Round four at the FIDE Candidates Tournament saw four draws ©FIDE

Competition resumed at the International Chess Federation (FIDE) Candidates Tournament today, although the standings were unchanged after a series of stalemates in Yekaterinburg.

Russia’s Ian Nepomniachtchi headed into the fourth day of competition as one of the tournament co-leaders, along with France’s Maxime Vachier-Lagrave and China’s Wan Hao.

Nepomniachtchi faced the prospect of defeat against the United States’ Fabiano Caruana at the Hyatt Regency Hotel.

Caruana, the 2018 winner of the tournament, missed the opportunity to win the tie with the contest ending in a draw.

There was also a missed opportunity for Vachier-Lagrave, as the Frenchman missed the chance to defeat Russia’s Alexander Grischuk.

Wang Hao drew with Russia’s Kirill Alekseenko, while China’s Ding Liren also halved a point with the Netherlands’ Anish Giri.

The day of draws keeps Nepomniachtchi, Vachier-Lagrave and Wang top of the standings on 2.5 points.

Caruana and Grischuk moved on to two points, with Liren, Alekseenko and Giri now on 1.5 each.

The fifth of 14 rounds of matches will take place tomorrow.

The final round of games is scheduled to conclude the tournament on April 3.

Participants are competing for the largest amount of money ever at a Candidates Tournament with the prize pot standing at €500,000 (£453,000/$556,000).

The tournament will decide who will face Norway's Magnus Carlsen at the World Chess Championship later this year.

The tournament is one of the few events taking place amid the coronavirus pandemic, which has largely decimated the sporting calendar.
