With four decisive rounds on view, leader Ian Nepomniachtichi and Anish Giri remained in the race to become Magnus Carlsen's challenger for the World crown after scoring emphatic victories in the 12th round of the Candidates Tournament in Yekaterinburg, in Russia, on Saturday.

Nepomniachtchi defeated a struggling Wang Hao to reach eight points before Giri, with his third win in four games, ended top seed Fabiano Caruana's title-aspirations. Maxime Vachier-Lagrave moved to the third spot by beating Kirill Alekseenko while Ding Liren redeemed some pride by stopping Alexander Grischuk.

Two more rounds remain after the rest day on Sunday.
