22... Bxb1
So, what the hell, take the rook, attempt to even out the material disadvantage. Suddenly, one of the king's defenders is missing.

 
23. Qxb1
My LSB served its purpose, now it is dead.

 
23... Bg3
Now I can get to that square, and get rid of that rook. Possible defenses for white here are Qf1, Qe1 and... I think that's it. That rook is dead. I'm not fearing the attempted fork at Ne6, because I'm taking that rook on the next play.

 
24. Nb3
now this is just strange, and is a blunder in my opinion. Now the fork at Ne6 is a foregone possibility, and the rook is still dead.

Like so. Now, with my bishop at g3, the possibility of a back rank mate is open. But I have to get rid of one of those defenders. I can't just take that DSB with my rook though, since the knight is defending it. Also, I'm currently in danger of a fork at Ne4.

 
25. Kh1 Rfe8
Now I'm set to take the bishop, and threaten ...Re1 , which at the least would allow me to take white's queen.

 
26. Ne4
The threatened fork. I guess white didn't see my rook.

 
26... Rxe4
Die, knight.

 
27. Nc5
Another key defender gone. Still, this threatens a fork of the queen and DSB at e4 again, unless I mate before hand.

 
27... Qxd2
Here, I sacrifice the rook (more accurately, trade it for the bishop), knowing that afterwards I can mate on the back rank. Now, the only possible defense for white is Qf1 or Qg1, and that would be temporary. My response after that would be Re-e1.

 
28. Nxe4
Nope, the rook was too tempting. No matter, time for the back rank mate.

 
28... Qd1+
Forcing the take with the queen. The knight is no help here. After this move, white resigned.
