In Saint Louis, the sixth round of the Sinquefield Cup produced another full set of draws, though the results concealed the drama on several boards. Maxime Vachier-Lagrave once more failed to convert a winning position, this time against Nodirbek Abdusattorov, while Alireza Firouzja also missed chances to defeat world champion Gukesh Dommaraju, who defended tenaciously. | Photo: Lennart Ootes
