Gambit
chess opening in which a player sacrifices material with the hope of achieving a resulting advantageous position
A gambit is a chess opening involving a sacrifice, usually a pawn. The player, usually White, sacrifices (gives away) a pawn or more to develop faster and get an attack against the king. Gambits are also used to control the center of the chess board for better development of pieces. The player who plays the Gambit hopes for a development advantage against the opponent. There are a few gambits that require more valuable pieces for a better chance of winning. An example:

Benko Gambit change
In modern times gambits are usually not for direct attacks on the king. They aim at 'positional' advantages, such as freer play for the pieces. A well-known example is the Benko Gambit:

In return for his pawn, Black gets open lines for his bishops and his rook on a8.
