In chess news, Fabiano Caruana is the present leader by points in the FIDE Circuit which is the path to qualify to play in the Candidates Tournament (the winner going on to play against the present World Champ, Ding Liren). Each player must play in a minimum of five eligible tournaments by the end of the year. The final FIDE Circuit point score will be calculated as the sum of a player’s five highest event scores. The spot in the Candidates goes to the highest-ranked Circuit player who has not already qualified from the FIDE World Championship Match.
