Thar Gambit (Rate a new opening)

And for 2 bishop moves tell why you sacrifice a pawn in kings gambit
1) To divert the e-pawn away from the center so that white can play d4 next.
2) To open up the f-file for an attack on the black king if white is able to capture the f-pawn or if another pawn is sacrificed on g3.
3) To gain a development advantage.
it is also a gambit
No... it isn't. What you have is a system of moves that you hope that you can play as white. You aren't even accounting for how black can or will respond.
In order for a gambit to be a gambit, there needs to be a sacrifice of material (pawn or piece), to gain some compensation (Typically an advantage in development or to gain control of the center). You are sacrificing your development (not material), to create a bind in the center. That is called a waste of your first move advantage, not a gambit.
