user33007: When a world chess champion like Carlsen decides not to defend the title, how does FIDE determine who the new champion will be? Is it just the winner of the Candidates tournament?

user27380: The winner of the candidates plays a WC match against the runner-up of the candidates. The World Champion who does not defend the title loses the title to one of these two players.
Therefore, the next World Champion after Carlsen will be Nepo or Ding.
