The FIDE Candidates Tournament finished yesterday and we now know that Ian Nepomniachtchi is Magnus Carlsen’s next challenger for the title of World Chess Champion. Malcolm Pein begins his coverage of the key moments and games from the tournament in today’s Daily Telegraph chess column, with the emphasis on Caruana’s fine start.
Malcolm Pein on…Caruana’s Fine Start
Fabiano Caruana moved back into contention when the Candidates Tournament resumed. The former title challenger defeated Maxime Vachier-Lagrave in a game that had everything.
A deep opening novelty involving a sacrifice of three pawns and a piece was met by tenacious defence. MVL navigated huge complexity to escape into an endgame and set up a fortress, before erring in the sixth hour.
