Wesley So maintained his unbeaten record and claimed outright first place in the 2026 U.S. Chess Championship after round seven. His win over Ray Robson proved decisive in a tightly contested battle where So recovered from a disadvantageous endgame position. The victory lifted So to five points, one ahead of Fabiano Caruana and Andy Woodward, who each drew their games to remain at 4.5 points.

Awonder Liang's tournament took a significant turn when he fell to Grigoriy Oparin in just 27 moves. The loss came after Liang made a series of uncharacteristic tactical errors, including a questionable queen trade that led to an inferior endgame. Observers attributed these mistakes to fatigue, a pattern emerging as the championship entered its decisive stages with four rounds remaining.

The So-Robson game showcased the tournament's demanding pace. Robson had achieved a winning advantage in the endgame and declined a draw by repetition, choosing to continue playing with 30.f4. However, time pressure and subsequent miscalculations in the bishop endgame allowed So to turn the tables and secure victory.

In the women's championship, WIM Rachael Li and IM Alice Lee emerged as joint leaders on 5.5 points after decisive victories. Li demonstrated composure and tactical clarity with an unconventional opening and strong middlegame execution. Lee similarly triumphed despite early pressure in her game, maintaining a position just half a point behind.
