One of America’s heavyweights hit the proverbial U.S. chess championship canvas, as seeded GM Fabiano Caruana was knocked down by generic tournament GM Daniel Naroditsky on Monday afternoon.

The world number 2 has looked weak in the knees since the national title fight started last week at the Saint Louis Chess Club, seeing him stumble unusually on the first few laps and sweat through several lower positions just to save draws. But Naroditsky came to St. Louis to fight, producing rulings in every first-half game of the tournament, and the left-side general manager connected in a Ruy Lopez in the fifth round.

Caruana as White had made a solid push to the center, but took an awkward step back with 29. Nc3, allowing Naroditsky to pounce on the initiative with a queen trade at 30.… Qb3. The trade put the top seed in America under considerable time pressure, prompting a puff to 36. Rc1? and give Black a material advantage. Naroditsky’s conversion to world number 2 – described as an “incredible euphoric feeling” – was quite an achievement, here under the microscope of Chess Life editor John Hartmann.

The loss drops Caruana to fifth place at 2.5 / 5, a point behind leaders GM Ray Robson and GM Alex Lenderman, who joined first place at plus-2 with his second straight win – a six-hour conversion. and 140 shots. against general manager Samuel Sevian on Monday. Third place is shared by the other two American heavyweights, 2700 listed GMs Wesley So and Leinier Dominguez, who are expected to face each other in a important sixth round Tuesday.
