In order to exchange queens and safeguard his king, Black is prepared to spoil his pawn structure. Indeed, the white rooks have difficulty becoming active and the bishop is just loose. Black, on the other hand, has a strong bishop on g7, a centralized king, and a central passed pawn to boot. Eventually, Anand proved his point in this game.

White is threatening to win material with 17.Bd6 The best way to deal with this is . . . to go your own way:

This was the idea behind the previous move.

Now we're down to the usual exchange sacrifice. Once again Black has two extra central pawns, though the d-pawn is further advanced, which leaves it vulnerable and also creates some weak squares.

Later White missed some more critical points and quickly lost the game.

There may well be good reasons to let the opportunity pass you by! Clearly (re-) capturing is the natural thing to do.

Oops! It's so easy to forget about this, as recapturing with 19.exd5 is the natural thing to do or expect.

Black also had to watch out for the 21.Nf6+ discovered check, winning the queen.
