This move is very strong! The white queen should keep an eye on f2. That is why Qd2 is mandatory. The problem for White is that when the knight arrives to e5 later, f3 will be easier to access!

Capturing the e5-pawn with the knight in the next move and we can see how the light squares are extremely weak. Black is much better.

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.
