Here the opening moves are: 1. P to K 4, P to K 4; 2. P to K B 4, P takes
P; 3. B to B 4. The Bishop being developed at this stage, instead of the
King's Knight, gives the Opening its name. Its special feature is that
White exposes himself to a check, which compels him to move his King, and
thus loses the privilege of castling without gaining such an immediate
attack as in the Salvio. But though White thus gives up the attack
temporarily, he is able to reassume it with intensified vigour, owing to
the exposed position of the Black Queen. The check with the Queen is
therefore now only {401} resorted to in conjunction with 4. ... P to Q 4, a
counter-gambit which furthers Black's development.
