Board Position
Originally called the Hamppe Opening after Swiss player Carl Hamppe, a government official in Vienna who first popularised it in the 1840s. White's idea is to play a form of King's Gambit (P-KB4) but to add first the development of the Queen's Knight (move 2 shown left).
White develops the QKt first so as to reserve the opportunity to play P-KB4 (in both the main line and the immediate variation of the Vienna Gambit) before starting a King's-side attack with pressure down the King's Bishop's file. The strategic idea is that P-K4, Kt-QB3, B-B4, Q3, KB4 should let him advance the KBP without risking the complications of the King's Gambit itself.
The risk in the Vienna is that, under no immediate attack, Black has time to counter in the centre with an eventual P-Q4 and thus secure full equality.
