Black has gained a second pawn for the exchange and went on to convert his advantage.

Again ignoring the threat!

This is it: Black has time to grab a second pawn.

And now Anand made a move which most of us would have found difficult:

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.
