Chess Opening Theory/1. g4/1...d5/2. Bg2/2...Bxg4

Grob's Gambit Accepted Black "accepts" the gambit by just taking a pawn. White usually continues with two moves: 3. c4 c4, the Fritz Gambit is another move where white gambits a pawn. However it's tricky - after dxc4 white can play Bxb7 and take the rook in future. But this is risky situation, because you don't really have a continuation after fourth move. 3. c3 This is more solid move. It doesn't create any attacks but helps to develop and play d4 in future in order to create a good pawn structure to complete development later. But don't forget that your kingside is damaged.
