2021 Sinquefield Cup - Day 5 Recap

What started off as a slow day with three draws quickly turned dramatic as Vachier-Lagrave bounced back in today’s round to defeat Swiercz, while Xiong took advantage of a time-trouble blunder by Caruana to upset the World No. 2 in stunning fashion. With the win, Vachier-Lagrave propelled himself back into a tie for first place with 3.5/5, where he shares the lead with both So and Dominguez heading into the rest day tomorrow.

Standings after Round 5

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.

So - Rapport | ½-½, 17 moves

A surprise quick draw in the Berlin ended this game in less than 40 minutes into the round. In the post-game interview afterwards, So admitted he was not feeling well due to “a lack of sleep” from drinking too much coffee in the days prior. The draw also gets Wesley one step closer to clinching first place in the overall GCT standings.

Svidler - Shankland | ½-½, 24 moves

Svidler opted for the rare 6.Bd3 against the Najdorf as the players quickly left charted waters and were on their own in a thematic Sicilian structure. The game stayed even the whole time, with both sides having weaknesses that balanced each other out. After an exchange of knights the players soon repeated moves in an otherwise equal position.

Mamedyarov - Dominguez | ½-½, 38 moves

Using the rare move 7.Re1 in the Classical Queen’s Gambit Accepted, Mamedyarov prepared a sharp pawn sacrifice that gave him long-term compensation in the form of piece activity. However Dominguez defended well, and after a series of exchanges the players found themselves in a dead-equal rook endgame, where they immediately repeated moves.

Vachier-Lagrave - Swiercz | 1-0, 47 moves

Although Swiercz was able to get in some nice preparation in a topical line of the Italian Game, Vachier-Lagrave reacted well and still found a way to pose problems for his opponent. One wrong decision by Black gave MVL the opportunity to seize the initiative, as he found a dynamic way to activate his pieces and secure a large advantage. Further precise technique by MVL allowed him to reach a rook endgame with two pawns up, which he converted smoothly. 

MVL’s 24.Re7! was a powerful move, landing the rook on the all-important seventh rank.

Xiong - Caruana | 1-0, 36 moves

Things looked a bit dangerous for Xiong as he quickly fell worse as White in a Reti Opening, due to Black’s space advantage in the center. However one wrong move by Caruana turned the tables, as Xiong was able to activate his entire position thanks to a strong knight maneuver. In mutual time-trouble it seemed like Caruana had managed to escape into an equal endgame, but a further blunder by Fabiano gave Xiong the opportunity to win a full minor piece, which he immediately spotted. Not seeing a way out, Caruana then flagged in a lost position, earning the 20-year-old Xiong one of the biggest scalps of his career.

After Black’s last move 23...Nc6-d8, Xiong found the strong reply 24.Nb4!, looking to plant the knight on the excellent d5-square.
