What is your favorite gambit, dubious or otherwise?

@Otienimous Is that where you live? EDIT: Didn't see the rational in the study.

@Mehzinho I don't go into those lines but I do know there are already a lot of videos of the halloween gambit.

@Unkingly Not at all, I have never even visited that place. I was reading about it in a book just when I got hit with an idea of 2...e5. It was the inspiration (I explained its mechanism in the study), so I proposed to name the gambit like that.

Queen's Gambit definitely, thought some might argue its not a true gambit as you can easily win the pawn back

As black I don't really know yet

Korchnoi's Gambit in the French Defense is a fun one for White - you sacrifice a central pawn to end up with active pieces pointed at the Kingside, and outpost on d4, an open c-file, while still keeping a fairly solid position and decent pawn structure.
