21. Rb1
Anticipating the opening of the b-file.

 
21... Qd6
Black activates his last piece with an eye towards invading at a3.

 
22. Qc2
White activates his final piece as well. Both sides have completed their development. 2 sets of minor pieces have been exchanged. Black's edge in space allows his remaining pieces to be increase their activity more easily.

 
22... Reb8
Their is no penetration squares along the e-file, so black doubles along the b-file in preperation for activity there. Notice that white cannot match this activity due to his lack of space.

 
23. Rb2
White is attempting to double as well.

 
23... cxb3
The time has come to strike.

 
24. Rxb3
24. axb3 is better, but black plays b5-b4 in any case.

 
24... b4
The final break at last.

 
25. c4
Relatively best would've been 25. Re-b1. Now, white loses material.

 
25... Nxd4
Forking the rook and queen.

 
26. Qd1
White is lost.

 
26... Nxb3
Establishing a winnning material superiority.

 
27. axb3 Qc5
The rest is consolidation and then prosecuting the victory.

 
28. cxd5 Qxd5 29. Qa1
Crossing one's fingers and hoping, but their is a tactical problem.

 
29... Qxd2
Black can ignore the discovered check and wins another piece.

 
30. Nf3+
Discovered check is a powerful tactic, but it does not work in this instance.

 
30... Qc3
This may have been what white missed.

 
31. Qxc3+
The game is hopeless for white at this point.

 
31... bxc3 32. Nd4 Bxb3 33. Rc1 Bc4
Exploiting the back rank threat.

 
34. h3
If 34. Rxc3 Rb1 leads to mate.
