A clear leader emerged today as Vachier-Lagrave broke through the gridlock with a crucial win over Xiong, giving him a half-point lead over So and Dominguez who could only draw their games. Meanwhile, Caruana scored an important victory as Black over Mamedyarov, propelling him into a tie for second place as well. With two rounds left to play, everything is still on the line both in terms of the tournament and the overall GCT standings.
Standings after Round 7
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.
Rapport - Dominguez | ½-½, 45 moves
A sharp counter-gambit (5...e5) in the Queen’s Gambit Accepted gave Dominguez the initiative from the opening, as he gained a lead in development while chasing down Rapport’s queen. Though Rapport defended well, finding all the right moves needed to go into a drawish endgame. More simplifications occurred before the players agreed to a draw in a dead-equal bishops of opposite color endgame.

Vachier-Lagrave - Xiong | 1-0, 29 moves
It only took one mistake (18...hxg4) for Xiong to land in massive trouble in the Berlin Endgame, as he erroneously opened up the h-file for White’s connected rooks. MVL wasted no time in seizing the initiative, as he advanced his pawn all the way to f6 before taking over the h-file and soon crashing through with his pieces. Facing huge material losses with his king stuck on e8, Xiong resigned.
MVL’s 20.Rh1! led to catastrophe for Black, as the resulting invasion along the h-file simply couldn’t be prevented.

Svidler - Swiercz | 1-0, 35 moves
Despite solid preparation as Black in the Ruy Lopez, Swiercz quickly got himself in trouble after an ill-advised pawn grab (18...Qxc3) left his position under severe tactical strain. Svidler rapidly activated his pieces, and managed to stir up threats that would soon win him a full piece. With no compensation for the lost material, Swiercz was forced to throw in the towel.
21.Ba4! was the killing shot in Svidler - Swiercz, leading to huge material losses after the follow-up of Ra3.

So - Shankland | ½-½, 34 moves
It wasn’t the best day for So, who outplayed Shankland in a topical line of the English but quickly let his advantage dissipate as he failed to find the optimal way to capitalize on his edge. Shankland took the opportunity to equalize with a nice pawn break (23...f6), successfully neutralizing White’s space advantage. From there, So forced a repetition of moves, and the game was drawn.

Mamedyarov - Caruana | 0-1, 38 moves
The final game of the day to finish was exciting throughout, with both players opting for a sharp struggle in the 4.f3 Nimzo. It was Caruana who held the initiative early on, as he had the safer king and more active pieces, but Mamedyarov held the better long-term chances, thanks to his two bishops and somewhat healthier structure. After defending quite well, however, Mamedyarov ended up blundering in mutual time-trouble, losing the exchange without any significant compensation for it. Caruana grabbed the extra material and was able to consolidate, forcing resignation before the end of the first time control.
26.Qe2 was the start of White’s problems, as after Caruana’s reply 26...Nf6! Mamedyarov immediately erred with 27.Qd1, losing the exchange after 27...Bxd3 28.gxf6 Bxf1 -+
