Black's Response to King's Pawn Openings: Variation II

(3) Kt-f3 Kt-c6

Most players would be tempted to play P-c5 instead. But this must be bad as it is a Pawn move which is not necessary. Black does not need to defend the Pawn d4 as he is a Pawn ahead; and the development of the pieces is much more valuable than the advantage of a Pawn. White would obtain a far superior position with (4) P-c3, Pxc3; (5) Ktxc3, after which Black cannot hope ever to free its game by P-d5.

(4) Ktxd4 Kt-f6

It would be bad to exchange Knights on d4 because White's Queen would be brought up into a dominating position from which she could not easily be driven away.

(5) Kt-c3 B-b4

This attacks again the Pawn e4. Relieving the pin by (6) B-d2 would be no protection as Black could exchange on c3 and then take the Pawn. Therefore, White must defend the Pawn with another piece. The Bishop f1, which has to be developed in any case, offers himself naturally for this purpose, but B-d3 is not possible as long as the Knight d4 has to be kept protected by the Queen. Hence, it is necessary first to exchange the Knight.

(6) Ktxc6 Pb7xc6
(7) B-d3 P-d5!

Again Black has succeeded in advancing its Queen's Pawn against the opposing center-Pawn, and White cannot avoid the exchange. To advance to e5 would be against the principle that no Pawn-move should be made in the opening which is not absolutely necessary. How easily (8) P-e5 could get White into trouble can be seen from the following variation: (8) ..., Kt-g4; (9) o-o, o-o; (10) Pf4 ??, B-c5+; (11) K-h1, Q-h4; (12) P-h3, Q-g3; (13) Pxg4, Q-h4 mate.
