Powerful Bishops

I recently won a game of speed chess with a pair of powerful bishops. My opponent was Asmadhu of the USA who played white. Here are the moves of the game along with my commentary:

1. e4 c5
2. c3 d6

White's second move is unusual.

3. d4 cxd
4. cxd Nc6

White has a powerful pawn centre but no piece development.

5. d5 Ne5
6. f4 Nd7
7. Nf3 e6
8. dxe fxe
9. Nc3 Ngf6
10. Bd3 Be7
11. 0-0 0-0
12. h3 b6
13. e5 dxe

White plays aggressively.

14.fxe Nd5

White has an advanced pawn on the e-file but it is isolated.

15. Qc2 g6
16. Nd4 Rxf1+
17. Kxf1 Qf8+
18. Kg1 Qg7

Here I should play Nxe5.

19. Nxe6 Qxe5
20. Nxd5 Qxe6

My queen can capture either of the white knights but I capture on e6 because I want to play Qe1+ on my next move. I expect white to play Nc7 on his next move.

21. Nc7 Qxe1+
22. Kh2 Bd6+

My dark-squared bishop now controls the b8-h2 diagonal.

23. g3

White blocks the check and then resigns. He sees that I can play Qxg3+. Then white must play Kh1. On my following move I activate my light-squared bishop with b7+. This gives my light-squared bishop control of the b7-h1 diagonal. My powerful bishops dominate the board. In reply black must play Qg2 and I then play Qxg2#.

In this game my bishops turn the game in my favour. White also has two bishops on the board but they are not nearly as dominant as mine. This game illustrates the power of the bishop pair.
