US Championships: Sevian beats So, Caruana wins to catch So

by Johannes Fischer
10/22/2026 – Wesley So had gone 48 consecutive games unbeaten at the US Championships, but his run came to an end in the final round of the 2026 edition: playing black, he lost to bottom-of-the-table Samuel Sevian, who had failed to win a single game in the previous ten rounds. As a result, the 2026 US Championship will be decided in a tiebreak, as Fabiano Caruana, who had trailed So by one point going into the round, secured a must-win victory against Awonder Liang. | Photo: Lennart Ootes / Saint Louis Chess Club

Drama in the final round

The long unbeaten run and Wesley So's tournament record favoured him before the game, but another statistic pointed in Sam Sevian's favour: in their previous 14 classical games, Sevian had scored 2 wins and 12 draws against So, and had never lost to him at a long time control. The picture is very different in rapid and blitz, however: in rapid, So leads 5-0 with one draw, and in blitz he leads 5-0 with four draws.

Sevian's strong record in classical games seemed to have given him confidence. In a Nimzo-Indian, he put So under pressure from the outset and, after a strong middlegame, eventually reached a winning rook endgame.

There, however, he lost the thread and spoiled the winning position into a draw. But So failed to take advantage of his chance and, in turn, spoiled the drawn position into a loss.

Sam Sevian in the post-game interview

Caruana benefited from So's defeat. With white against Awonder Liang, he had to win simply to draw level with So. He managed to do so with an attractive game, whose finer points – and much more besides – he explained to Maurice Ashley in an interview after the round.

Before the final round, Caruana had assessed his chances of becoming US champion for a fifth consecutive time and reaching a playoff against So as "essentially zero". Now there will be a playoff: it begins on Thursday, 22 October, at 7 p.m. with two rapid games at a time control of 15+10. If those two rapid games do not produce a winner, two blitz games at 5+2 will follow. If the match is still undecided, blitz games will continue until a winner emerges - there will be no Armageddon game.

Grigoriy Oparin, Caruana's second, could have joined So and Caruana with a win in the final round, but with black against Ray Robson he could do no better than a draw. In a strategically complex Ruy Lopez, both sides played very accurately, and the balance was never seriously disturbed before the draw was agreed on move 37.

Jeffery Xiong scored the third win of the round, defeating Hans Niemann with Black. Niemann never found his rhythm during the tournament and, with a score of 4/11, lost a total of 20 Elo points, dropping below the 2700 mark in the live world rankings.
