​

The Saint Louis Rapid and Blitz chess is the third stage of the 2018 Grand Chess Tour. The 10-player chess tournament takes place in the Chess Club and Scholastic Center of Saint Louis from 11-15 August and sees tour regulars Aronian, Caruana, Nakamura, Anand, Karjakin, MVL, So, Mamedyarov, Grischuk and wild card Dominguez.

The chess prize fund is $150,000, with $37,500 for 1st place. The rapid section is a single round-robin with 3 rounds each day on the first 3 days at a time control of 25 minutes for all moves and a 10-second delay from move 1. The final 2 days are a blitz double round-robin, with 18 rounds of 5 minutes + 3-second delay blitz.

Rapid chess games count double, with 2 points for a win and 1 for a draw. A tie for first place will be decided in a 2-game Rapid mini-match (10min + 5sec delay), only between the top two, and if necessary an Armageddon game (5 vs. 4). The playoff takes place shortly after the last round.
