1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3
The starting position of the Closed Spanish.

Swinging the knight via b8 to d7 to protect the pawn on e5 is an idea of a talented Hungarian master Gyula Breyer. It dates back to 1920. At the end of the 19th century in similar positions, the first world champion William Steinitz and his rival, Mikhail Chigorin, also protected the pawn on e5 with a knight, but they did it rather clumsily using the knight from f6.

10.d4 Nbd7 11.Nbd2 Bb7
We can see the elegance and flexibility of Breyer's setup: the knight on d7 protects the center, the bishop on b7 attacks it. The c-pawn is not hindered and can advance any moment. In addition, black may also strike in the center with d6-d5.

12.Bc2 Re8 13.a4
[White is at a crossroads. Swinging the knight to the kingside 13.Nf1 Bf8 14.Ng3 was the usual popular plan, but after 14... 14...g6 white needed to open a second front and played 15.a4 c5 (Blacks later realized that keeping the center flexible with 15...Bg7 16.Bd3 c6 is not a bad idea.) 16.d5 and with the center closed, white could use his space advantage to prepare a combined attack on both wings. The first game between Bobby Fischer and Boris Spassky in 1992 comes immediately to mind.]

13...Bf8 14.Bd3 c6 15.b4 Rc8!?
A new, good waiting move. Carlsen previously played 15...Nb6 against Anand, clarifying the matters on the queenside immediately. [15...Nb6 16.axb5 (16.a5 Nbd7 17.Bb2 g6 18.c4 exd4 19.Bxd4 (19.cxb5 cxb5 20.Bxd4 Ne5 21.Bc2 Nh5 22.Qb1 Nf4 23.Ra3 Rc8 24.Rc3 Rxc3 25.Bxc3 Bg7 26.Qa1 Qc7 27.Re3 Nxf3+ 0-1 Ornstein,A (2405)-Reshevsky,S (2460)/Reykjavik 1984) 19...Ne5 20.Bb6 Qd7 21.Qc2 Nxd3 22.Qxd3 c5 23.Rab1 Bc6 24.bxc5 dxc5 25.Qc2 Qb7 26.cxb5 axb5 27.Bxc5 Nxe4 28.Bxf8 Nxd2 29.Qxd2 Rxf8 30.Nh4 Qd7 31.Qc3 Rfd8 32.Re3 Rac8 33.Qa3 Qd6 34.Nf3 Qd5 35.Rbe1 Rb8 36.Re5 Qd7 37.Re7 Qf5 38.Ne5 b4 39.Qb2 Bd5 40.Ng4 Qg5 41.Nf6+ 1-0 Sutovsky,E (2665)-Filippov,A (2609)/Khanty Mansiysk 2010.) 16...axb5 (16...cxb5 17.d5!

16.axb5 cxb5 17.Bb2
White is ready to close the center with 18.d5 and black has to react.

And just like that black equalizes. After the pawns disappear from the center, black's pieces will be well placed.

[After 18.dxe5 dxe4! 19.Nxe4 Nxe5 20.Nxe5 Rxe5 21.Nxf6+ Qxf6 black has a slight edge.]

18...exd4 19.Rxe8
[After 19.Nxd4 Nxd5 the black pieces have a larger playground.]

19...Qxe8 20.c4
By advancing the c-pawn Anand can eliminate all pawns on the queenside. Everybody expected a quick draw.

20...bxc4 21.Nxc4?!
[Anand gambles and sacrifices a pawn. After 21.Bxc4 Nb6 22.Bxa6 Bxa6 23.Rxa6 Nbxd5 24.Nxd4 Bxb4 there is not much to play for.]

21...Nxd5 22.Nxd4 Nxb4 23.Nf5
(Anand moves his knight to an aggressive position, hoping for some attacking chances. But the legendary grandmaster David Bronstein claimed that the bishop on f8 can defend well against the knight on f5. Let's see...)

23...Nxd3 24.Qxd3 Be4?
"A huge oversight," said Carlsen, but fork is a fork and it could be a choice of many club players since Anand's little combination is not obvious. [Still, Magnus should have played 24...Qe6! 25.Ncd6 Rc5 26.Nxb7 Rxf5 with advantage.]

25.Qd4 Bxf5?!
[Sacrificing the queen after 25...Qe6!? 26.Ncd6 Rb8 27.Re1 Bxf5 28.Rxe6 Bxe6 give black good chances to hold.]

Forking the whole army of black pieces, Anand gets a strong pressure.

[26...Bxd6?? 27.Qxg7# ; After 26...Qe6 27.Nxc8 Nc5 28.Ba3 Qxc8 (28...Nb3 29.Qd8 Qxc8 30.Rd1 h5 31.Bxf8+- ) 29.Rc1 Be7 30.Bxc5 white should win.]

27.Nxf5 f6?
Black can't recover after this mistake. Instead, Magnus had two possiblities to stay in the game: [27...Qf6 28.Qxf6 Nxf6 29.Bxf6 gxf6 30.Rxa6 is unpleasnt for black, but the material is reduced and there is hope, for example 30...Rc5 31.g4 (31.Rxf6 Bg7= ) 31...h5 32.Rxf6 hxg4 33.hxg4 Rc4 34.f3 Rc2 ; The computers want to fight back with 27...Rc6 28.Nxg7 Qb6! forcing the exchange of queens.]

28.Rd1 Rc2
[Carlsen defends aggressively. He probably didn't like that after 28...Rc7 29.Qd5+ Kh8 30.Qf7 his pieces would be pinned down.]

It didn't take Anand long to claim a big advantage.

[29...Kh8 30.Nf7+ wins.] Magnus should have made it more difficult for white with

30.Qg4+ Bg7?!
[Magnus should have made it more difficult for white with 30...Kh8 31.Rxd7 Qxd7 32.Bxf6+ Qg7 33.Bxg7+ Bxg7 although after 34.Qe6 Bf8 35.Qf5 Rc1+ 36.Kh2 Bg7 37.Qe6 Ba1 (37...Bf8 38.Qe5+ Kg8 39.Qg3+ Kh8 40.Qb8 Kg8 41.Qb3+ Kh8 42.Qb2+ wins the rook.) 38.Qe8+ Kg7 39.Qe7+ Kg8 40.f4 white has winning chances.]

31.Qe6+ Kh8 32.Rxd7 Qf8 33.Ba3?
[A ghost of the famous game Botvinnik-Capablanca, AVRO 1938, where similar deflecting sacrifice was decisive. But here Anand floats away from a direct win: 33.Rf7! Qc8 (33...Qb8 34.Re7 Rc8 35.Rxg7 Qxb2 36.Qf7 Qa1+ 37.Kh2 Qe5+ 38.f4 Qxf4+ 39.Rg3 Qxg3+ 40.Kxg3 Rg8+ 41.Kh4 Rxg2 42.Qf8+ Rg8 43.Qxf6+ Rg7 44.Qe5! a5 (44...Kg8 45.Qe8# ) 45.Kh5 a4 46.Kxh6 a3 47.Qxg7# ) 34.Qe7 Rc1+ 35.Kh2 Qb8+ 36.g3 Rc2 37.Bd4 Qg8 38.Qxf6! Bxf6 39.Bxf6+ Qg7 40.Rf8# ]

[33...Qxa3 is not entirely clear, for example 34.Rd8+ Qf8 (34...Bf8 35.Qxf6+ Kg8 36.Qe6+ Kh8 37.Qf7 Rxf2 38.Kxf2 wins) 35.Rxf8+ Bxf8 36.Qxf6+ Kg8 black can try to fight.]

Black will have a hard time to protect the last two ranks and the f-pawn.

34...Qe8 35.Qa7! Qg8
[Black is forced to play passively. After 35...Qe1+ 36.Kh2 Qe5+ 37.g3 Qe8 38.Rxg7 wins.]

[Anand could have cut off the black rook with 36.Bc5! and only after 36...Re2 37.Be7 threaten to win with 38.Rd8.]

36...Rc8 37.Qa6 Qe8 38.Ra7 Kg8 39.Qe6+
[But not 39.Bxf6? Bxf6 40.Qxf6 Rc1+ 41.Kh2 Qb8+ and black (!) wins.]

39...Kh8 40.Qa6 Kg8 41.Qe6+
The time control is over and Anand can assess the position. Black's pawns on the kingside are shattered, but can white mount a successful siege of the pawn f6 and win it? The problem is that black can't do anything. Carlsen has to wait for Anand to demonstrate how to set up the pieces the best way.

41...Kh8 42.Kh2 Rc6
[After 42...Ra8 43.Rc7 white keeps the pressure on.]

43.Qb3 Rc8 44.Bd6 Qg6 45.Qb7 Rd8 46.Bg3 Rg8 47.h4 Qf5 48.Qc7 Qd5 49.Ra5 Qe4 50.Qd7 Qc4 51.Qf5 Qc8 52.Qf3 Qd7 53.Bf4 Qf7 54.g3 Re8 55.Be3 Rg8 56.Ra6 Re8 57.Ra7 Re7 58.Qa8+ Qf8 59.Ra6 Re8 60.Qc6 Rc8 61.Qf3 Qf7 62.Ra7 Qe6 63.Qb7 Qg8 64.Bf4 Rd8 65.Qa6 Re8 66.Rc7 Ra8 67.Qc6 Re8 68.Be3 Rb8 69.Bd4
Anand found the ideal position. White combines the attack on the pawn on f6 with the threats on the 8th rank.

[69...Rf8 70.Re7 Rf7 71.Re6 f5 (71...Rf8 72.Rxf6! Rxf6 73.Qxf6 wins.) 72.Qc3 f4 73.Bxg7+ Rxg7 74.Qe5 wins.]

70.Qc3 Re8 71.Rc6
Picking up the pawns.

[71...f5 72.Rc7 wins.]

72.Bxf6 Rf8
[Black also loses after 72...Kg8 73.Bxg7 Qxg7 74.Qd2 h5 75.Rc5+- ]

73.Bxg7+ Qxg7 74.Qe3 Qb2 75.Kg2 Qb7 76.Qxh6 Qf7
[76...Rc8 77.Qf6+ Kg8 78.Qe6+ wins.]

77.Rc2 1-0
