effectually to develope his superior Pieces. There are several gambits,
but the most important, and one which includes many others, is the
King's gambit, commenced as follows:--

WHITE. BLACK.
1. K. P. to K's 4th. 1. K. P. to K's 4th.
2. K. B. P. to B's 4th. 2. P. takes K. B. P.

The Pawn offered by the first player here at his second move is called
the Gambit Pawn, and when taken by the adversary the opening becomes a
gambit.

The varieties of the gambits are often designated by the names of the
players who invented or first brought them into vogue--as the _Muzio_
gambit, the _Salvio_ gambit, the _Allgaier_ gambit, the _Lopez_ gambit;
while others obtain their names from the opening moves of the first
player, as the King's Bishop's gambit, which begins thus:--

WHITE. BLACK.
1. K. P. to K's 4th. 1. K. P. to K's 4th.
2. K. B. P. to B's 4th. 2. P. takes P.
3. K. B. to Q. B's 4th.

and is so called because the K's Bishop is played out at the 3d move
instead of the K's Knight.

There is also the Queen's gambit, of which the opening moves are--

WHITE. BLACK.
1. Q. P. to Q's 4th. 1. Q. P. to Q's 4th.
