This is my serious annotation. This game comes from Philidor's Defense and reveals the power of opposite-side castling with a pawn storm.
1. e4 e5 2. Nf3 d6
Philidor's Defense

 
3. d4 exd4
Exchange Variation

 
4. Nxd4
An interesting fact about this move is that in GK's database, after this move white wins most games continued from this opening. Must say something about it.

 
4... Be7
Black is the first to break main line in this opening. On move 4! Maybe he should have learned his opening better if he wished to not get in trouble.

 
5. Nc3 c6
Another strange move out of an unusual defense. What is the point of c6? White appears to have an advantage here with more development and space. He has also created a backwards pawn on d6 unless he plans to push with d5, but this wastes time.

6. Bc4 Nf6 7. Bb3
I did not want to lose some of my center with 7...Nxe4 8 Nxe4 d5, and I wanted to keep pressure on f7.

 
7... Bg4
This is a pointless move as f3 is already part of white's development in Philidor's Defense and this gives white tempo.

 
8. f3 Bd7 9. Be3 Na6 10. a3
I thought that black's plan was to hit my bishop on b3 with his knight so I provided an escape square, but a better plan for black is 10...Nc7 with ...d5 to remove his weakness.

 
10... Nc5
My prediction comes through as black is not noticing the fact that he has a weakness on d6.

 
11. Ba2 Qc8
An odd place to develop the queen. It now only has three spaces to move to an none of them attack. The only benefit from this move is putting a useless battery on the c8-h3 diagonal.

 
12. Qd2 b6
What IS black doing with his pawns? He now has weaknesses on d6 AND c6 and his c pawn cannot move because of his knight.

 
13. O-O-O O-O 14. g4
Pawn storm! this move has been waiting to happen for a while once the king castles kingside right into an onslaught. Notice that I am completely developed, I have a battery on the c1-h6 diagonal, my rooks are connected, and my light-squared bishop points directly at black's king.

 
14... Ne8
Maybe black was trying to open up his dark-squared bishop to attack the storm, but it doesn't help.

 
15. Rdg1 Bf6 16. f4
An interesting move. Pushing my f-pawn removes a defender from g4 but is there a reason?

 
16... Bxg4
Black takes the bait.

 
17. f5
Cutting the string that connected the queen and bishop in half! The bishop is now going to be stuck on the wrong side of the pawn chain.

 
17... Bh5 18. h4 Qd7 19. Bg5
The bishop is the only defender of the kingside that is doing anything, and it seems logical to remove it.

 
19... Kh8 20. Bxf6 Nxf6 21. Rxg7
Exclam! A brilliant sacrifice! If 21...Kxg7, then 22 Qg5 Kh8 23 Qxf6 Kg8 24 Rg1 Bg6 25 fxg6 and forced mate is coming after 26 gxh7 Kxh7 27 Qg7#, or 22...Bg6 23 fxg6 and forced mate follows. A quicker death is 25...hxg6 26 Rxg6# all thanks to the bishop in the corner pinning the pawn.

 
21... Rfg8
Since capure is bad, this is the only move that can stop the looming pressure on g7.

 
22. Rgg1
Not yielding the file.
