Aronian employs a very interesting positional idea, trading his fianchettoed bishop for a knight. What he gets in return are doubled pawns on the c-file which become easy targets and weaknesses to attack.

There we go!

Now White has a very easy plan, to recycle the e1-knight and attack the pawns along the c-file.

Trying to eliminate one of the defenders of c5.

All the white pieces will coordinate along the c-file with tremendous pressure.

Dvirnyy gives Black now a couple of options: to leave a centralized knight on e5 or to trade it and double pawns.

This doubling of pawns favors White: the f-file has been opened where there is pressure against f7 and White is also controlling important squares such as f6.

And the combination queen (on c2), bishop and knight on f4 is super dangerous for Black.

White doubles their pawns in order to put pressure along the new semi-open file. Moreover, suddenly the a4-knight is perfectly placed, putting an aye on the c5-square and stopping Black's counterplay based on a4.
