1.e4 c5 2.Ne2 { Carlsen used this Anti-Najdorf line back in 2010. } 2...d6 3.Nbc3 a6 4.g3 g6 5.Bg2 Bg7 6.d4 cxd4 7.Nxd4 Nf6 { Now a Fianchettoed Dragon appears. } 8.O-O O-O 9.b3 Nc6 ( { Black can also start with } 9...Bg4 10.Qd2 Nc6 11.Nxc6 bxc6 12.Bb2 Qa5 13.h3 Be6 14.Rad1 { with approximate equality in Landa,K
(2596)-Shneider,A (2532) Cappelle-la-Grande 2007 } ) 10.Nxc6 bxc6 11.Bb2 Qa5 { Technically speaking this is a novelty, but as we have seen from the game Landa-Shneider from above, this is not a new idea. Kovchan preferred instead: } ( 11...Nd7 12.Qd2 a5 13.Na4 Bxb2 14.Nxb2 f6 { although White seems a tad
better here to me, Hansen,M (2165)-Kovchan,A (2571) Copenhagen 2010 } ) 12.Na4 Bg4 13.Qe1 { In the case of: } ( 13.Qd3 { Nakamura would have probably played } 13...Qh5 { again. Although } ( 13...Nd7 14.Bxg7 Kxg7 { should be also playable, as in the aforementioned game by Kovchan. } ) ) 13...Qh5 { A very risky decision. Although one can
easily understand why Nakamura did not choose the worse endgame after } ( 13...Qxe1 14.Rfxe1 Nd7 { against Carlsen. } ) 14.f3 { An ambitious approach. Carlsen
wants to exclude the black queen from the play. } ( { Simpler was } 14.e5! dxe5 ( { Black loses a pawn in the line } 14...Nd7 15.exd6 exd6 ( 15...Bxb2 16.dxe7 ) 16.Bxg7 Kxg7 17.Qc3+ ( { But not } 17.Bxc6 Rac8 18.Bxd7 Bxd7 { when Black has
plenty of play on the light squares, or equality after } 19.Qd1 Qxd1 20.Rfxd1 Bxa4 21.bxa4 Rxc2 ) 17...Qe5 18.Qxe5+ Nxe5 19.f4 ) 15.Qxe5 Qxe5 16.Bxe5 Nd5 17.Rfe1 ) 14...Bh3 15.g4 Qh6 16.Rd1 { Now Bb2-c1 is a deadly threat, thus } ( 16.Bc1 g5 17.Bxh3 Qxh3 18.Bxg5 { would be
met with } 18...Nxg4! 19.fxg4 Bxa1 20.Qxa1 Qxg4+ 21.Kh1 Qxe4+ { when Black is on
top. } ) 16...g5 { is forced. However after } 17.Bc1 { Black's position seems very suspicious. Still, Carlsen might have
done better had he played: } ( 17.Qe3 { instead, a move that prevents Black's
activity in the line } 17...Bxg2 18.Kxg2 Qg6 19.Nb6! { The key move that keeps an
eye on the d5 square. } 19...Rad8 { And now } ( { Not } 19...Rab8? 20.Bxf6 Bxf6 21.Nd7 ) 20.Bc3 { After } ( 20.c4? Nxg4 { drops a pawn instead. } ) ( 20.Ba1 { is also possible though. } ) 20...d5 { White has a choice between } 21.e5 ( { And } 21.Bxf6 Bxf6 22.exd5 cxd5 23.Nxd5 Qxc2+ 24.Rd2 Qg6 25.Rff2 ) 21...Nd7 22.Nxd7 Rxd7 { with advantage for the first player in either line. } ) 17...Bxg2 18.Kxg2 Qg6 19.h4 { It was not too late to prevent the central break with } ( 19.Qe3 h6 20.Nb6 Rab8 21.Nc4 { with the idea } 21...d5? 22.Ne5 ) 19...gxh4 20.Qxh4 d5! { Nakamura seizes his chance. } 21.g5?! { Carlsen continues to
play for domination, but his forces do not seem active enough. Instead: } ( 21.exd5 cxd5 ( { Or } 21...Qxc2+ 22.Rd2 Qg6 23.dxc6 Rac8 ) 22.c3 Rac8 { would have
left the worst behind for Black. } ) 21...dxe4 22.f4 e6! { Missed by Carlsen. Perhaps White was hoping for an attack in the lines: } ( 22...h6 23.f5 hxg5 24.Bxg5 Qh7 25.Qxh7+ Kxh7 26.Rh1+ ( 26.Nb6 Rad8 27.Rh1+ Kg8 28.Rdg1 { is also good for White. } ) 26...Kg8 27.Bxf6 Bxf6 ( 27...exf6 { looks ugly,
self-trapping the bishop. } ) 28.Nb6 Rad8 29.Nd7 Rfe8 30.Kf2 { and Black can
hardly survive here. } ) 23.c4 { Takes away the d5 square from Black. That is important in the line } ( 23.Kf2 Nd5 24.c4 Nb4 ) 23...Rfd8 { Simple and good.
Clearly worse was } ( 23...h6 24.Nc5 hxg5 25.fxg5 Nh7 26.Qxe4 { with an edge
for White. } ) 24.Rde1 ( { Now } 24.Nc5 { is met with } 24...Bf8 ) 24...Ne8 { Black's queen survived. Black has won a pawn and has some juicy outposts for the knight. } 25.Nc5 { Active play is doomed to failure. } ( 25.f5 exf5 26.Qh3 Nd6 27.c5 Nb5 28.Rxf5 Rd3 ) 25...Nd6 26.Qf2 f5 27.Bb2 Nf7 { Also good was } ( 27...Bxb2 28.Qxb2 Nf7 29.Qf6 Qxf6 30.gxf6 Nh6 31.Nxe6 Rd6 { with a clear edge in the endgame. } ) 28.Bxg7 Kxg7 29.Qg3 ( { More resilent seemed } 29.Re3 { with the idea to double the heavy pieces along the h-file. } ) 29...Rd6 30.Rd1 Rad8 31.Rxd6 Rxd6 { In addition to the extra pawn, Nakamura has added open files for his heavy pieces. The decisive counter-attack is just around the corner. } 32.Qc3+ Kg8 33.Rf2 Qh5 34.Qh3 Qd1 35.Qe3 e5 36.Qg3 ( { Or } 36.fxe5 Nxe5 37.Rxf5? Qg4+ ) 36...Rg6 37.Kh2 exf4 38.Qxf4 Qh5+ 39.Kg1 Qd1+ 40.Kh2 Qh5+ 41.Kg1 Nxg5 42.Qb8+ Kg7 43.Qe5+ Kh6 44.Qf4 Qd1+ 45.Kh2 ( 45.Rf1 Qd4+ ) 45...Qd4 { The long diagonal is secured; the king may run away from the pin. } 46.b4 Kg7 47.Qc7+ Kh8 48.Qc8+ Rg8 49.Qxf5 Nf3+ 50.Kh3 Qd6
