For the holonovel, please see Queen's Gambit.

The queen's gambit was a move in three-dimensional chess.

Commander William Riker used the queen's gambit coupled with an Aldabren Exchange to defeat the Ferengi Nibor at the game. The game occurred during the closing reception of the biennial Trade Agreements Conference aboard the USS Enterprise-D. (TNG: "Ménage à Troi")
