1.e4 e5 2.f4 [The King's gambit is one way to avoid the dreaded Petroff defense 2.Nf3 Nf6 ]

2...d5
[In 2004, when he was making his first steps toward stardom, Carlsen as Black played against GM Alexei Fedorov in Dubai 2...exf4 3.Nf3 g5 4.h4 g4 5.Ne5 d6 6.Nxg4 Nf6 7.Nxf6+ Qxf6 8.Nc3 Nc6 9.Bb5 Kd8 10.Bxc6 bxc6 11.d3 Rg8 12.Qf3 Bh6 13.Qf2 Rb8 14.Ne2 Rxb2 15.Bxb2 Qxb2 16.0-0 Qxc2 17.Nxf4 Qxf2+ and the players agareed to a draw since the forced variation: 18.Rxf2 Bg7 19.Rc1 Bd4 20.Rxc6 Rg4 21.Nd5 Bb7 22.Rc4 Bxf2+ 23.Kxf2 Rxh4 24.Nxc7 Rh5 does not give much to either side.]

3.exd5 exf4
A popular way to defuse the tension in the center.

4.Nf3 Nf6
[In his new book "Starting Out: Open Games," GM Glenn Flear brings back the move 6...Bd6. It was played in the famous game Boris Spassky-David Bronstein, Leningrad 1960, and the final few moves were reproduced in the James Bond movie "From Russia with Love." For years nobody touched it, but Flear is convinced that after 4...Bd6 5.Bb5+ (or 5.Nc3 Ne7 6.d4 0-0 7.Bd3 Ng6!? (7...Nd7?! 8.0-0 h6? 9.Ne4! Nxd5 10.c4 Ne3 11.Bxe3 fxe3 12.c5 Be7 13.Bc2! Re8 14.Qd3 e2? 15.Nd6!? Nf8?! 16.Nxf7 exf1Q+ 17.Rxf1 Bf5 (17...Kxf7 18.Ne5+ Kg8 19.Qh7+! Nxh7 20.Bb3+ Kh8 21.Ng6# ) 18.Qxf5 Qd7 19.Qf4 Bf6 20.N3e5 Qe7 21.Bb3 Bxe5 22.Nxe5+ Kh7 23.Qe4+ 1-0 Spassky,B-Bronstein,D/Leningrad 1960/URS-ch (23.Qe4+ g6 24.Rxf8! wins. It was one of Spassky's finest achievements and a disaster for Black. ) ) 8.0-0 c6 ) 5...c6 6.dxc6 Nxc6 7.d4 Nge7 8.0-0 0-0 9.c4 Bg4 Black has active piece play against White's center.]

5.Bc4!?
The Bishop move is now preferable to 5.Bb5+ or 5.Nc3. [5.Nc3 Nxd5 6.Nxd5 Qxd5 7.d4 Bg4!? (The game Reti,R-Nyholm,G, Baden 1914, went 7...Bd6 8.c4 Qe6+ 9.Kf2 c5 10.Bd3 Qh6 11.Re1+ Kf8 12.Qe2 Bd7 13.b4! with clear advantage to White. ) 8.Bxf4 Nc6 9.Be2 0-0-0 10.c3 Bd6 11.Bxd6 Qxd6 12.0-0 f6 with equal chances, Chigorin,M-Tarrasch,S,St Petersburg 1893 ; 5.Bb5+ ]

5...Nxd5 6.0-0 Be7
[Black can invite an interesting gambit with 6...Be6 7.Bb3 Be7 8.c4 Nb6 9.d4 Nxc4 but White seems to have good compensation for the pawn. The game Shulman-Onischuk, Kansas 2003, continued 10.Nc3 c6 (10...Na5!? is not bad either 11.Bxe6 fxe6 12.Qe2 Nbc6 13.Bxf4 Nxd4= ) 11.Bxf4 0-0 12.Qe2 b5 13.a4 Qb6 with roughly equal chances.]

7.Bxd5!?
Why would White give up this wonderful Bishop, which did great damage in many King's gambit games? The answer is speed in development. White gets his pieces quickly into play, dominates the center and, in general, enjoys more space.

7...Qxd5 8.Nc3 Qd8
The Queen moves like a yo-yo, but it is the safest retreat. By protecting the pawn on c7, Black will have more time to develop his light pieces. Holding onto the pawn seems dangerous and definitely not in style of the Chinese grandmaster. [It could get wild after 8...Qf5 9.d4 0-0 10.Ne5 g5 11.Nd5 with a possible piece sacrifice on f4.]

9.d4 0-0 10.Bxf4 Bf5
[Wang develops his Bishop and takes the square d3 from the white Queen. But 10...c6 11.Qd3 Na6 12.Rae1 Be6 is a good, playable alternative.]

11.Qe2!?
[Carlsen connects the Rooks and Black has to be aware of a timely 12.Qb5. In the game Fedorov-Svidler, Smolensk 2000, Black was able to secure the light squares after 11.Qd2 c6 12.Kh1 Bb4 13.a3 Bxc3 14.Qxc3 Qd5 15.Qd2 Nd7 16.b3 b5 17.Rac1 Nb6 He later outplayed his opponent and won in 41 moves.]

11...Bd6?!
Exchanging pieces in a worse position is a common ploy of good defenders, but here it leads to more yo-yo moves by the black Queens and helps Carlsen to improve his position. [Wang probably didn't like 11...c6 12.Rae1 Re8 (12...Bd6 13.Bxd6 Qxd6 14.Ne4 ) 13.Bg5 with White's edge.]

12.Bxd6 Qxd6 13.Nb5!
Improving the "marriage" between the c-pawn and the white Knight. David Bronstein believed that the Knight behind the pawn is a good marriage and in front of the pawn a bad one.

13...Qd8
(The safest retreat. [13...Qb6? 14.Qe5 Bxc2 15.Nxc7 Nd7 16.Nxa8 and White should win.; 13...Qd7? 14.Ne5 Qc8 15.Rxf5 Qxf5 16.Rf1 Qc8 17.Qc4 with a decisive attack.]

14.c4 a6
[Black doesn't want to engage his c-pawn too soon, but 14...c6!? 15.Nc3 Re8 16.Qd2 Nd7 is a better defensive set-up.]

15.Nc3
Now the knight is behind the pawn and according the legendary GM David Bronstein, it constitutes a good marriage. White controls most squares in the center and can turn it into a space advantage.

Diagram

21.d5!
Crossing the equator, the line that splits the board in half horizontally, dividing both armies. Carlsen intends to advance the passed d-pawn as far as he can.

21...Nf6?!
[(Black should have exchanged the pawn immediately to keep more pieces in play. After 21...cxd5 White has to retake with the pawn 22.cxd5 (22.Nxd5?! Rxc4! 23.Qa7 Re4 24.Qxb7 Rxe1+ 25.Nxe1 Be4= ) 22...Qc7 23.Qd4 Qd6= ]

22.Qd4 cxd5 23.Nxd5!
Threatening 24.Ne7+, White forces the knight exchange, eliminating one blocker.

23...Nxd5 24.cxd5 Qd6
The Queen is usually a poor blocker, but Black doesn't have anything else handy.

25.Ne5 Re8
[The immediate 25...Rd8 was possible, but Black had a reason to lure the white rook on e3. However, Wang should have clarified the position with 25...f6! 26.Nxg6 (26.Nc4? Qb4!-+ ) 26...hxg6 for example 27.Re6 [Otherwise Black plays 27...Rd8.] 27...Rc1+ 28.Kf2 Rc2+ 29.Kf3 Qd7 (Or 29...Qh2 30.Qg4 Kf7 (30...g5? 31.d6 Qg1 32.Re8+ Kf7 33.Qh5+ g6 34.Qh7+ Kxe8 35.Qe7# ) 31.d6 (31.Rb6 Qc7= ) 31...Qg1 32.Re7+ Kf8 33.Re8+ Kxe8 34.Qxg6+ Kd7 35.Qxc2 Kxd6= ) 30.Kg3= ]

26.Re3 Rd8 27.Nc4 Qf6 28.Re5!?
[Carlsen decides to keep the Queens on the board. After 28.Qxf6 gxf6 the White Rook can't protect the d-pawn since the square d3 is taken and after 29.Re7 Bb1!? 30.a3 (30.a4 b5 31.axb5 axb5 ) 30...b5 Black has good drawing chances.]

28...h6
[(The computers want to play 28...b5 29.Na5 h6 30.Nb7 Rb8 31.Nc5 (31.d6? Rxb7 32.d7 Rxd7 33.Re8+ Kh7 34.Qxd7 Qxb2= ) 31...Qd6 32.b4 the position looks better for White. With the help of tactical tricks Carlsen is now able to march his d-pawn forward.]

29.d6!
Did Black overlook this advance?

29...Bf5
[After 29...b5 30.d7! bxc4? 31.Re8+ Kh7 32.Qxf6 gxf6 33.Rxd8 wins.]

30.Nb6! Be6
[Black still can't touch the d-pawn: after 30...Rxd6 31.Nd5! wins the Exchange or the Bishop after 31...Qg5 32.Rxf5! Qxf5 33.Ne7+ ; Black loses after 30...Qxd6? 31.Re8+! ; Black could have considered to maneuver the Bishop to the diagonal h1-a8: 30...Bd3 31.d7 Bb5 32.a4 Qf1+ 33.Kh2 Bc6 with some hope to survive.]

31.d7!
Black is in a terrible squeeze and Carlsen has time to improve his pieces.

31...Kh8 32.a4 g6 33.Qc3 Kg7 34.a5 h5 35.h4 Rxd7?!
[This could be Black's best practical chance to avoid a slow death. After 35...Kg8 36.g3 Kg7 37.Rc5 Qxc3 38.Rxc3 Kf6 39.Rc7 White has excellent winning chances, for example 39...Ke7 40.Rxb7 Bxd7 41.Ra7+- Ke8 42.Rxa6 Bb5 43.Ra8 Rxa8 44.Nxa8 Kd7 45.Kf2 Kc6 46.Ke3 Bf1 47.Kd4 Kb5 48.Nc7+ Kxa5 49.Kc5 and the b-pawn runs to victory.]

36.Nxd7 Bxd7 37.Qd4 Bc6 38.b4 Bb5 39.Kh2 Ba4 40.Rd5 Bc6 41.Qxf6+ Kxf6 42.Rc5 Ke6 43.Kg3 f6 44.Kf2 Bd5 45.g3 g5?
Allowing a pretty breakthrough. Black should have waited, not allowing the white Rook to penetrate to the back rank. If the white King begins to cross to the square b6, Black can push his g-pawn, hoping to create a passed pawn on the kingside. It could be close.

46.g4! hxg4 47.h5 Be4 48.Rc7!
Supporting the passed pawn and not allowing the black King to come closer.

48...f5 49.h6 f4 50.h7 g3+ 51.Ke1 f3 52.h8Q f2+ 53.Ke2 Bd3+ 54.Ke3
Black resigned. [54.Ke3 f1Q 55.Qe8+ Kf5 56.Rf7+ wins.] 1-0
