Your Favorite Gambit.
Not much of a gambiteer but I hazard the Fantasy Variation on occasion
1.e4 c6 2. d4 e5 3. f3
Also the Icelandic Gambit as black in the Scandi.
I like the Marshall Gambit, King's Gambit and the Evan's Gambit (but the Marshall is hard to pull on people as they tend to avoid it). All of them give good attacking chances to the gambiteer and is suprising to a lot of people. The only problem is that the attacker should act quick and accurately or the other side will hold on to the material (this is why I like the Marshall as the attack can die down, then regroup for a second wave!).
My favorite gambit is the halloween gambit!
