Game of Errors

I played a game of speed chess against an opponent with a higher rating than mine. Even so, he made many errors. My opponent was Karst of Bulgaria who played white. Here are the moves of the game along with my commentary:

1. e4 c5
2. Bc4 e6
3. Nf3 d5
4. Bb5+ Nc6

I usually play Bd7.

5. 0-0 a6
6. Bxc6+ bxc6
7. exd cxd

Black helps to repair my pawn structure.

8. Ne5 Bd6
9. Nc6 Qc7

Now the knight is trapped.

10. f4 Qxc6
11. Qf3 Bb7

I prepare an exchange of queens.

12. Nc3 d4
13. Qxc6+ Bxc6
14. Ne2 Nf6
15. c3 0-0
16. cxd cxd
17. Nxd4 Bc5

White makes a mistake. He cannot save his knight.

18. Kh1 Bxd4
19. a4 Rfd8
20. d3 Bc5

I move my bishop to attack the pawn on d3.

21. b3 Rxd3
22. Ba3 Bxa3

With my material advantage, I am happy to exchange pieces.

24. Rxa3 Rad8
25. Raa1 h6
26. Rac1 Ba8
27. b4 Rd2
28. Rc5 Bxg2+
29. Kg1 Bxf1

Black can now resign but he decides to play on.

30. Kxf1 Rxh2
31. Kg1 Rb2
32. Kf1 Rd1#

To delay mate black must play Rc1. Black makes a number of errors in the game. He loses his knights with Nc6 on his ninth move and Nd4 on his seventeenth. These errors enable me to achieve a decisive victory.
