What is Chess 9LX?

Chess 9LX is a tournament hosted by the Saint Louis Chess Club. It is played in the Chess 960 or Fischer Random format. Created by Bobby Fischer in the late 1990s, Chess 960 shuffles the pieces on the home rank, with 960 representing the number of possible starting positions. Players will not know the order of the home rank until 15 minutes before each round.
