The Fred Defence arises after 1.e4 f5. ECO code: B00.

Named as a humorous contrast to the "King's Gambit" (1.e4 e5 2.f4), the Fred Defence is an immediate gambit by Black. After 2.exf5, Black has sacrificed a pawn for dubious compensation. The position weakens the e8–h5 diagonal and the a2–g8 diagonal. White obtains a clear advantage with accurate play. The defence is considered objectively unsound.
