pieces; P-d6 blocks the Bishop f8; B-d6 obstructs the Queen's
Pawn and Q-f6 or Q-e7 hinders the development of the Knight or
the Bishop respectively. Now, it can readily be seen that after
(2) ..., Kt-c6 White may want to place his King's Bishop on b5,
for with this move he repeats indirectly his attack on the King's
Pawn through the threat to remove the protecting Knight. It is
true, that this threat needs no attention as long as White's
King's Pawn is not protected (for instance: (3) ..., Kt-f6; (4)
Bxc6, Pd7xc6; (5) Ktxe5, Q-d4 attacking Knight and Pawn at the
same time and thereby regaining the Pawn) but as soon as White
has defended the Pawn--with P-d3 may be--the Bishop b5 is at work
and Black must seek additional protection for the Pawn e5.

If White, on his second move, plays B-c4, he attacks the Pawn f7.
This Pawn is protected by Black's King and so he need not be
defended any further; but Black must be on the alert against a
concentration of some more white men on f7. White could try (3)
Q-f3 or Q-h5. However, Black would then have time to defend
himself with Kt-f6 or Q-e7 respectively.

Therefore, on the second move, Black may make any developing
move; he could, of course, play (2) ..., Kt-f6, preventing
White's Queen from going to h5, but this is unnecessary, as Q-h5
would be a very bad move, placing the Queen on a square from
which she is bound to be chased away very soon. For instance: (2)
...., B-c5; (3) Q-h5, Q-e7 (not P-g6 on account of Qxe5 attacking
the King and the Rook at the same time). Now, whatever White
plays, he will have to retire again with his Queen as soon as
Black attacks her with Kt-f6, and so he loses his birth-right of
attack; for it will be Black who is a move ahead in the
