Carlsen, the world’s highest-rated chess player since 2010, will take a seat in Weissenhaus, Germany, to compete in freestyle chess, previously known as Chess960 and Fischer Random. The starting position of the back row pieces is randomized, removing a top grandmaster’s lifetime of memorization and theory on how to open a chess game.

This isn't just another chess tournament though, with a public spat between Carlsen and the promoters of the FCGT with FIDE in the build-up to the tournament.

Magnus Carlsen questioned the validity of classical chess as a measure of skill, favoring rapid chess. Gukesh acknowledged the quality of their championship match, while Carlsen ruled out a title clash.

Talking about the bitter battle between FIDE and Freestyle Chess, Carlsen said: “Right now it is very hard to have a relationship with any of the FIDE leadership. Speaking for myself and my father.”

The five-tournament series will unfold through the year, with Paris, New York, New Delhi and Cape Town being the other four host cities. It will end with the final competition from December 5 to 12

World champion D Gukesh made a steady start at the Freestyle Chess Grand Slam, adapting to the unique format amid rising tensions between FIDE and organisers, while Magnus Carlsen and other top players experience mixed fortunes.

Magnus Carlsen, a 34-year-old Norwegian, is among the greatest chess players of all time.

World Champion D Gukesh began his campaign at the Freestyle Chess Grand Slam tour with three draws and a lone loss, signalling that he is gradually coming to terms with the new format.
