Black remains with an isolated Queen's pawn after the exchanges which follow; but as in most forms of the Sicilian Defence, Black's Queen's pawn is weak, the position arising from Black's text-move is not inferior to any other he can obtain.

THE QUEEN'S GAMBIT.

The Queen's Gambit, 1. P to Q 4, P to Q 4; 2. P to Q B 4, P takes P; 3. P to K 3, or 3. P to K 4, or 3. Kt to K B 3, &c., is rarely played, because the Gambit pawn cannot, as in the King's Gambit, be defended by Black with the Knight's pawn; therefore the offered Gambit is usually declined (say, by 2. ... P to K 3), and the games take the form of close openings. The Queen's Gambit Declined is a very popular Opening in tournaments.

THE FIANCHETTO.[[105]]

The Fianchetto takes various form—viz., the King's Fianchetto, wherein White commences with 1. P to K Kt 3, and 2. B to Kt 2; and the Queen's Fianchetto, where White plays 1. P to Q Kt 3, and 2. B to Kt 2; the King's Fianchetto Defence, where Black defends with 1. ... P to K Kt 3, and 2. ... B to Kt 2; and the Queen's Fianchetto Defence, where Black defends with 1. ... P to Q Kt 3, and 2. ... B to Kt 2. The Double Fianchetto is where either White or Black develops both Bishops at Kt 2. The shape of White's development against either Fianchetto defence should be as under:

WHITE.BLACK.
1.P to K 41.P to K Kt 3
2.P to K B 42.P to K 3
3.P to Q 43.B to Kt 2
4.Kt to K B 34.P to Kt 3
5.P to B 35.B to Kt 2
6.B to Q 36.Kt to K 2
7.B to K 37.P to Q 4
8.P to K 58.Kt to Q 2
9.Q Kt to Q 2, &c.

All kindred Openings should be treated after this manner—viz., the opposing player should aim at the formation of a strong centre, so as to close the diagonal occupied by the Bishop.
