Hamppe-Muzio Gambit involves a pawn storm by black whereas white will lead in development and white sometimes may even sacrifice a piece for a lead in the attack. Having said that in order for it to be a success white needs to play the game actively accounting for the loss of a piece.

And Rf7 is a checkmate on the next move if Nf6 is not played.
In the Hamppe-Muzio Gambit and Hamppe-Allgair-Thoroid Gambit, white should be in a position to play a really aggressive chess and ready to sacrifice a piece and play the game worthy of the sacrificed piece. If the white player is a beginner or an intermediate player then this is not the opening rightfully recommended even for the blitz or bullet games
