FIDE has moved the Grand Swiss and Women’s Grand Swiss from the Isle of Man, where UK travel restrictions could have withheld many players from participating, to Riga, where currently a strong open is underway. The dates 25 October – 8 November remain the same as does sponsor Mark Scheinberg, who made his fortune in online gambling. The lists of qualified players are published. The top two of each event will qualify for the Candidates Tournament resp. Women’s Candidates Tournament 2022.
