Black should have centralized his queen and attacked the pawn on b2 with 58...Qe5!

White missed a golden opportunity to destroy his opponent's position:

Black brings up his last reserve to join the game. Now he can consider the plans like ...Nh7-f5 or ...e4.

19...Rgh8!
Now the idea of sacrificing the exchange on h3 becomes more obvious.
19...Bc6? would have been premature due to 20.Nd4, since Black's bishop, is too valuable a piece to be exchanged for the knight.
20.Rd1 Rh4 21.Qd2 f5! 22.Nd4
22.exf5!? Bc6
22...fxe4 23.Nxe4 Qxa5 24.Rb3 Qd5!

At first sight, White seems to be clearly better. All his pieces are active, the opponent has a weakness on a6, and the queenside pawn majority is an asset in any endgame. On top of this, the black forces are obstructed by the badly placed knight on e8.
21...g6!
Simple, yet very strong. Georgiev plans ...Ng7-f5 in order to improve his knight.
22.Bf1
A good square for the bishop, where it protects g2 and keeps watching the a6-pawn.
22...Ng7 23.Qe3?!
The immediate 23.Qh3 seemed more natural, although after 23...Nf5 Black hardly has any problems anymore.
23...Nf5 24.Qh3 Rfd8
In just four moves, the situation on the board has changed noticeably. Thanks to his strong central control Black already holds the upper hand.
