Moscow GP: Grischuk takes down Nakamura

A strange choice with Black

In his sixth classical game of the event, Hikaru Nakamura went past the time control for the first time in the tournament — of course, he did play more than forty moves in the rapid tie-breaks. In his closing balance, the American was left with three points in the GP overall standings, with his strength in quicker time controls a big asset for the future in this format, as was proven in his match-ups against Teimour Radjabov and Daniil Dubov. Nakamura will also play in Jurmala/Riga (second leg, July) and Hamburg (third leg, November).

In his second game against Grischuk, Hikaru played a line he had used repeatedly in the recent past. Alexander declared afterwards that, at the same time, he "expected and [did] not expect [this variation]", as he thinks it is a very difficult line for Black. The ensuing position is highly complicated, with Grischuk explaining that the computers tend to change their assessments when they evaluate this sort of setups. The Russian was within his home preparation until move 20.

Between moves 21 and 26, the players spent 69 minutes (Grischuk) and 78 minutes (Nakamura), proving how tactically complicated the position actually was. By then, White was already in the driver's seat, although only a precise handling of the position would turn his edge into something tangible. According to Hikaru, his problems began after a strategical mistake on move 25:

Master Class Vol.7: Garry Kasparov

On this DVD a team of experts gets to the bottom of Kasparov's play. In over 8 hours of video running time the authors Rogozenko, Marin, Reeh and Müller cast light on four important aspects of Kasparov's play: opening, strategy, tactics and endgame.

Naka explained that he played 25...♚h8 because he did not foresee Grischuk's 26.♗d3. Hikaru declared: "I think it's still okay, but everything is going the wrong way — if anyone is pressing it's White". In fact, Black's position started to collapse and, shortly before the time control, White found a forcing continuation that left him completely winning:

Hikaru's 37...♞c4 allowed 38.♘xd8 ♞e3+ 39.♔f2 ♞xc2 40.♘xf7+ ♚g8 41.♘xe5 and White is winning.

Power Play 24: A repertoire for black against the Catalan

On this DVD Grandmaster Daniel King offers you a repertoire for Black against the Catalan, based around maintaining the rock of a pawn on d5. Keeping central control ultimately gives Black good chances to launch an attack against the enemy king.

Grischuk is the first finalist in Moscow. So far, he knocked out Sergey Karjakin and Nakamura in the classical phase, while he defeated Wesley So on tie-breaks. His performance in classical chess has netted him 8.4 rating points, which leaves him tied with Nepomniachtchi in the live ratings list — thus, they share Russia's top spot in the world ranking.

He will now have two rest days before the final match-up. Will he follow closely the tie-breaks between Wojtaszek and Nepomniachtchi in order to prepare beforehand? Sasha responded:

I would watch it even if I didn't play this tournament. I just like watching such events.

Post-game interview with Grischuk and Nakamura

Wojtaszek ½:½ Nepomniachtchi: "Not the most principled line"

After getting a big edge on the clock and deciding to avoid unnecessary risks in game one, Ian Nepomniachtchi quickly equalized with Black and ended up getting a comfortable 22-move draw against Radek Wojtaszek on Thursday. White played a sideline that transposed into a King's Indian structure which is not very dangerous for Black and, after some simplifications, the players decided it was in their best interest to decide the match on tie-breaks.

It remains to be seen whether the fact that Wojtaszek overcame rounds one and two without going through rapid tie-breaks will work in his favour or not. Nepomniachtchi is, after all, a particularly quick player, although he recently performed below expectations in Abidjan — he finished in shared last place in the Rapid, after losing five games and winning one. He might, therefore, try to transfer the battle to quicker time controls by using a solid strategy in the 25+10 games...

Anti-Bajonete-Attack in the King's Indian

The Mar del Plata Variation in the King's Indian could be faced with an uncomfortable Bayonette Attack. Marin shows how to face that.

Radek repeated a line of reasoning we have heard once and again during this tournament:

It's better to make a draw instead of just start drifting and having some problems after that.

Does Nepo have a special strategy for the tie-breaks? His response was as clear as day:

Eteri Kublashvili: What do you think is the most important ingredient for success in the play-off match at your level?

Ian Nepomniachtchi: No idea (smiles). Seriously, no idea.
