 Ng6 24.g3 maintaining the balance. Visually, Black is great, but it will not be easy to make progress. 23...b5 is strongly countered by 23.c4! and "the excitement is over" (MVL). Ng6 24.Bc1 Bxc1 25.Nxc1 h5 26.Rf2 h4 27.Rfd2 Kf7 28.Ne2 Ke7 29.Kb2 Nf4 30.Nc3 a5 31.Bf1 b6 32.Bd3 Rc5 33.Bc2 Rc7 34.Re1 Rc5 35.Nd1 Rc6 36.Ne3 Rc7= 37.Red1 Rc6 38.Bd3 Rc7 39.Bc2 Rc6 40.Bd3 Rc7 41.Bc2 Rc6= "A position with fortresses for both sides", the players agreed and agreed to a draw. ½–½
