Carlsen wins game 6 despite the huge mutual oversight

The 6th game of the World Championship match in Sochi would have been a very good and consistent victory by Carlsen had there been no mutual oversight on move 26 when both players missed a very simple tactics. What can be said about this? Well, even the greatest players are just humans, and, as the Latin saying goes, 'Errare Humanum Est'.

Sicilian Defence
1.e4 c5 2.Nf3 e6 3.d4 (Magnus has tried 3.g3 in the 4th game) 3...cxd4 4.Nxd4 a6 (this variation is named after Soviet master Kan) 5.c4 Nf6 6.Nc3 Bb4. One of Anand's seconds in the match, Polish GM Grzegorz Gajewski, has this line in his repertoire.

7.Qd3!? Nc6. Many other replies are possible as well. If 7...Qc7 then White has an important idea 8.a3 Bxc3+ 9.Qxc3, and the pawn is poisoned: 9...Nxe4? 10.Nb5! axb5 11.Qxg7 Rf8 12.Bh6 Qc5 13.f3. The game Anand - Svidler (Monaco 2005, blindfold) saw 7...d5 which is in fact not the most popular move.
8.Nxc6 dxc6 9.Qxd8+!? Instead of this quite natural exchange, 9.e5 is usually played. For instance, Alexei Shirov chose it this year against the expert of this line Normunds Miezis in their rapid game.
9...Kxd8 10.e5!

10...Nd7. The game Flores Rios - Lemos (Villa Martelli 2008) went 10...Ne4 11.a3! Bxc3+ 12.bxc3 Kc7 (12...Nxc3?! 13.a4! is much better for White) 13.Be3 b6 14.Bd3 Nc5 15.Bxc5 bxc5 16.0–0–0 with the stable advantage for White, although maybe not decisive one.
11.Bf4 Bxc3+. This capture wasn't necessary. Black can also play 11...Ke7, for example: 12.0–0–0 Ba5 13.Ne4 Bc7 14.Nd6 Rd8, and now White can prevent 15...Nxe5 by 15.Re1!. 11...f5 makes sense too, although White's position is preferrable anyway. In general, Anand's opening choise is hard to explain, as the endgame isn't promising for Black at all; the only thing Black could hope for is to save the game after a long struggle.
12.bxc3 Kc7.

13.h4 (obtaining long-term advantage on the king's side) 13...b6 (13...h5!? might be the lesser evil - A.D.) 14.h5 (14.Rh3!? was also possible; to me, Carlsen's move looks more precise, as there is no 14...h5 anymore - A.D.) 14...h6. If 14...Bb7 then the pawn march could go on: 15.h6, and after 15...g6 White prepares f2-f4-f5 slowly but surely.
15.0–0–0 Bb7 16.Rd3 c5 17.Rg3! Rag8 18.Bd3 Nf8 19.Be3! This subtle retreat is the prophylaxis against g7-g5. However, Anand decided to move his g-pawn anyway.

19...g6?! 'He can go something like 19...Bc6 and then 20...Be8, but anyway it's really not very nice' - Carlsen.
20.hxg6 Nxg6 21.Rh5! Bc6 22.Bc2 (the h6-pawn won't escape, so White is trying to reach the optimum setup) 22...Kb7 23.Rg4 a5 24.Bd1 Rd8 25.Bc2 Rdg8

26.Kd2?? Having repeated the moves once, the World Champion makes a horrible blunder. As he mentioned at the press conference, the same idea of bringing the king to the center could be realised by 26.Kd1!?. Besides, White had some other good moves as well.
26...a4?? A very simple combination 26...Nxe5! would have changed the decorations. Incredibly, Anand with his brilliant eye for tactics misses this strike too. Carlsen: 'I was extremely lucky'. After 27.Rxg8 Nxc4+ 28.Kd3 Nb2+! Black is just 2 pawns up; even though the h6-pawn falls inevitably, White would have struggle in pains for a draw.
27.Ke2 a3! 28.f3! Rd8 29.Ke1!? (Carlsen rejected 29.Bxg6 fxg6 30.Rxg6 Be8 31.Rg7+ Rd7 32.Rxd7+ Bxd7 with definite drawing chances for Black) 29...Rd7 30.Bc1 Ra8 (30...Rhd8!?) 31.Ke2 Ba4!? According to Carlsen, Black could resist better by 31...Ne7, which in fact isn't so certain.

32...Bc6?! Black had to give up the exchange: 32...Ka7! 33.Bxa8 Kxa8. Now White doesn't have a good way to stop ...Rd1. The following lines demonstrate that the fight is going on, even though White is better: 34.Bxa3 Rd1 35.Rxh6 Ra1 36.Rg5 Rxa2+ 37.Ke1 Rxa3 (or maybe 37...Ra1+ 38.Kf2 Rxa3 39.Rh7 Be8 40.Rxg6 fxg6 41.Rh8 Kb7 42.Rxe8 Rxc3) 38.Rh7 Rxc3 39.Rxf7 Bc2 40.Rf6 Rxc4 41.Rxe6 Kb7 42.Rgxg6 Bxg6 43.Rxg6 b5.
33.Bxg6 fxg6 34.Rxg6 (now Black is in real trouble) 34...Ba4 35.Rxe6 Rd1 36.Bxa3! Ra1 37.Ke3. The position is winning for White, as he has collected nearly all the black pawns.

37...Bc2? (37...Rxa2 or 37...Re8 would have been more persistent) 38.Re7+. 1–0 Anand resigned due to the coming 39.Rxh6. 'Usually you feel happy when you win, today it was mostly relief. I think it was a good game to some point, and then, I mean, when you get such a gift you just feel massive relief' - Carlsen.

After 6 games, the match score is 3.5 - 2.5 to Carlsen. Tomorrow, November 16th, is a day-off; game 7 will start on November 17th at 12:00 GMT. Magnus Carlsen will be White again, as the players switch the colours halfway through the match.
