Black makes a blunder losing a bishop, but white later blunders two minor pieces, leading to a won endgame for black.  | 
| 
 | 
1. e4 c6 
 | 
A new opening for me: the Caro-Kann Defense. | 
   
    | 
|   | 
| 
 | 
2. Bc4 
 | 
?! Puts the bishop where blacks logical next move attacks it. | 
   
    | 
|   | 
| 
 | 
2... d5 3. exd5 
 | 
Better than 3. Bb3 dxe5. | 
   
    | 
|   | 
| 
 | 
3... cxd5 4. Bb5+ Nc6 5. Nc3 d4 
 | 
This seems Alekhine Defense-like.  I might play 6...Be6 and 7...a6. | 
   
    | 
|   | 
| 
 | 
6. Ne4 e5 
 | 
I guess I decided against the plan in the previous note and supported my d pawn. | 
   
    | 
|   | 
| 
 | 
7. d3 
 | 
Opening the line for his bishop.  We both miss the tactic Qa5 , winning the bishop. | 
   
    | 
|   | 
| 
 | 
7... Nf6 
 | 
The white knight seems to be in a good position, so I would like the option to remove it.  This move seems better than f5, leading to something like 8. Bxc6  bxc6 9. Qh5  g6, where the black kingside pawns seem weak. | 
   
    | 
|   | 
| 
 | 
8. Qf3 Bg4 
 | 
? I thought I was punishing the queen's overaggressive move and that Qg3 was the queen's only safe move.  However I missed black's tactic. | 
   
    | 
|   | 
| 
 | 
9. Nxf6+ 
 | 
Winning the bishop. | 
   
    | 
|   | 
| 
 | 
9... Qxf6 
 | 
Seems better than gxf6. | 
   
    | 
|   | 
| 
 | 
10. Qxg4 Bb4+ 
 | 
The situation I was hoping for if white had played 9. Qg3 is impossible, but there are some tactical possibilities here, although they do not play out. | 
   
    | 
|   | 
| 
 | 
11. Bd2 Bxd2+ 12. Kxd2 O-O 
 | 
Escaping the pin. | 
   
    | 
|   | 
| 
 | 
13. Nh3 
 | 
Protecting f2. | 
   
    | 
|   | 
| 
 | 
13... Rac8 
 | 
Protects the knight and prepares Nb4. | 
   
    | 
|   | 
| 
 | 
14. Ng5 
 | 
We both miss Qxf2 . | 
   
    | 
|   | 
| 
 | 
14... Qh6 
 | 
Pinning the knight. | 
   
    | 
|   | 
| 
 | 
15. Rae1 
 | 
Attacking e5.  Better was Bc4, pinning the f pawn so the knight can escape. | 
   
    | 
|   | 
| 
 | 
15... f6 
 | 
Winning the knight. | 
   
    | 
|   | 
| 
 | 
16. Qe6+ Kh8 
 | 
Not 16...Rf7? 17. Qxc8  | 
   
    | 
|   | 
| 
 | 
17. h4 
 | 
Better was f4, avoiding my 19th move. |
