Here Wesley has left Swiercz with two targets, the d-pawn and g-pawn.

Wesley Secures Big Win 🎯

A big and important win for Wesley So in a long, 72 move game! The opening was an offbeat Nimzo-Larsen Attack, with Swiercz playing ambitiously from the start, launching a kingside pawn storm. Wesley, calm and solid, navigated the complications, and after a queen exchange, the game entered a long, maneuver-heavy positional endgame.

Swiercz found himself in critical time pressure, and Wesley gradually built a small but persistent advantage, applying the principle of two weaknesses to create multiple targets. The endgame saw swings, with Swiercz having moments to equalize, but Wesley’s resilience and precise play eventually converted the advantage into a full point.

With Caruana’s game still ongoing, the leaderboard is in flux, but this result certainly shakes up the title race. Stay tuned tomorrow for the final round, where the U.S. Championship will be decided!

🎙️ Welcome to Round 10 of the 2025 U.S. Chess Championship! 🇺🇸

Welcome to Round 10 and our live commentary! With just two rounds remaining, every move now carries enormous weight in the race for the U.S. Championship title. After Round 9, Fabiano Caruana leads the field with 6.5/9, followed closely by Wesley So on 6/9, and Levon Aronian on 5.5/9.

Today, all eyes are on Wesley So’s game against Dariusz Swiercz. Wesley, still unbeaten in this tournament, comes from a solid draw against Sevian and needs a win to catch up with Caruana before the final round. Swiercz, meanwhile, has had a challenging event so far, sitting at 3.5/9, and will be looking to bounce back with a strong performance.

Can Wesley score with the black pieces and set up a thrilling finale tomorrow? Let’s find out!
