Well, it's Halloween and a nice little Frankenstein-Dracula variation (1 e4, e5 2 Nc3, Nf6 3 Bc4, Nxe4!?) in the Vienna Game seems appropriate. But I've never played that line. (I could offer up a nice Evans Gambit from the days when I opened games with 1.e4--but that wouldn't fit the season).
So how about a couple of mad dogs. I cooked this (obviously unsound) line up several decades ago.

The h-pawn as mad dog. Black has a number of easy refutations, but I still won correspondence games with it before the days of computer analysis. This game was played in the first round of an OTB tournament.
