Despite having a terrible structure, the position is around equal. Black has a fantastic bishop on e4 and White cannot put pressure along the files. Plan: ...Rfe8, ...Re6, and ...Qe7 unpinning.
A nice intermediate move, attacking the knight, before we protect the e4-pawn. And now Black has a couple of playable options
19...Na6 Another super important moment. Black is simply intending to capture on e4, so how do we stop that?
20.Bd3! Nb8 21.Rc7 Bxe4 22.Bxe4 Rxe4 23.Rhc1 +/- White has a much better position, with a lot of pressure on the c-file and the seventh rank.

A natural move, activating the rook along the seventh rank and increasing the pressure against f7.
Harikrishna 'trades' advantages: he trades his strong bishop, but in return, if we take a look at the remaining pieces on the board, he gets an active rook on the seventh rank and a better knight than the bishop. The e5-square is also now available for the knight!
The central knight joined by the weakness along the seventh rank gives White a clear advantage.
