Victory in 14 moves

In a game of speed chess, my opponent resigned after fourteen moves.  He was Poulantzas of France, who played black.  Here are the moves of the game along with my commentary:

1. e4 e5
2. Nf3 d6
3. Bc4 Bg4

I can now castle kingside.

4. 0-0 Bxf3

Black makes a bad move.  By capturing my knight, he removes the threat of the pin on my knight.  He also allows me to advance my queen to a good square and put pressure on the f7 square.

5. Qxf3 Qf6

Black wishes to exchange queens, but I do not cooperate.  If I exchange, I help him to develop his knight and we both have one developed piece.  By refusing to exchange, I maintain my advantage in piece development-  I have two developed pieces and black has one.

6. Qb3 b6

Black prevents Qxb7.

7. d4 exd

I sacrifice a pawn to open a diagonal for my bishop and allow the e-pawn to advance.

8. f4 Nc6

Black can now castle queenside, but my next move prevents it.

9.  e5 dxe
10. fxe Qe7

The move Qxe5 is risky because the black king is very exposed.

11. Bxf7+ Kd8
12. Qd5+ Qd7

Once again black wishes to exchange queens but I have a better move.

13. Bxg8 Qxd5

I win a piece.

14. Bxd5 Bc5

If I do not move my king, Black can now play e3+ on his next move. However, the discovered check is not dangerous.  I can play Bxc6 on my next move.  Since this leaves me two pieces up, black decides to resign.

Black makes a number of bad moves in this game.  The move Bxf3 is bad because it is too committal.  It gives up the bishop at a very early stage of the game, removes the pin on my knight and develops my queen. The move Qf6 is also bad because it places the queen on an ideal square for the king knight.  Black's lack of development and exposed king are the reasons for his early resignation.
