Wesley So is running away with the 2026 U.S. Chess Championship. His eighth-round victory over Andy Woodward extended a lead that looks increasingly insurmountable with three rounds remaining in this nine-round event.

The win came in a pawn endgame, the kind of technical battle that separates elite players from the rest. So has now converted three separate endgame victories in this championship alone. That's not luck. That's mastery of a skill that matters when the pieces come off and the board simplifies.

Six points from eight games is a commanding position. So sits alone at the top of the standings, and the gap between first and second has grown enough that catching him requires opponents to beat him directly while hoping for help from other results. With three rounds left, the math heavily favors So's first U.S. Championship title since 2017.

This is the tournament So needed. The 33-year-old has spent the last year rebuilding after a period outside the world's absolute elite circle. His 2825 rating still ranks him among the planet's best, but there's distance between top-ten and championship-contending form. Winning the U.S. title would answer questions about whether So remains a serious contender for the world's highest prizes.

Woodward fought in a pawn endgame that could have gone either way at critical moments. The loss drops the young American's title hopes but doesn't eliminate them entirely. Third place or better is still mathematically possible, though the path requires near-perfect chess from here.

The U.S. Championship is entering its decisive phase. So's lead means other players must treat every remaining game as must-win. That creates opportunities for upsets but also favors the player with the steadiest nerves. So has demonstrated that steadiness throughout this event.

The championship will determine its challengers in the final three rounds. If So holds serve, he returns to the American chess throne at a moment when the country needs strong representation in international competitions. If he falters, the title race opens up immediately. Either way, the next three rounds will be worth watching carefully.
