So far I have the Dudweiler gambit. F4, D5, G4, BXG4. Yes, G4 is a book move. Somehow.
And the traxler- but if you know theory it should be a fine game
Dudweiler : -2.4
Traxler : (When the sacrificed bishop is not taken) +1 but if the bishop is taken its +0
No book opening that isn't considered dubious is really going to give either side much of an advantage outside of space.
