One of your main weapons should be the gambit favored by Paul Morphy.
The first moves are 1.e4 e5 2.Bc4 Nf6 3.Nf3!? (Or 1.e4 e5 2.Nf3 Nf6 3.Bc4!?). Then if Black grabs the e-pawn, White brings out the other knight to c3. The idea is to sacrifice a pawn for rapid development and a good attack.
We will look at two games. In the first game, the gambit is accepted, in the second game, the gambit is declined.
ACCEPTED
DECLINED
