Resignation after 24 moves

In a game of speed chess against Francibrezner of Slovenia, I forced a resignation after 24 moves. Actually, I had mate in 22, but I missed it. In this game my opponent played black. Here are the moves of the game with my analysis:

1. e4 e5
2. Nf3 f5

My opponent decides to play a relatively unusual move.

3. exf Bc5
4. d4 exd
5. Nxd4 Nf6

Black is down a pawn, but ahead in development.

6. Be3 d6
7. Bc4 Bxd4

Bd3 protects the extra pawn, but Bc4 prevents castling.

8. Bxd4 Bxf5
9. 0-0 Nc6
10. Re1+ Ne7
11. Bxf6 gxf6
12. Qh5+ Bg6
13. Qe2 c6

Black is in a very defensive role. The queen protects the knight on e7.

14. Be6 Bf7
15. Bxf7+ Kxf7

The black king is exposed.

16. Qh5+ Ng6
17. Nc3 Qb6

I must decide whether to protect the pawn or generate offence.

18. Ne4 Qxb2
19. Nxd6+ Kg7
20. Nf5+ Kf8
21. Qh6+ Kf7

Black's move is forced. Here I have mate with Qg7, but I miss it.

22. Nd6+ Kg8

Again black's move is forced.

23. Rab1 Qc3

My original idea is to play Rxb7, which threatens mate on g7. I can't play this, however, because if I do black plays Qxe1#. I then notice a very strong move.

24. Nf5

Black resigns because he can't prevent mate on g7.

Black plays an unusual second move for quick development. However, I prevent his king from castling and keep him on the defensive. In the end, his king is too exposed to prevent defeat.
