White has three options from the above position. Probably the strongest, and the one I like as white, is 3.f4, the Vienna Gambit. The second line, and one worth knowing from both sides of the board, is 3.Bc4, the Vienna Game. Last, and perhaps suited for great positional players, is the Miesis Variation, 3.g3. Returning to the Gambit line, 3...d5 4.fxe5 Nxe4 reaches a parting of the ways. Both 5.Nf3 and 5.d3 are playable.
