52.Ra6+?
Wasting an important tempo.
A complicated situation that needs to the accurate calculation. Nakamura has missed the only winning move:

White's plan is very clear: transferring his king to the e6 or g6-square.

Grischuk chooses a wrong way to cover the 7th rank.

White is a pawn down but the following bishop maneuver, typical in this French structure, will yield him a strong initiative.
19.Bc1!
Heading for the a3-f8 diagonal, where there is no black counterpart.
19...g6
Preparing 20... Nh7 in order to swap the strong knight on g5.
20.Ba3 Nh7 21.Nf3!
A logical retreat, by which White retains the knight for future attacking purposes and leaves its counterpart badly placed on h7.
21...Qd8 22.Qd2 Kd7?! 23.Rfb1 Nf5 24.Bc5 Kc6
In order to construct some kind of fortress on the queenside.
25.Qc1!+-
It is the queen's turn to exploit the a3-f8 diagonal.

Black is better thanks to his space advantage and more actively placed pieces. He now launches a strong bishop maneuver that will step up the pressure.
36...Be7!
Intending ...Bd8-b6 in order to seize the g1-a7 diagonal.
Also interesting was 36...Kh7!? intending ...Bh6, but the text is more aggressive.
37.N1d2
It is not easy for White to improve his pieces; e.g. 37.Qe2 Bd8 38.Ne3? Bxe4
37...Bd8 38.Kg1 Bb6 39.Qe2 Kg7
In such a superior position, Black has time for a few useful moves.
40.Nh4 Qd8 41.Ng2 Ng5!-+
Before White plays h3-h4.
