Magnus Carlsen decised not to defend his title as World Classical Chess Championship this November setting the default stage for Ian Nepomniachtchi or Ding Liren to play for the title. Carlsen is the better player, yet like Bobby Fischer he has found some reason not to play; perhaps he wants to attend medical school or prepare for the next salmon season.
If Mr. Carlsen decides to continue with chess he may start a new league rival to FIDE comparable to the Saudi formation of a new chess league. A divded title did exist around the turn of the millenium and the former chapmion and alternative G.O.A.T. chess star Garry Kasparov was in it. Maybe the Saudis will finance a new chess tour to rival F.I.D.E., or not.
