The tournament is a 10-player single round-robin played at classical time controls. Each player has 90 minutes for the first 40 moves and 30 minutes for the rest of the game, with a 30-second increment throughout. No draws by agreement are permitted.

There are no tiebreak games, with prize money and GCT points split evenly if players finish the tournament at the same score. If there is a tie at the top of the standings, the winner is determined by statistical tiebreakers in the following order: head-to-head score among tied players; total numbers of wins; and Sonneborn-Berger score.

2021 Sinquefield Community Contest


The inaugural Sinquefield Cup was held in 2013 as a four-player double round-robin. It was won by GM Magnus Carlsen, who later that year became world champion by defeating GM Viswanathan Anand. The 2014 Sinquefield Cup was a six-player double round-robin. GM Fabiano Caruana went on a historical tear, winning his first seven games and the overall tournament by three full points with 8.5/10.

In 2015, the Sinquefield Cup became part of the Grand Chess Tour and took its present form of a 10-player single round-robin. GM Levon Aronian was the winner. GM Wesley So won in 2016, followed by GM Maxime Vachier-Lagrave in 2017. Carlsen, Caruana, and Aronian shared first place in 2018. The 2019 tournament featured 12 players and was won by GM Ding Liren after he defeated Carlsen in a playoff.

In 2020, the tournament (as well as the entire Grand Chess Tour) was canceled amidst the coronavirus pandemic.
