Have you tried it? It would be cool with some games!
Halloween Gambit ♣

I programmed an opening book for my bot to play it online, and it never did lose with it, but some games were pretty close!
The problem is that I just don't play e4. I used to, but not these days. :)

I would, if the 4 knights game came up.
I once played the Halloween Gambit in a blitz against Larry Evans and came out in an endgame where I had a rook, queen, and some pawns against a rook, queen, knight and some pawns. But the material was even because I had three more pawns than him. Then I blundered and lost my rook and resigned.
The actual Halloween Gambit opening plays out as follows: 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Nxe5.
Here is my newest article - this time on an exciting and daring gambit!
