15...Bh6!
Suddenly, the pathetic piece on g7 has become active.
16.Bd3
Black was threatening to win the e-pawn by 16...Bxd2 followed by 17... fxe4, so White gives this pawn more support.
16...Qc7 17.bxc5 bxc5 18.exf5 gxf5 19.Bc2
White now has the option of getting his own bad Bishop outside the pawn chain with Ba4.
19...a6
Black takes away the b5-square from the White Knight.
20.Nde4?
White would like to play 20.Ba4 but that would lose a pawn after 20...Qxa5. The move White actually plays is tricky (it uncovers an attack against h6 via the Bishop on c1), but it only leads to exchanges that speed up Black's kingside attack.
20...Bxc1
Black is delighted to trade his bad Bishop for White's good one.
21.Nxf6 Rxf6 22.Rfxc1 Raf8 23.Rb6 Bc8
Black defends the a-pawn (why give anything away?) and is finally ready to go after the White King.
24.Ne2 f4!
With his dark-squared Bishop gone, Black is happy to push this pawn. Notice how this advance also frees the c8-h3 diagonal for his light-squared Bishop.

19.Bh3!
My Bishop on g2 was bad, so I move it to h3 and accomplish two goals: I get it outside the pawn chain and give it a new lease on life on the h3-c8 diagonal; and after I play f5-f6 or fxg6, I will trade light-squared Bishops, swapping my bad Bishop for Black's good one. The exchange leaves Black with just one Bishop – a bad one. The strategy here is to deprive Black of control of both colored squares: If you envision battling your enemy with your Knights, don't allow him to own two Bishops because they control both colored squares (Seirawan).

"Chess can never reach its height by following in the path of science ... Let us, therefore, make a new effort and with the help of our imagination turn the struggle of technique into a battle of ideas."
