11.c4!
This looks rather anti-positional as Black can capture on c4 and secure the d5-square for his knight. If only chess was that simple! The text move is by far the most convincing way to open things up. 11.a4 b4 doesn't do quite the same job, as the queen cannot go to a4 and there still aren't any open lines.
11...bxc4 12.Ne5
Black now has difficulty preventing the queen check on a4. This checking idea, coupled with the bishop pinning the knight on f6, already leaves him in an uncomfortable position. The Ne5/Qa4+ combo (or even Ne5/Bb5+) is another useful theme to remember.
12...Be7 13.Qa4+ Nd7 14.dxc5!!
A great piece sacrifice to open the d-file and keep up the pressure. White could have retained the initiative with 14 Bxe7, but Nisipeanu spots that he has an even better way to proceed. Even if you see a good move, you should always be on the lookout for a better one!
14...Bxg5 15.Rad1 Bd5
Attempting to block the d-file. 15...Bc8 could hardly be considered as an alternative!

12...a6!
Black's idea is to try for the ...b5 pawn break to attack White on the queenside. If White allows this, then ...b4 attacking the a3-pawn will open at least the b-file towards White's king. Black's kingside pawns remain untouched so White will find it harder to make progress with the same pawn storming idea, as seen in the game.
13.Be2
Trying to keep the lines closed on the queenside with 13.Nb3 Qb6 14.c5 is okay, but Black can get in ...b6 anyway at some point, e.g. 14...Qa7 15.e4 d4 16.Na4 e5!.
13...b5!
Offering a pawn sacrifice to open the a- and b-files.
14.cxd5
Accepting the pawn with 14.cxb5 axb5 15.Bxb5 Bd7 is too dangerous for White, as Black has three (!) open files down which to attack.
14...exd5 15.g4 Be6 16.Nb3 Qb6 17.g5 Ne4!
Not losing a pawn as Black has tactics against b3.
18.Nxe4 dxe4 19.Rxd8+ Nxd8
Opening the c-file for the rook and leaving White no time to catch his breath.
20.Kb1 Rc8 21.Qd1 Nc6
The knight returns to the action. Black is better coordinated as most of his pieces are already looking towards the white king, and he can set about using the a3-pawn as a target of attack.
