Saint Louis Chess Club

The Saint Louis Chess Club (previously named the Chess Club and Scholastic Center of Saint Louis) is a chess club located in the Central West End in St. Louis, Missouri, United States. Opened on July 17, 2008, it contained a tournament hall and a basement broadcast studio before its expansion began. On September 19, 2022, all Club operations temporarily moved to the adjacent space that housed the original incarnation of the chess-themed Kingside Diner. All tournaments in the interim are held at 308 N Euclid Ave, the old Kingside Diner space, the basement of The Chase Park Plaza Hotel, Il Monastero at Saint Louis University, or the World Chess Hall of Fame.
