The Russian GM has defeated Karjakin and caught up with Nakamura

More than a half of the distance is over in Tashkent where the 2nd stage of the FIDE Grand Prix series 2014/15 is taking place. In round 6, the tournament leader Hikaru Nakamura was White against Fabiano Caruana; after the opening, he made a series of quite superfluous moves and got clearly worse in the middlegame.

NAKAMURA - CARUANA

White's pawn structure is fixed while the pieces are restricted, so the Elo-favourite was probably hoping to improve his poor tournament situation (1 loss without any victories). However, Nakamura found a good practical resource, sacrificing a pawn in order to activate the pieces, the knight in particular: 30.b4!? axb3 31.Nxb3 Rxa3 32.Nd4 Rxc3 33.Qxc3. Eventually, it worked and the leader has been able to save half-a-point.

Meanwhile, Dmitry Andreikin has managed to make use of Nakamura's hitch. The Russian GM has outplayed his compatriot Sergey Karjakin and joined the American in the lead.

ANDREIKIN - KARJAKIN
Torre Attack
1.d4 Nf6 2.Nf3 e6 3.Bg5 c5 4.Nc3!? This is a very rare line (instead of habitual and solid 4.e3) which hadn't almost been seen on the top level.
4...cxd4 5.Qxd4

5...Nc6 6.Qh4 Bb4!? (not the most reliable reply, but probably Karjakin was hoping for more than just an equality) 7.e4 Bxc3+ 8.bxc3 (White's pawn structure is now broken, but he has long-term pressure on the dark squares) 8...h6 9.Bd3 d6. The castling could bump into Bxh6!? sacrifice - it looks like Sergey, after his painful loss to Jobava, didn't want to allow a similar attack. (Which, however, was exactly the thing to happen later on.)
10.Rd1 Rg8!? 11.Be3 (11.Bc1!?)

11...e5. This is the confirmation of Black's aggressive intentions, as he could force a draw by 11...g5 12.Qxh6 Rg6 13.Qh8+ Rg8. White cannot avoid the repetition as the e3-square is occupied by the bishop: 12.Qg3? g4! and the knight can't retreat because after 13...Nh5 the queen is trapped.
12.Bb5!? Qc7 (12...Qa5!? was playable instead: 13.Bxc6+ bxc6 14.0–0 Ba6) 13.Nd2 Be6 14.f3
.

14...Qa5 (a prelude to a wrong strategic plan; both 14...0–0–0 and 14...d5 would keep decent chances) 15.c4 Ke7?! 16.0–0 g5?! Black isn't in firm control at any side of the board (by the way, much due to the absence of his dark-squared bishop) to play like this.
17.Qf2. From now on, White is definitely better, and the remaining part of the game is, strictly speaking, just a confident realization of the strategic advantage.
17...Rgd8 18.h4 Nh7 19.hxg5 hxg5 20.g4!? f6 21.Kg2 (hasty 21.Nb3 Qc7 22.c5 wasn't the idea behind the previous move) 21...Nf8 22.Rh1.

22...Bf7?! If 22...Nb4?! then 23.Bxg5! fxg5 24.Qe3 (Andreikin); maybe Black had to make up his mind for 22...Qxa2, although the position after 23.c5! wouldn't be pleasant by any means.
23.Nf1! Bg6 (bringing the bishop to a totally passive position hardly gives Black more hope) 24.Bd2!? Qb6 25.Ne3 Kf7 26.Qe1 Ne6 27.Nf5

Black's position might seem solid at first glance, but in fact it is crumbling on all sides.
27...Qc7?! Other lines are: 27...a6 28.Rh6! axb5 29.Qh1!; 27...Ncd4 28.Nxd4 Nxd4 29.Ba5 Nxc2 30.Qd2 Ne3+ 31.Kg3 Qc5 32.Rde1 b6 33.Bb4 Nxc4 34.Bxc5 Nxd2 35.Bb4 - White is trapping the d2-knight and looking forward to convert his material advantage into a win.
28.c5! dxc5 29.Bc4! b5 30.Bd5 (30.Bxe6+!? Kxe6 31.Rh6 Rg8 32.Qe3 Nd4 33.c3! was also good) 30...Rac8 (if 30...Rh8 then 31.Qf2)

31.Rh6! (Black is helpless) 31...Ncd4 32.Ba5 Nxc2 33.Qh1 Qxa5 34.Rh7+. The checkmate can't be avoided, so Karjakin resigned. 1–0 (Annotated by GM M.Golubev)

The second decisive game of the day was Mamedyarov's victory as White over Kasimdzhanov. It was a tense fight where Black had had good chances at first, but started making mistakes in the sharp middlegame (22...Rad8?!; 30...Rb6?).

Four other games (including the aforementioned Nakamura - Caruana encounter) have been drawn. Gelfand - Vachier-Lagrave saw a fresh idea by Black on move 9 in the Grunfeld Defence. We would mention 14.Nb5!? as an interesting option for White. Later on, the Israeli GM lost the thread somehow and could face the difficulties had Maxime found 28...Rc2+!

Giri - Radjabov is interesting for those who are deeply into study of the Berlin Wall. 24th move by White was a novelty; two moves later, Giri missed 26.Rxc7 which could be quite unpleasant for Black.

The hero of the previous round Baadur Jobava opted for an interesting pawn sacrifice by his 12th move, yet wasn't unable to break Dmitry Jakovenko's solid defence. Moreover, it was Black who tried to play for a win at the end, even though nominally.

After 6 rounds, Nakamura and Andreikin are in the lead with 4 points each. Mamedyarov, Vachier-Lagrave, Jobava are half-a-point behind.
