The 2021 FIDE Chess.com Grand Swiss Tournament and Womenâ€™s Grand Swiss will be held from the 25th of October to the 8th of November at the Hanzas Perons Cultural Centre in Riga, Latvia.

The winner of the Womenâ€™s Grand Swiss will qualify directly for the Women Candidates and four best players will qualify for the next yearâ€™s Womenâ€™s Grand Prix.
Eleven rounds will be played under the Swiss System, with 164 players participating from all continents: 114 in the Grand Swiss and 50 players in the Womenâ€™s Grand Swiss.
The average rating of the players in the Grand Swiss is 2647, making this the strongest Swiss-system chess tournament in the world.
The total prize fund is $550,000, with $425,000 for the Grand Swiss and $125,000 for the inaugural Womenâ€™s Grand Swiss.
The first Grand Swiss was held in 2019 in the Isle of Man and was won by GM Wang Hao, who scored 8/11. Because of COVID-19, the 2020 edition of the event was cancelled. The 2021 edition was initially planned for the Isle of Man but was moved due to COVID-19 regulations in the UK and the Isle of Man which would have required many players to isolate for 10 days.
Time control: 90 minutes for 40 moves, followed by 30 minutes to the end of the game, plus 30 seconds increment per move starting from first move.
