Sinquefield Cup: Theoretical lines

Four theory-heavy draws were seen in round 7 of the Sinquefield Cup. Wesley So did not play on Friday — he was paired up against Magnus Carlsen — but kept the sole lead nonetheless. With two rounds to go, Alireza Firouzja and Ian Nepomniachtchi are the leader’s closest chasers. So is set to face Firouzja with black on Saturday. | Photo: Grand Chess Tour / Bryan Adams
