I just love that Halloween style!
Here's a quick game in the Halloween gambit where black makes a common inaccuracy that I was able to capitalize on thanks to my preparation!
1. e4 e5
2. Nf3 Nc6
3. Nc3 Nf6
My favorite dubious gambit begins.
4. ... Nxe5
5. d4 Ng6
6. e5 Ng8
7. Bc4 Be7??
The standard move for black here is Bb4!! which is considered to be the mainline and possibly the Achilles heel of the entire line.
Then black is doing alright after 8. Qf3 Bxc3 9. bxc3 Qe7
Notice that it is very difficult for white to find compensation for the gambit (although I've had some success with both 10. a4 and 10. 0-0)
8. Qf3 f6
Now it looks like black is ruined. There is one try to save the game.
9. ... d6
Opening a path for the king to escape.
10. Qf7+ Kd7
Recently I made the mistake of playing 11. Be6? in this position which allowed black to slip away and he eventually was able to drum up counter play and score a win against me. This loss allowed me to find the better move e6! and the subsequent ending to follow!
11. ... Kc6
12. b4 is not awful, but d5+ is much better leading to a very neat mating idea. Now white will trap the king on the queenside where none of his pieces can help him.
12. ... Kc5
13. Be2 Nf4??
Unfortunately black didn't have anything better. Now it's a forced mate in 3.
14. Be3+ Kb4
15. a3+ Ka5

I have a lot of fun and success playing this in blitz formats against unsuspecting and unprepared opponents! Seriously, give it a shot!
