Mamedyarov - Nakamura battle was the highlight of the peaceful round

Round 4 of the FIDE Grand Prix tournament in Tashkent was very peaceful. Among the 6 drawn games, the Mamedyarov - Nakamura encounter was the most fighting and tense. Both opponents played extremely well.

MAMEDYAROV - NAKAMURA
Queen's Gambit Declined
1.d4 d5 2.c4 e6 3.Nc3 Be7 4.cxd5 exd5 5.Bf4 c6 6.e3 Bf5 7.g4 Be6 8.h4 Nd7 9.h5

9...Nh6. This line was introduced into practice back in 1985, in the Kasparov-Karpov match. 10.Be2 Nb6 11.Nh3 (the aforementioned historical game saw a less aggressive move - 11.Rc1) 11...g5 12.hxg6 hxg6. After a supposedly calm opening, the game has transposed into a complicated position with the knights unusually located on the h-flie. (The position, as well as the whole game, reminds the editor of Chess960 a little. By the way, Fischer's version of chess has been spoken of approvingly by both players, especially by Nakamura - CN.)

13.Be5!? An improvement over Nakamura - Aronian (Sao Paulo/Bilbao, 2011) where 13.Bg3? could be met by 13...Nxg4! 14.Bxg4 Qd7!. In case of 13.f3, Black has 13...Bh4+! followed by g6-g5 (Vaisser - Timoscenko, Tashkent 1987). The engines suggest somewhat unexpected 13.a4!?. 13...f6! 14.Nf4! A very interesting piece sacrifice.

14...fxe5 After more yielding 14...Bf7 15.Qc2 fxe5 16.Nxg6 Bxg6 17.Qxg6+ Kd7 18.Rxh6 (18.dxe5!?) 18...Rxh6 19.Qxh6 exd4 20.exd4 White seems to be a little better.
15.Nxg6! (not 15.Nxe6 Qd6 16.g5 Qxe6 17.gxh6 e4! with better chances for Black) 15...Rg8?! If 15...Kd7 then 16.dxe5! is very strong; the crucial line was 15...Rh7! 16.dxe5 (16.Nxe5 Bh4!), with double-edged complications after 16...Qd7 or 16...Bg8.
16.Nxe7 Qxe7 17.Rxh6 e4. Black is a pawn down, but the g4-pawn is weak. Stiill, White has some advantage.

18.a4 (a logical alternative is 18.Kd2!? 0–0–0 19.Qg1!) 18...Nd7. In turn, Black could opt for a more resolute continuation: 18...0–0–0!? 19.a5 Nc4 (19...Nd7?! is worse due to 20.a6 b6 21.Qa4 Nb8 22.Nb5! Rd7 23.Rc1 Kd8 24.Nc3) 20.a6 b5 (20...b6?! 21.Qc2!) 21.b3 Nd6.
19.Qb3?! (both 19.a5 and 19.Kd2 were more promising) 19...Nf6! Noticing the trap: 19...0–0–0? 20.Nxe4. After the text move, the position is roughly equal as Black is getting the pawn back without many troubles.
20.Rc1 (or 20.a5 Bxg4 21.a6 b6) 20...Bxg4
.

21.Rxf6!? The compensation will be sufficient, but no more than that. 21...Qxf6 22.Qxb7 Rd8 23.Qxa7 Rf8!? 24.Nd1 Bxe2 25.Kxe2 Qd6!? 26.Rc5 (or 26.b4!? Qxb4 27.Rxc6 Rf7!) 26...Rb8.

27.Qa5. It's already White who is looking for equality; maybe, for this purpose, 27.Qh7 (bringing the queen to the other side of the board) was better.
27...Kd7! 28.Qc3 Ra8. Both 28...Rb7 and 28...Rb6 seem to be more promising, to meet 29.b4?! by 29...Rfb8.
29.a5 Rfb8 30.b4 Rb5!? 31.Rxb5 cxb5 32.Qc5 (32.Qb3 gives nothing because Black can regroup his forces: 32...Qc6! 33.Nc3 Kd6) 32...Rc8 (32...Qxc5 33.dxc5 can be better for White only) 33.Qxb5+ Ke6! 34.a6

34...Ra8. It's time for a peace treaty. The text move is more simple than 34...Rc2+ 35.Ke1 Qh2 36.Qe8+ Kf6 (which would be also equal). Draw agreed here, due to 35.a7 Rxa7 36.Qe8+ Qe7 37.Qc6+, and so on. 1/2 (Annotated by GM M.Golubev)

The tournament situation hasn't changed after round 4 - Vachier-Lagrave is in the sole lead with 3 points; Nakamura, Karjakin, Andreikin are half-a-point behind. October 25th is the first day-off.
