The Grenke Freestyle Chess Open began on 17 April and runs until 21 April, hosted at the Karlsruhe Convention Centre in Karlsruhe, Germany. The event is a nine-round Swiss tournament played under Freestyle Chess rules, where the starting position is altered while preserving castling rights.
Each round uses a classical time control: 90 minutes for the entire game, with a 30-second increment from move one. The tournament attracts both elite and aspiring players in a format that balances tradition and innovation.
