1. e4 ... ;B00 King's Pawn Opening. The King's Pawn
;opening move is both popular and
;logical. It controls the center, opens
;lines for both the Queen and the Bishop,
;and usually leads to an open game in
;which tactics, rather than slow
;maneuvering, predominates.
... e5 ;C20 King's Pawn Game. Black responds
;symmetrically, making a direct challenge
;to the central squares.
2. Nc3 ... ;C27 Vienna Game. The Vienna Game offers
;transpositions to the King's Gambit
;depending on Black's response, but is
;somewhat indirect.
... Nf6 ;C26 Vienna Game / Falkbeer Variation.
;This is one of those romantic openings
;from the last century when little was
;known of defense. Nowadays, 3.Bc4 Nxe4
;is equal (no advantage for the first
;move), 3.f4 d5 is slightly to Black's
;advantage, and 3.g3 Bc5is 8% in Black's
;favor. Only 3.Nf3, which is tame, yields
;White any chance of minimal advantage.
3. d3 ... ;Out of Opening Book. g3 would have been
;in the Vienna Game / Mieses Variation
;book opening.
