The Moscow Grand Prix, which is being held at the Central Chess Players’ House, is the first in a series of four tournaments to select two players for next year’s Candidates tournament. The winner of that tournament will become the challenger for the 2020 World Championship match to be held in November.
There are 21 players in the Grand Prix, with each playing three of the four tournaments. There are 16 players in each tournament.
The prize fund for each competition is 130,000 euros with an additional 280,000 euros allocated among the top 10 finishers in the series, for a total of 800,000 euros.
The principal sponsors of the series are PhosAgro, a giant Russian fertilizer company, and Kaspersky Lab, a worldwide leader in data security. The series is being organized and broadcast by Worldchess on its Web site under the auspices of the World Chess Federation, which is better known as FIDE, the game’s governing body.
For the first time, the Grand Prix is using a knockout format. Each player faces another one in two classic, or slow games over two days, going to a series of faster tie-breaker games on a third day if the match is tied.
That was necessary for three of the quarterfinal matches after the regulation games were drawn.
Nakaumura, who faced Daniil Dubov of Russia, took control of his tie-breaker by winning the first game, even though he had Black. The opening was a Classical English, with Dubov essaying 8 b3, which is a bit unusual. Nakamura had little trouble equalizing and even managed to obtain the bishop pair. The game seemed most likely to end in a draw until Dubov inadvisedly grabbed Nakamura’s pawn on d5, trapping his rook. Nakamura was able to win the rook for a bishop and then gradually outplayed Dubov in a long endgame.
In the second game, Dubov faced a must-win situation, but it was Nakamura who established an edge out of the opening. He eventually won an exchange and then forced an endgame where he was clearly better. Though Nakamura could probably have won if he wanted to, he was content to force a draw by repeating the position as that clinched the match.
Nepomniachtchi was paired against Wei Yi of China. Game 1 was exciting as Nepomniachtchi, who had Black, chose to defend the Poison Pawn Variation, which has been heavily analyzed and is very complex. After a forcing sequence of moves, the players simplified to an ending in which Wei was a little bit better. Nepomniachtchi pressed too hard and eventually lost his one piece for several pawns, but they were disconnected and seemingly easy targets. The one factor weighing in Nepomniachtchi’s favor was that he had more time on his clock. Wei slowly increased his advantage until Move 44, when he erred, costing him his edge. Nepomniachtchi was able to win Wei’s bishop for a passed pawn, after which the players agreed to a draw.
In Game 2, Wei chose an inferior version of the Caro-Kann Defense. By Move 20, he was already under pressure when he blundered with 20 … f6, overlooking Nepomniachtchi’s clever reply – 21 h4! Suddenly, Wei could not avoid the loss of a significant amount of material. He chose to give up his queen for a rook and a knight, but Black had too many weak pawns and Nepomniachtchi was able to force resignation after 45 moves.
In the third playoff, Grischuk had Black in Game 1 against Wesley So of the United States. The opening was the Sveshnikov or Pelikan Variation in the Sicilian Defense. Grischuk built up his forces on the kingside while So concentrated on the queenside, attacking Grischuk’s weak pawns. So managed to win those pawns, but only by allowing Grischuk’s attack to become very menacing. Just when it seemed that Grischuk was ready to break through, he allowed a perpetual attack on his queen, ending the game as a draw. If, instead of 27 … Qc5 he had played 27 … Qe7, the computer engines evaluated the position as very much in Black’s favor.
In Game 2, Grischuk obtained a clear edge out of the opening as he was able to break apart So’s pawns. So defended admirably for quite a while, but, eventually, the pawn weaknesses were simply too much. On his 42nd move, Grischuk won a pawn and eventually achieved a winning rook-and-pawn ending after a few inaccuracies by So.
In an interview afterward, Grischuk was not too happy with his play in either game, saying, “My technique was 50 percent of Magnus [Carlsen], which was enough.” (The entire interview can be seen at World Chess Youtube channel)
The semifinals begin at 3 PM local time on Thursday. The broadcast can be viewed free and live at worldchess.com.
