White offers a Pawn to induce Black to give up his center-Pawn,
hence the name "Queen's Gambit." If Black could actually hold the
Pawn he would be justified in accepting the Gambit unless it can
be demonstrated that White's advantage in development yields a
winning attack. However, White can easily regain the Gambit-Pawn,
and so there is absolutely no reason why Black should give up his
Pawn-center.

The way in which White regains his Pawn in the accepted Gambit is
this: (3) ..., Pxc4; (4) P-e3, P-b5; (5) P-a4, P-c6 (if Black
takes the Pawn a4, White captures the Pawn c4 and then regains
the a-Pawn. (5) ..., P-a6, cannot be played on account of Pxb5,
opening the a-file for White's Rook so that Black cannot retake
the Pawn). (6) P-b3, Pxb3; (7) Pxb5, Pxb5; (8) Bxb5+ and Qxb3.

Now White is far ahead in the development and in addition he has
an open file for his Queen's Rook in which the black Pawn is
bound to be lost in the long run. Moreover, Black has no
compensation for White's strong Pawn-center.

For this reason the Queen's Gambit is hardly ever accepted and
the following defense played instead:

(1) P-d4 P-d5
(2) Kt-f3 Kt-f6
(3) P-c4 P-e6
(4) Kt-c3

Black has now the choice between either advancing his c-Pawn
right away or first developing the pieces of his Queen's wing. In
