Moscow GP: Wojtaszek is the first one in the semis
5/22/2019 – Peter Svidler was the first player to be eliminated from the Moscow Grand Prix quarter-finals, after Radoslaw Wojtaszek defeated him with the white pieces on Tuesday. Alexander Grischuk and Wei Yi had difficult positions against Wesley So and Ian Nepomniachtchi, respectively, but they ended up getting a second draw in their match-ups after all.

Komodo 13 thinks like no other chess program. Inspired by AlphaZero, Komodo developers GM Larry Kaufman and Mark Lefler have reinvented their engine from scratch over the last two years. The result speaks for itself: The new Komodo 13 MCTS ("Monte Carlo Tree Search") searches for candidate moves in an incredibly innovative way and finds solutions most engines never see!
Two extra GP points for Radek
Not only is Radoslaw Wojtaszek the first player in the semi-finals, but also he is the first one to gather two extra points in the overall Grand Prix standings after winning both his matches in Moscow without needing tie-breaks. His good results so far have helped him recover the first spot among Polish players on the live ratings list. The player from Elblag has gained twelve rating points in Moscow, after eliminating two players higher-rated than him.

In their return game on Tuesday, the Bundesliga teammates (both play for champions Baden-Baden) pulled out all the stops, with Peter Svidler apparently not in the mood to look for a draw with the black pieces. According to the eight-time Russian champion, the one big mistake that turned the evaluation in White's favour was the check he gave on move 27:
Svidler played 27...♝d4+ and left his bishop on a vulnerable square prior to a series of complex tactical shots in the centre. The computers actually think this check was not the culprit of Black's defeat, however — according to the silicon machines, the error came after 28.♔h2:
Black here opted for 28...♞7f6 instead of the suggested 28...♜b6, which would have left Black with a defensible — albeit not as double-edged — position. After the text, a tactical scramble ensued, in which Peter first decided to sacrifice an exchange and then gave up his queen. Wojtaszek handled the complications effectively and went on to get the pass to the semi-finals after 42 moves.
My best games in the Grünfeld by Alexei Shirov
The Gruenfeld Defense is an active and dynamic reply to 1.d4 which can lead to complex and extremely sharp positions. So it’s no wonder that also Alexei Shirov included this opening into his repertoire. At the candidates’ final against Vladimir Kramnik in Cazorla in 1998, he exclusively – and successfully – trusted the Gruenfeld Indian with Black; the victory over Kramnik gave him the right to play a WCh match versus Kasparov.

In the post-game interview, Svidler showed no regrets about his decision to play a sharp line with Black:
I'm obviously not happy about today. I thought my approach was correct. I mean, I play about every move possible after 3.f3, and I went for the line which is sort of the sharpest and the least clear of all the things I could have done, but I think Radek just played better than I [did] today...and, I mean, I still think that the choice was correct, but I don't have very much experience in these types of structures and eventually this is what decided the game.

So ½:½ Grischuk: Not a disgraceful loss
For a second day in a row, in the final position of the game that faced Wesley So and Alexander Grischuk the American was a pawn to the good, except this time Grischuk was the one on the bad side of the draw — the Russian was in real danger of losing around move 45. The players explored a line of the now widespread Sveshnikov variation of the Sicilian; White got an extra pawn (albeit a doubled one on the e-file); and, after a scare, Black managed to save the draw in 68 moves.

Grischuk was vehement when he referred to his performance in the endgame:
It almost became the most humiliating, embarrassing, disgraceful loss of my career, if I had lost this endgame, and I came close at some point.
Wesley agreed that his opponent could have made an easy draw at some point. The American also confessed that he was happy the draw was not forced immediately, as he wanted to stay in the playing hall to follow Radek Wojtaszek's game...

Make life difficult for the Sicilian! 2.b3 is a thoroughly venomous but still solid kind of "Anti-Sicilian". No matter what setup black chooses, the bishop on b2 will always be unpleasant for him.
Nepomniachtchi ½:½ Wei Yi: "Clearly White was pressing"
A rather disappointed Ian Nepomniachtchi spoke to Eteri Kublashvili after his draw with Wei Yi. Russia's highest-rated player was on top after the opening, but when things started to look increasingly dangerous for Black, Wei Yi sacrificed a pawn and then exchanged into an equal queen endgame to take the mini-match to tie-breaks. The players reached the queen endgame with 3 v 2 pawns on the kingside on move 39, and 'Nepo' kept trying to make something out of the theoretically drawn position during thirty moves, but to no avail.

Unlike in the World Cup, the organizers of the Grand Prix decided that the drawing of colours for the tie-breaks will take place right before the games. When asked about this change, the players generally agreed that it does not make much of a difference, with Nepomniachtchi stating:
We used to know the colour, but in general I think the rules are the same — you play one game with White, one game with Black, so I don't think it really matters.
Perhaps the idea is to avoid the player who gets Black first to prepare an ultra-solid defence for the first game, in order to secure a draw and then play stress-free with White. We will just have to wait and see how the players handle this situation on Wednesday.

Tactic Toolbox Ruy Lopez / Spanish Opening
Starting with Black's alternatives on move 3 and working through until the main lines of the Closed Lopez and the Marshall and Anti-Marshall, the viewer will find his knowledge of the opening developing in tandem with an improvement in his tactical ability.
Dubov ½:½ Nakamura: "Who are you talking to?"
Once again, Daniil Dubov showed good preparation to get the upper hand in the opening against a first-rate player. Hikaru Nakamura, however, kept things under control until signing a 32-move draw. According to Daniil, it was "the exact scenario [he] wanted to have" — risk-free, with the possibility of putting pressure on his opponent. He thought that in order to get something out of his advantageous position, he probably needed to show something extremely concrete, "almost a puzzle". So, given the fact that Hikaru defended well, the result was perceived as fair by both contenders.

A curious exchange took place during the post-game interview, when Eteri Kublshvili asked a question without clearly stating who was supposed to answer:
Eteri Kublashvili: You are going to play on tie-breaks against one of the strongest speed chess players in the world, so what are your expectations from this match?
Daniil Dubov: Who are you talking to? (laughs).
Hikaru Nakamura: Yeah, exactly (smiles). I mean, Daniil won the Rapid [World Championship], let's be fair. So it comes down to a couple of moves probably in either rapid or blitz, and [that's what] makes a difference. If you look at this match against Teimour I had, I was supposed to be this big favourite, but it was only because he made a blunder when he was low on time that I won in this rapid game, so, I mean, anything can happen of course.
