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.}
1...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.}
2...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.Nf3
{C42 Petrov's Defense / Three Knights Game (transposed).}
3...Nc6
{C46 Four Knights Opening (transposed).}
4.Bb5
{C60 Ruy Lopez (Spanish) / Berlin Defense (transposed).}
4...h5
{Out of Opening Book. Bb4 would have been in the Ruy Lopez (Spanish) / Berlin Defense opening line.
