The Traxler Counter Gambit (a.k.a. the Wilkes-Barre Variation, due to Ken Williams's 1979 pamphlet based on games and analysis from his chess club in that Pennsylvania town) seems rather insane to the uninitiated: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5!? Like a lot of gambits, you have to see some games and try yourself to refute it before you will have any faith. Some recent online articles renewed my interest in the line and restored my faith that it would likely be worth some study, if I could find a spare month or so to do the analysis. NM Dan Heisman's CD (mentioned below) is highly recommended for the serious.
