Fighting for a total prize fund of $150,000, the participants will each face off once during nine rounds of rapid Chess 960 (aka Fischer Random Chess).
The event kicks off on October 27th with Ultimate Moves, a fun exhibition event featuring Saint Louis Chess Club co-founder Rex Sinquefield, Garry Kasparov, and the rest of the Champions Showdown: Chess9LX field, participating in a high-stakes team blitz match.
For spectators in Saint Louis, follow the tournament round by round with our Grandmaster in Residence from 2:00 PM to 6:00 PM daily. Live commentary is open to all members and guests and includes complimentary snacks and beverages.
For online viewers, tune in for live commentary from GM Yasser Seirawan, GM Cristian Chirila, and IM Nazi Paikidze on Saint Louis Chess Club’s YouTube and Twitch channels.

Chess 9LX Pre-Tournament Predictions
The pre-tournament win probability algorithm was computed using a weighting of URS, 960 performance, and quick chess ratings. No head-to-heads were considered given the low number of 960 games between players. The probabilities are based on 15,000 tournament simulations.
