b7-b6! and Black wins

Baadur Jobava is the only one who has managed to score a victory in the 8th round of the FIDE Grand Prix tournament taking place in Tashkent. As Black, he has defeated Boris Gelfand who is having an unsuccessful competition with already four defeats. The creative GM from Georgia whose rating is next to last is now tied (quite unexpectedly) for the 1st place with Hikaru Nakamura and Dmitry Andreikin.

Jobava's win over Gelfand is literally and figuratively an example of how the "side-strategy" can triumph over the central one, starting from the very beginning. However, note that something went wrong in Gelfand's central strategy at some point, as the transfer of the white knight to h3 was quite counterproductive. This had been in fact the main reason behind White's loss, as later on it was already Jobava who was pressing hard in the center.

GELFAND - JOBAVA
1.d4 e6 2.c4 b6 3.e4 Bb7 4.Bd3 Bb4+ 5.Bd2 (Wesley So had chosen the quite rare move 5.Kf1!? against Jobava this summer) 5...Bxd2+ 6.Nxd2 d6 7.f4!?

7...Nd7 (not necessarily the best move, but definitely one of the most obvious) 8.Qg4!? (simple 8.Ngf3 might be preferrable, for example: 8...Ne7 9.0–0 0–0 10.Qe1 - White is slightly better here, according to Jobava) 8...Ngf6 9.Qxg7 Rg8 10.Qh6 Rxg2 11.Ngf3 (the alternative is 11.Ne2!?) 11...Qe7 12.Qh3 Rg7 13.0–0–0 (in case of 13.e5 the Georgian GM was planning 13...dxe5 14.fxe5 Ng4 15.Rg1 f5)

13...Ng4! (objectively speaking, 13...0–0–0 isn't worse, but White's play would have been much clearer: 14.Rhg1 Rdg8 15.Rg5, and so on) 14.Qg3?! It seems that both opponents were underestimating 14.Qg2!, with the intention of bringing the queen back to e2 if needed, as the g4-knight is pinned for the moment. White is slightly better here.
14...Ndf6! Now Black's dynamic resources are serious - his position isn't already worse at the very least.
The threat is ...Nh5.

15.Ng5?! (instead of this dubious knight transfer, a pawn sacrifice was deserving attention: 15.Rdg1!? Nh5 16.Qe1 Nxf4 17.Bc2) 15...h6 16.Nh3. 16.h3 hxg5 17.hxg4 gxf4 18.Qxf4 Rxg4 19.Qf3 0–0–0 is also hardly sufficient for equality, but maybe complicating the matters by 16.h4!? was better; Jobava was thinking of meeting it by 16...0–0–0.
16...0–0–0. Black is definitely better now, his chances growing even more after Gelfand's next move.

17.Rde1?! (17.Qe1!? - Jobava) 17...Nh5 18.Qf3 Qh4!? 19.Re2 (if 19.Qf1 then 19...Nxf4! 20.Nxf4 Nf2! - Jobava) 19...Kb8!? "Of course, I had to play 19...f5", Jobava pointed out - although the line 20.d5 Nxf4?! 21.Nxf4 Ne5 mentioned by him is in fact quite unclear because of 22.Ng2!, etc.
20.Bc2 (20.Qf1 was mentioned by both opponents at the press conference; probably the most unpleasant reaction is 20...Qf6!?) 20...f5 21.Qf1 Nhf6! 22.Nf3 Qh5

White has failed to solve the problem of his passive and vulnerable h3-knight. His position is about to collapse.
23.exf5 exf5 24.d5 Re8 (24...Ba6! was also strong, attacking the c4-pawn and preparing ...Nxd5) 25.Rxe8+ Qxe8 26.Qd3 Re7! 27.Rf1 (27.Qd4 is a bit more persistent) 27...Ne3 28.Rf2 Ba6 29.Bb3 Nexd5 30.Qxf5

30...Bxc4! The final blow. White resigned due to 31.Bxc4 Re1+ 32.Nxe1 Qxe1+ 33.Kc2 Ne3+. 0–1 (Annotated by GM M. Golubev)

The most interesting draw of the round was probably Karjakin - Mamedyarov. Both were creative and precise in the double-edged fight, so the result is logical.

MAMEDYAROV - KARJAKIN

17.0–0! a5! 18.Nxe5! axb4 19.Nxg6 fxg6 20.e5 (Black is probably in order in case of 20.axb4 Rxa1 21.Qxa1 Nxd5!) 20...Nfd7 21.Bxe7. Karjakin: "Since approximately this moment, I knew what I was doing - it seems I had been analysing 21.Bg3 bxc3 22.Qd3, and here it's very important for Black to play 22...cxd5!" Regarding that the theory has ended already with the Black's 9th move, Karjakin's opening preparation is really impressive.
21...Qxe7 22.Bxg6 (22.e6!? bxc3 23.Bxg6 is probably also roughly equal).

Karjakin could force a draw right now by 22...Qxe5 23.Bxe8 (23.Ne4?! Rf8 and Black is better - Mamedyarov) 23...Qg3+, but he decided to keep playing for a win (regarding his time advantage at the moment) by 22...bxc3. However, it was the Russian GM who had to be more accurate later on. Both players managed to avoid mistakes in the further play, and the peace treaty was signed on move 41.

Kasimdzhanov solved his opening problems vs Caruana by a logical novelty.

CARUANA - KASIMDZHANOV

15...b5! (15...Nxe5 had been tried several times before). The game was mostly drawish till the end when Caruana messed it up a bit, while Kasimdzhanov failed to extract anything real out of that.

The other games were hardly interesting. Andreikin - Vachier-Largave was a short draw by repetition in the Grunfeld Defence.

The encounters Giri - Jakovenko and Nakamura - Radjabov were too dry to annotate them in details.

Tomorrow (October 30th) is the second and last day-off in the tournament. Round 9 will be held on Friday.
