The encounter lasted 41 moves, but challenger Ian Nepomniachtchi was unable to achieve the advantage necessary to begin to claw his way back into the final.

Nepomniachtchi, playing under a Russian Chess Federation flag, now trails Norway's Carlsen 3.5-6.5.

With four games remaining, time is running out for Nepomniachtchi if he is to stage a remarkable comeback.

Carlsen is seeking to win the world title for the fifth time in succession, having held it since 2013.

The Norwegian had won two games in a row heading into today's contest.

Tomorrow is a rest day.
