Here the opening moves are again: 1. P to K 4, P to K 4; 2. P to K B 4, P
takes P; 3. Kt to K B 3, P to K Kt 4. If White plays 4. B to B 4, Black can
play either 4. ... B to Kt 2, thus consolidating his King's pawns, which
are difficult to break up, or 4. ... P to Kt 5, with the consequences shown
in the Muzio and Salvio. To obviate this, White plays now 5. P to K R 4.
Black's Knight's pawn cannot be defended with P to K R 3, the Bishop not
being yet at Kt 2. Therefore Black's best course (B to K 2 not being good)
is 5. ... P to Kt 5, to which White replies 6. Kt to K 5--the Kieseritzky,
or 6. Kt to Kt 5, the Allgaier, to be considered subsequently.

to K B 3.
