1. e4 c6 
 | 
The Caro-Kann is my favourite defense. | 
   
    | 
|   | 
| 
 | 
2. e5 d6 
 | 
I believe this is the best response to White's slightly uncommon 2nd move. | 
   
    | 
|   | 
| 
 | 
3. f4 
 | 
Dubious move, probably armed against the King Knight's development. 2.ed is the standard move. | 
   
    | 
|   | 
| 
 | 
3... Nh6 
 | 
Continuing development. | 
   
    | 
|   | 
| 
 | 
4. h3 
 | 
Another dubious move, weakening the Kingside. | 
   
    | 
|   | 
| 
 | 
4... Nf5 
 | 
Instead of continuing the development with 4-g6, it is more important to immediately take advantage of White's weak 4th move. | 
   
    | 
|   | 
| 
 | 
5. Nc3 Ng3 6. Rh2 g6 7. Nge2 Nxf1 8. Kxf1 dxe5 9. d3 
 | 
A pawn sac, but for what? 9.fe was much better, when I would have replied 9-c5, retaining a slight edge. | 
   
    | 
|   | 
| 
 | 
9... Bg7 10. Be3 O-O 11. g4 
 | 
A big mistake, further weakening the Kingside. Essential was 11.fe - Be5, 12. g3, when 12-Na6 would retain my advantage. | 
   
    | 
|   | 
| 
 | 
11... f5 
 | 
The winning move, breaking through the Kingside. | 
   
    | 
|   | 
| 
 | 
12. g5 exf4 13. Bxf4 e5 14. Be3 Nd7 
 | 
The imprudent 14-f4 would have been answered by 15.Bc5. | 
   
    | 
|   | 
| 
 | 
15. d4 
 | 
Another error, unnecessarily opening up the game, thereby hastening defeat. 15.Bd2 was necessary. | 
   
    | 
|   | 
| 
 | 
15... f4 
 | 
Of course! Now there's no defense. | 
   
    | 
|   | 
| 
 | 
16. Bf2 Nb6 
 | 
It's more important to activate all my pieces than to win a Pawn. | 
   
    | 
|   | 
| 
 | 
17. h4 
 | 
Holding on to the g-pawn creates a new weakness at g4. Much better was 17.de - f3, 18.Ng3 - Be5, 19.Qd8 - Rd8, prolonging the game. | 
   
    | 
|   | 
| 
 | 
17... Nc4 18. dxe5 
 | 
18.Kg1 - Bg4, 19. Qd3 would have offered more resistance. Although after 19-Nb2, it wouldn't be too hard to crash through White's position. | 
   
    | 
|   | 
| 
 | 
18... Nd2+ 19. Kg2 
 | 
19.Kg1 offers more resistance, as in 19-Nf3 , 20.Kh1 - Nh2, 21.Kh2. However, Black still wins by 21-Be5. | 
   
    | 
|   | 
| 
 | 
19... Bg4 
 | 
This is much better than the win of a piece by 19-f3 , which would have slowed down my attack after 20.Kh1 - fe2, 21.Qe2 - Nf3, 22.Rg2. | 
   
    | 
|   | 
| 
 | 
20. Ne4 
 | 
A piece blunder, when I was expecting 20.Kg1. In correspondence chess, a drop of a piece for nothing is unpardonable. | 
   
    | 
|   | 
| 
 | 
20... Nxe4 
 | 
White should resign now. | 
   
    | 
|   | 
| 
 | 
21. Qxd8 Raxd8 22. Nc3 f3+ 23. Kf1 
 | 
The more 'tenacious' 23.Kg1 would lose to 23-Nc3, 24.bc3 - Be5. |
