The 2026 American Cup opened Monday at the Saint Louis Chess Club, bringing together the best players in North America for a knockout event running through March 12. Wesley So defends his title against a men's bracket that includes Fabiano Caruana, Hikaru Nakamura, and Sam Shankland. Alice Lee, Jennifer Yu, and Irina Krush headline the women's side.
The format is straight knockout: four rapid games per match with Armageddon tiebreaks if needed. It rewards consistent execution under pressure over multiple days rather than individual game brilliance.
Saint Louis has become the center of American chess over the past decade. The facility is world-class, the live broadcast draws national viewers, and the prize money is competitive with European elite events.
So enters as the defending champion and a player who has looked sharp all winter. Caruana and Nakamura are both chasing him. Nakamura has finished second here twice and is overdue for a title. The women's bracket is harder to predict. Lee is seeded first but Yu has won this format before and plays well under pressure. First round games begin at 10:00 AM Central Time on Chess.com.
