"This title is so hard to get"

The first exciting moment came as early as move 11 of the first game: in a variation of the Nimzo-Indian, Wesley So surprised with the novelty 11...Nb6!?, a move that at first glance looked like a mistake and invited White to win a piece. But Fabiano Caruana apparently considered the gift poisoned and opted for a quiet continuation.height="1"

So continued to play energetically and strongly, however, and gradually increased his advantage - on move 27 he won a pawn, and on move 34 he missed a forced win. But then the game turned around, and Caruana generated more and more counterplay in a tactically complicated position in which both sides had only seconds left on the clock. After 72 moves, the game ended drawn by repetition.

The opening in the second game was also surprising. This time around, it was Caruana who came up with the surprise. Playing black, he chose a dubious, speculative gambit line. So responded cautiously and returned the pawn, but in doing so, secured a clear advantage.

Then, once again, the tension of the playoff and the long tournament began to show: Caruana miscalculated and blundered a piece. A few moves later he resigned, and Wesley So was declared the 2026 US chess champion!

In his interview with Maurice Ashley after the playoff, Caruana tried to explain why he had chosen the double-edged opening. "I knew this line existed. I don't know why I chose it. I mean, it's probably a bit too risky".

He was also puzzled by his tactical oversight at the critical moment of the game: "I thought that his queen had to go to a4. I didn't really spend any time calculating, I just went for it, which was obviously insane".

More generally, Caruana was frustrated with his rapid-chess form. "I have lost about 110 Elo points in a year. But I don't know what's been going on. I haven't been able to find my form".

Wesley So, who despite all the excitement on the board appeared calm, focused and composed throughout the playoff, revealed in his interview after the round how much the defeat against Sevian had affected him. "I think I only slept for two or three hours, and I was not in the mood to play today at all".

But he praised his opponent: "Sam had a very tough tournament. I was shocked with the way he played - it was a very good game. But I also played very badly".

Despite winning the title, So was not satisfied with his play overall: "I don't think I deserved to win this year, but I'll take it of course." He added that both players had made many mistakes in the playoff, noting that both contenders were very tired.

For all his self-criticism, So was ultimately satisfied: "I am very happy to have won my fourth US Championship. This title is very difficult to win, especially now that so many strong grandmasters are taking part".
