gambit

(gămˈbĭt)

noun

1. An opening in chess in which a minor piece, or pieces, usually a pawn, is offered in exchange for a favorable position.
2. A maneuver, stratagem, or ploy, especially one used at an initial stage.
3. A remark intended to open a conversation.

Usage Note: Critics familiar with the nature of chess gambits have sometimes maintained that the word should not be used in an extended sense except to refer to maneuvers that involve a tactical sacrifice or loss for some advantage. But gambit is well established in the general sense of “maneuver” and in the related sense of “a remark intended to open a conversation,” which usually carries no implication of sacrifice.
