Standings after Round 8

Check out the full replay of live coverage from the day here. The time control for the event is 90 minutes for 40 moves, followed by an additional 30 minutes, with a 30-second increment added from move one.

Vachier-Lagrave - So | ½-½, 50 moves

A sharp piece of preparation put So under pressure in the 5.Re1 Berlin, but he managed to defend precisely and slowly equalize by forcing trades along the e-file. Having a half-point lead in the event, MVL decided not to risk too much, and acquiesced to a draw after all the exchanges. 

After 14.Qf3 Black was under a bit of strain, but So continued with 14...Be6 and 15...Be7, slowly untangling his position.

Caruana - Svidler | ½-½, 42 moves

Caruana essayed an interesting line (6.e5) in the Giuoco Piano, and was able to achieve a small strategic plus, having the better side of a middlegame with opposite colored bishops. However Svidler defended accurately, not letting White get any initiative, and once the queens were exchanged neither side was left with any real winning chances.

Xiong - Mamedyarov | ½-½, 34 moves

The players discussed the topical 3...a6 variation of the Queen’s Gambit Declined, as Mamedyarov gave himself an isolated queen pawn in exchange for long-term piece activity. While the game stayed equal for some time, it was due to open up once the players approached the first time control. As the players entered mutual time-trouble the fireworks started, with Mamedyarov sacrificing an exchange in order to start a direct attack against White’s king. Xiong then missed the best chance to squash Black’s initiative, and instead played a move that was winning in all lines but allowed a fantastic saving resource that Mamedyarov soon found. Black was then able to force a draw by perpetual check.

28...Nd3! saved the game for Mamedyarov, as after 29.Qxd2 Qh2+ 30.Kf2 Qg3+ White is forced to allow a perpetual, since the king cannot step on e2/f1 in view of Bc4, winning the queen.

Dominguez - Shankland | ½-½, 32 moves

This game featured a quiet line of the English Attack (6.Be3) in the Najdorf, with Dominguez looking to outplay Shankland in strategic fashion. But Shankland handled the middlegame just fine, and even managed to reach a slightly better endgame according to the engines. During mutual time-trouble, the players started to repeat moves in a position that appeared equal, but as it turned out both players missed a winning resource for Shankland, overlooking a key tactical detail. Instead, the game was soon drawn by repetition.

After 29.Be6, the players repeated with 29...Nd4 30.Bd5 Nf5 31.Be6 etc., but Black could have won with 29...Rxe4! 30.Bxf5 Rf4, where 31.Rgxg7 is met with R8xf5! (the move that both players missed) and Black is left with an extra piece. If White doesn’t play 31.Rgxg7, then Black has a clear extra pawn and much better position, with excellent winning chances.

Swiercz - Rapport | ½-½, 50 moves

A balanced London middlegame quickly turned sharp when Rapport decided to recapture a piece with gxf6, doubling his pawns on the f-file in exchange for an open g-file. Black’s enterprising play wasn’t really enough to pose serious problems for White, as Swiercz remained better throughout the game, but he wasn’t able to increase his advantage substantially, and the players eventually simplified into a drawn rook endgame. With the draw, So’s GCT victory was secured, as Rapport will no longer be able to pass him in the tournament standings.
