The status quo hasn't been broken: Andreikin stays in the sole lead

All the games have been drawn in the penultimate round of the 2nd FIDE Grand Prix stage in Tashkent; however, it could hardly have been expected during of the round as the struggle was very real. 2 or 3 games could easily have ended in favour of one of the sides.

The leader Dmitry Andreikin was defending a slightly worse position vs Boris Gelfand for a long time, having chosen the Chebanenko system of the Slav Defence where Gelfand had defeated Vishwanathan Anand as White during the 2012 World Championship match. The Russian GM has managed to hold.

Retrospectively, one can suppose that Gelfand could pose more problems had he not opened up the center so quickly: 21.f3 f5 22.e4.

Mamedyarov and Vachier-Lagrave had swapped the queens off the board already on move 9 which resulted in a complicated endgame, slightly better for White. The further stage of the game was like a swing: the Frenchman would almost equalise but then make an inaccuracy again, offering new chances to his opponent, and so on... Mamedyarov even got 2 extra pawns at the end, but they were by no means easy to convert into the victory because of the Black's pair of bishops (vs a bishop and a knight) in the open position, as well as the slightness of the material.

The most creative participant of the Tashkent tournament, Baadur Jobava, experienced hard times vs Anish Giri after he had messed up in the middlegame, having missed the unpleasant 31.c5! Later on, White's chances for the win were huge, but the young Dutchman began to make inaccuracies in turn and allowed Black to extricate himself from the extremely difficult pawn-down endgame.

GIRI - JOBAVA

Instead of 51.f3?! (a small deviation from the correct course but not the last one) White could play 51.Rd4! with the basic idea of Rg4+, f4, Be5; if 51...Bb2 then 52.Rd2! and 53.Ra2. However, the crucial turn in the wrong direction was 60.g5?!. Thus, Giri has missed the victory which had seemed almost certain; at the same time, one cannot rule out very resourceful defence by Jobava.

The Caruana - Karjakin encounter saw a line of the Grunfeld Defence (transposed from the Reti Opening) which had taken place in the quite famous Nakamura - Kramnik game (Olympiad 2012; the American won). The middlegame had been balanced, with White's advance at the king side equated by Black's positional achievements at the other one, until the Elo favourite started to make mistakes: 27.Re1? followed by 32.Rec1? five moves later (the latter is in fact hard to explain). Eventually, it was the white king which ended up in a trouble, but the Russian has missed his chances.

CARUANA - KARJAKIN

Sergey had already complicated his task by 32...exf5 (32...Rh8!) but then managed to rehabilitate himself by a series of extremely precise moves. In the diagram position, he had to find yet another unobvious one, 38...Ba6!! (the b7-square is more important than the pawn). After 39.Qxd5 a4 Black can combine threats on both sides and should eventually break through the opponent's defence; White's extra pawn doesn't really matter. Instead, Karjakin went for 38...a4? and the repetition: 39.Rb7 f6 (39...Qe1+ 40.Bf1 Rg6+ 41.Kh2, and Black has no time for capturing the bishop) 40.Rb8+ Kf7 41.Rb7+ Kf8 1/2.

Jakovenko has held the Queen's Gambit Declined as Black against Hikaru Nakamura without too much of a trouble. Kasimdzhanov - Radjabov were fighting in the Hedgehog-like opening scheme resulted from the Taimanov variation of the Sicilian; again, White wasn't able to pose serious problems.

Thus, the standings after 10 rounds are: 1. Andreikin - 6.5 points; 2-3. Nakamura, Mamedyarov - 6; 4-5. Vachier-Lagrave, Jobava - 5.5.

The final round will start earlier than usual (tomorrow at 6:00 GMT). The pairings for the last round are: Andreikin - Giri, Vachier-Lagrave - Nakamura, Jobava - Mamedyarov, Jakovenko - Caruana, Karjakin - Kasimdzhanov, Radjabov - Gelfand.
