Mate in 23

In a game of speed chess I mated my opponent in 23 moves. My opponent, sammy2017 of the USA, played white. Here are the movies of the game along with my commentary:

1. d4 Nf6
2.Nf3 g6
3. e3 d5
4. Nbd2 Bg7
5. Bd3 0-0
6. h4 Bg4

White decides to push his h-pawn instead of castling. This is aggressive but leaves the king in the centre.

7. Nf1 c5

White wants to free his dark-squared bishop, but his knight isn't well-positioned. A better move is b3.

8. c3 cxd
9. cxd Ne4
10. N1h2 Be6

I decide to keep my bishop.

11. h5 Nc6
12. hxg fxg

I play fxg to open the f-file for my rook.

13. Bxe4 dxe4
14. Ng4 Bc4
15. Nxh7 Kxh7

White sacrifices his knight for a pawn. Nxe4 is safer.

16. Ng4+ Kg8
17. Nh6+ Bxh6
18. Rxh6 Kg7
19. Rh3 Bd3

My bishop is now very strong.

20. Qg4 Rd8

I offer to exchange rooks.

21. Rg3 Rh1+

Maybe black expects me to defend g6, but I go on the offensive.

22. Kd2 Qa5+

I have mate in one.

23. b4 Qxb4#

Whtie plays aggressively with moves such as h4 and Nxh7, but his attack is premature. His king isn't adequately defended. I take advantage to win the game.
