analysed.] which will lead us back to those openings in which
White plays P-Q4 on his second move. After 2. P-Q4, PxP, White
has the option of sacrificing two pawns to obtain a very rapid
development 3. P-QB3, PxP; 4. B-QB4, PxP; 5. QBxP. It may now be
just possible for Black to avoid the many threats which White can
bring to bear with his beautifully placed forces, perhaps by
giving back one or both of the pawns gained. But this question
can only be of interest to us if there is no opportunity of
adopting a simple line of development at the outset. As it is,
this opportunity is not wanting. All that Black needs to do is to
push on his Queen's Pawn as soon as possible, thus freeing his
own Queen's Bishop.

2. P-Q4 PxP
3. P-QB3 P-Q4
