A remarkable penultimate round at the Sinquefield Cup saw Ian Nepomniachtchi, Fabiano Caruana and Alireza Firouzja scoring full points to climb to shared first place with 4½ points each. For Caruana, however, it is all but impossible to win the event, as he will not play in Sunday’s final round, when he was supposed to face Magnus Carlsen. In the one draw of the day, Shakhriyar Mamedyarov managed to escape with a half point from an inferior position against Leinier Dominguez. | Photo: Grand Chess Tour / Lennart Ootes
