Black's QB and to bring out his own, the pressure on Black's KP
is relieved permanently, and sooner or later Black will break
through on the Q file, as his QP is no longer needed at Q3 for
the support of the centre pawn.

A different pawn formation is the result if White enforces the
exchange of Black's centre pawn at once. This he can do by
playing P-Q4, e.g.:

2. P-KB4 B-B4 or 4. P-B3 Kt-KB3
3. Kt-KB3 P-Q3 5. P-Q4 PxQP
4. P-Q4 PxQP 6. PxP B-Kt3
5. KtxP

Here Black can get an early advantage by attacking White's KP,
taking possession of the K file after castling on the K side.

All things considered, the student should in my opinion decline
the gambit, as in doing so he can get an easy and satisfactory
development. The treatment of the "King's Gambit accepted," which
aims at holding the gambit pawn, is most difficult and leads
early in the game to such complications as none but an expert can
hope to master.

[Footnote: As an example of the difficult play which ensues when
Black defends the pawn in the King's Gambit, I give the latest
variation of an attack introduced by Professor I. L. Rice, and
called the "Rice Gambit":

1. P-K4, P-K4; 2. P-KB4, PxP; 3. Kt-KB3, P-KKt4; 4. P-KR4, P-Kt5;
