12. Ne2 
 | 
Prepares for the long castle and traps black's queen. | 
   
    | 
|   | 
| 
 | 
12... Bd7 
 | 
Conserves the bishop. | 
   
    | 
|   | 
| 
 | 
13. Nec3 
 | 
Allows white's queen to move to other areas, while keeping black's queen trapped, however, O-O is better. | 
   
    | 
|   | 
| 
 | 
13... Na6 
 | 
Black must account for his trapped queen by threatening the white queen if white attempts Bb2. | 
   
    | 
|   | 
| 
 | 
14. Qb7 
 | 
This move caught me off guard. I had expected white to move Bb2, but instead he threatens my rook and knight. This also allows black to save his queen. | 
   
    | 
|   | 
| 
 | 
14... Rb8 
 | 
Gives up the lesser piece. | 
   
    | 
|   | 
| 
 | 
15. Qxa6 
 | 
Of course. | 
   
    | 
|   | 
| 
 | 
15... Bb4 
 | 
Pins white's knight to his king. Enables black to escape with his queen intact. | 
   
    | 
|   | 
| 
 | 
16. O-O 
 | 
Moves out of the pin. | 
   
    | 
|   | 
| 
 | 
16... Bxc3 
 | 
Completes the queen's escape. | 
   
    | 
|   | 
| 
 | 
17. Qxa7 
 | 
MUCH better is Nxc3 | 
   
    | 
|   | 
| 
 | 
17... Rxb1 
 | 
Obvious. | 
   
    | 
|   | 
| 
 | 
18. Qa8+ 
 | 
Also obvious. | 
   
    | 
|   | 
| 
 | 
18... Ke7 
 | 
Forced. | 
   
    | 
|   | 
| 
 | 
19. Qa3+ 
 | 
Better is Qa7, pinning the bishop to the king. Checks black's king. | 
   
    | 
|   | 
| 
 | 
19... Bb4 
 | 
Removes the check on black's king and safely attacks white's queen. | 
   
    | 
|   | 
| 
 | 
20. Qa7 
 | 
A little too late. White sees his impending doom and resigns. |
