The Halloween Gambit
One of my favorite things to play as white is called the Halloween Gambit. It is a unorthordox opening that gives up some material to make sure that the white player gets rapid and i mean rapid development and a agressive pawn structure. This defense has its roots in the four knights defense but you could transpose but it's not the best. The gambit start out 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 (this is one way to get there.) 4.Nxe5. This offers the Knight for the development. Black accepts with 4...Nxe5 5.d4 and here Black has two feasable options and they are Nc6, and Ng6. Here is what it looks like.
These are the two best moves. If they play Ng4 you simply play e5 to make the black player to lose a knight.
