Gambit

From Conservapedia

A gambit is the sacrifice of one thing in order to obtain something else, in a calculated risk.

As applied to chess, it refers to losing material, usually a pawn or two, in order to obtain a strategic advantage. (There are some exceptions, such as the Muzio Gambit, which sacrifices an entire knight.)

A gambit is also a small tool used to attach a cantle to a sporran.

Mike Gambit was a character in mid-70s Brtish action series 'The New Avengers', played by coffee salesman Gareth Hunt (d.2007).

Gambit was also one of the X-Men.
