[Event "USA-01 Congress Grand Tournament"] [Site "New York 1/8 finals"] [Date "1857.??.??"] [Round "6"] [White "L. Paulsen"] [Black "Morphy"] [Result "0-1"] {Annotations by Chessmaster: Grandmaster Edition Auto-Annotator. 10 seconds per move.} 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... Nc6 {C27 Vienna Game.} 3. Nf3 {C27 Vienna Game.} 3... Bc5 {C46 Three Knights Game. Black responds to 3. Nc3, a tame move, with Bc5, the Three Knights Game, in which White gains the initiative with a tactical finesse.} 4. Bb5 {Out of Opening Book.
