Budapest Gambit
From Conservapedia
The Budapest Gambit is a rarely used gambit by the black pieces in chess where black moves its pawn to e5 for capture by a white pawn that sits at d4. The opening goes like this:
1. d4 Nf6
2. c4 e5
This gambit by black gives white more options than other gambits do. The common white response is to simply give up its pawn advantage after the gambit and build up its position with other pieces.[1]
