Eleven rounds will be played under the Swiss System, with 170 players participating from all continents: 114 in the Grand Swiss and 56 players in the Women’s Grand Swiss.

Held every two years, the Grand Swiss brings together many of the strongest chess players in the world and is considered to be one of the most difficult chess tournaments to win. The first Grand Swiss was held in 2019 in the Isle of Man and was won by GM Wang Hao, who scored 8/11. The 2021 edition was moved from the Isle of Man to Riga due to Covid restrictions on the island and was won by GM Alireza Firouzja in the Open and Lei Tingjie in the inaugural Women’s event. The 2023 Grand Swiss was won by India’s Vidit Gujrathi in the Open and Vaishali Rameshbabu in the Women’s competition.
