A strategic move…
A gambit is a strategic move, often in chess but also in politics or business, where a player sacrifices something up front for future gain.
The noun gambit comes from an Italian word, gambetto, which means “tripping up.” When you make an opening move, offer something, or start a conversation with something that seems self-sacrificing but is really a ploy for greater advantage in the long run, that’s a gambit. In chess, a gambit is when you sacrifice a pawn early for better positioning. When you offer to drive the morning carpool, that might be a gambit to get the afternoon shift off.
