It's Ding's to Win

Ding Liren is in the driver’s seat as the final round of the 2019 Sinquefield Cup nears. His draw against Levon Aronian, coupled with Ian Nepomniachtchi’s loss to Maxime Vachier-Lagrave, gives him a slender half-point lead over four players heading into Wednesday's 11th and final round. A win will give Ding his first Sinquefield Cup title, while a draw opens the door to a playoff on Thursday.

Nepomniachtchi has been the tournament’s most dangerous player, with four decisive games (three wins, one loss) as of Tuesday's 10th round. His fluctuations in form continued here against Vachier-Lagrave, when Nepo inexplicably played 21.Nd7? instead of 21.Nc6, which would lead to a quick draw. MVL headed to the confessional to admit as much…

…while Nepomniatchtchi took to Twitter to describe his bewilderment at his blunder.

Meanwhile, Ding trotted out the Two Knight’s Defense against Aronian, and after doubling Aronian’s d-pawns in the trendy 8.Bd3 line, Ding always had enough compensation to keep the draw in hand.

Magnus Carlsen broke his duck with the second win of the round, defeating Wesley So in a game where Carlsen simply seemed to understand the nuances of the middlegame better.

The win improbably pushed Carlsen into shared second place, along with Nepomniachtchi, Viswanathan Anand, and Sergey Karjakin. Anand and Karjakin drew in another game that Anand may feel that he should have won.

Anand has found ways to get great advantages against his opponents here in Saint Louis, but in multiple games he has been unable to convert those advantages into full points. Garry Kasparov, who is preparing for his own return to the board in the Champions 960 event that follows the Sinquefield Cup, dubbed Anand the “Robin Hood of Chess” in a Tweet.

The remaining two games were drawn. Hikaru Nakamura and Anish Giri found an early path to a repetition, while Shakhriyar Mamedyarov and Fabiano Caruana also played to a draw. Final Round Pairings
