In the first round of the day, Mamedyarov had escaped with a draw against Nakamura, who failed to find the correct rook move in the following endgame.
In over 4 hours in front of the camera, Karsten Müller presents to you sensations from the world of endgames - partly reaching far beyond standard techniques and rules of thumb - and rounds off with some cases of with own examples. Nakamura vs. Mamedyarov - Round 6
Since the black king is so far from the action, 54.Rf4 was enough to win, while 54.Rb8 actually fails against the correct defensive technique, as GM Karsten Müller demonstrates in his annotations below.

Naka got his one win of the day in round 7, when he did convert from a superior endgame in which his rival’s bishop was imprisoned on the first rank.
Adhiban vs. Nakamura - Round 7
As GM Müller notes, Adhiban needed to free his bishop at once with 53.f3, although even in that case “the road to a draw is very narrow”. The Indian’s 53.Ra1, on the other hand, was quickly punished by Nakamura.
