14... Bf7 15. Qd2 
 | 
Not only do I threaten Black's knight, but also have a sneaky attack on the h6 pawn. | 
   
    | 
|   | 
| 
 | 
15... Nf6 
 | 
Threatens my e-pawn to counter my threat on his h-pawn. | 
   
    | 
|   | 
| 
 | 
16. Bxh6 fxe4 
 | 
Taking with the knight allows me to trade my unimportant c3-knight for his kingside defending knight. | 
   
    | 
|   | 
| 
 | 
17. Bxg7 Kxg7 
 | 
If exf3, then Bxf8 wins an exchange. | 
   
    | 
|   | 
| 
 | 
18. Qg5 
 | 
This counterthreat is much stronger than passively moving my knight. | 
   
    | 
|   | 
| 
 | 
18... Be8 19. Nh4 
 | 
I'm not interested in taking on e5, which complicates the game. I'd much rather play it safe while I have an attack going. | 
   
    | 
|   | 
| 
 | 
19... Ned5 
 | 
Black wants to block my rook's escape path and challenge it's defender, the c5-pawn, but my attack will be complete before then. | 
   
    | 
|   | 
| 
 | 
20. Bc4 
 | 
Putting more pressure on d5. | 
   
    | 
|   | 
| 
 | 
20... b6 
 | 
Black is underestimating my kingside attack, and will lose quickly. | 
   
    | 
|   | 
| 
 | 
21. Nf5+ 
 | 
I don't need to answer Black's threats when I have strong piece play against his king. | 
   
    | 
|   | 
| 
 | 
21... Kh8 22. Nxd5 Nxd5 
 | 
Taking with the pawn allows me to win a piece by taking on f6. | 
   
    | 
|   | 
| 
 | 
23. Qh6+ 
 | 
Attacking the king and rook. | 
   
    | 
|   | 
| 
 | 
23... Kg8 24. Rxd5 
 | 
Black may as well resign now. I'm threatening discovered check, and once he takes my rook, it's mate in 2. | 
   
    | 
|   | 
| 
 | 
24... cxd5 25. Bxd5+ Rf7 
 | 
Bf7 and Qf7 leave Black with the same fate. | 
   
    | 
|   | 
| 
 | 
26. Qg7# 
 | 
If you didn't see this mate, then you should probably start practicing to recognize pinned pieces better. |
