Grischuk has defeated Inarkiev and seized the lead

The TASHIR supertournament in memory of the 9th World Champion Tigran Petrosian has seen its start in Moscow. The only decisive game of round 1 was the one between Alexander Grischuk vs Ernesto Inarkiev: Alexander has outplayed his opponent as White in a very convincing manner. As the member of the Russian national team pointed out, he "had got a solid advantage right in the opening". The further play was more like a demonstration of White's realization technique.

GRISCHUK - INARKIEV
Reti Opening
1.Nf3 Nf6 2.c4 e6 3.g3 d5 4.Bg2 dxc4?! It might be a bit premature to make conclusions on move 4, but 4...Be7 (keeping the long diagonal closed) looks more reliable. If 5.0-0 0-0 6.d4 (6.b3 c5) then 5...dxc4 is already good, as the game transposes to well-known positions of the Catalan Opening. Another option is 4...d4!? (Karjakin - Anand, Dubai 2014).
5.0–0 Be7 6.Na3 c5 7.Nxc4 Nc6 8.b3! 0–0 9.Bb2 Bd7?! (the line chosen by Black wouldn't promise him simple equality anyway, but maybe 9...Qc7 had to be preferred) 10.d4! Rc8 (or 10...cxd4 11.Nxd4 Rc8 12.Nb5! - Grischuk; 10...Qc7 11.dxc5 Bxc5 12.Nfe5!? - Inarkiev)

11.dxc5! In case 11.Rc1 Black can neutralize the dangerous Catalan bishop by 11...cxd4 12.Nxd4 Nxd4 13.Qxd4 Bc6! (Tal - A. Sokolov, Reykjavik 1998).
11...Bxc5 12.Nd6 Rc7 13.Rc1 b6 14.Ng5 Qe7 (if 14...e5 then 15.b4! is interesting - Grischuk) 15.Nge4 Nxe4 16.Nxe4 Rd8 (16...Bb4?! 17.Be5!) 17.Nxc5 bxc5

As a result of the opening, Black's position is "very sad", according to Grischuk. The isolated c5-pawn is very difficult to hold in absence of the dark-squared bishop. Alexander's comment on the further play was brief: "Of course, I played like an old man trying to exchange as many pieces as possible, but it seems to me that Black's position was extremely difficult all the time".

Even though the game looks really one-sided, we would warn the readers from making premature conclusions and signing Inarkiev up for the outsiders, because Ernesto is known for his ability to mobilize himself after a poor start or at any other moment when necessary.

Vladimir Kramnik decided "to stick to a reliable style in the first round", according to the ex-World Champion himself. Having the black pieces vs Ding Liren, he opted for a well-known line of the QGD where queens go off the board quickly, and Black gets a pair of bishops in compensation for his forever spoiled pawn structure. According to Kramnik, he hadn't been able to find anything dangerous for White in this line, so he decided to try it over the board.

DING LIREN - KRAMNIK

13.0-0-0 was characterized by Vladimir as slightly straightforward: "Now I have enough time to bring my knight to d6, which is the key transfer here". According to him, after 17...f5 White had "nothing but symbolic advantage"; neither of the sides could change the statics of the position without taking strategic risks. After some maneuvering, the draw agreement was reasonable.

At least two interesting moments from Aronian - Gelfand deserve our attention.

ARONIAN - GELFAND

The Israeli GM, who is playing his 3rd tournament in a row, hasn't made up his mind for a typical bishop sacrifice: 13...Bxh2+!? 14.Kxh2 Ng4+. However, its consequences could not be predicted easily: 15.Kg3! Qg5 (perhaps 15...bxc6!? is better, with the idea of 16.Qd4 Qg5 17.Qxg7+ Qxg7 18.Bxg7 Kxg7 19.Bxc6 Nxe3!) 16.f4 (the next moves are almost forced up to Black's move 20) 16...Qg6 17.Bd3 f5 18.Ne5 Nxe5+ 19.Kf2 Ng4+ 20.Ke1. Now if 20...Nxe3 then 21.Qd2 Qxg2 22.Rg1 Qxg1+ 23.Nxg1 Nc4+ 24.Be5!? Nxd2 25.Kxd2.

And White is clearly better despite his material deficit.

Gelfand chose the modest 13...bxc6 and got a decent position which later transformed, by Aronian's efforts, to a rook endgame favourable for White. The opponents agreed that it had been drawish initially, but Gelfand started to play inaccurately when it came closer to the first time control.

The Black rook is quite awkward; according to Aronian, 41.h3! would have given him good winning chances instead of his 41.h4?! After 41.h3, if Black plays as in the game (41...f6+ 42.Kd5 Kf7 43.e5 Ke7) then White has 44.g4 hxg4 45.hxg4 Ra4 46.g5!.

Alexander Morozevich went for a side line of the Sicilian against Peter Leko - 1.e4 c5 2.Nf3 a6. The Hungarian's 3.c3 led after 3...d5 to a version of the Alapin system slightly improved for White. Morozevich hasn't been able to reach complete equality up to the end of the game; however, Leko decided to share a point because of his lack of time. As Leko explained later, he was too short of time to find a reasonable plan.
