12...h5!
White hoped, after the natural 12...Nf6, to release his position with 13.f3. The move 12...h5 plays against this idea.
13.Nc3
In the case of 13.f3 h4 14.fxe4 hxg3 15.hxg3 Rh2, White is in trouble. That's the difference between playing 12...h5 and 12...Nf6. Now White has to abandon the idea of playing f2-f3.
If White tries to keep the h-file closed with 13.h4, his plan of f2-f3 will still be impossible, since the g-pawn hangs after ...Bd6.
13...Nf6 14.d3 h4 15.gxh4?! Rxh4

24.Qd1!!
White tries to eliminate his opponent's counterplay. What does Black have to do?
24...Rc4?!
This is the decisive moment of the game. Better is 24...Rb2.
