Freestyle Chess Grand Slam tour boss Jan Henric Buettner and all-time great Magnus Carlsen have called on International Chess Federation (FIDE) president Arkady Dvorkovich to resign after talks over an agreement about the new series fell through.

“The organizers of the “Freestyle Chess Tour” fully deleted from its Regulations the reference to the “World Championship” title. Following this change in the regulations, players wishing to participate in the 2025 “Freestyle Chess Tour” are no longer required to sign the waiver note,” said the updated FIDE statement.

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.
