6.Bc4 seems to do the most.
King's gambit move 6 - what should white play?
If we play 6. Bc4 then we will surely face 6... d5!!
How do we respond to that?
7. exd5

5. Ne5 is already showing you don't have the guts to play a real King's Gambit. I would have played 5. Bc4 and moved into the Muzio lines.

7.ed5. White now has 1 center pawn, and black has none.

That's not the Muzio, since white has played h4 not 0-0. It's just a game losing blunder.

Ah, right, forgot about h4 since I never play it.

Morphy took Andersson to school in this line: http://www.chessgames.com/perl/chessgame?gid=1019060
You've just played the king's gambit. Your opponent is defiantly fighting to hold on to the extra pawn. What do you do?
It looks like things could get really messy soon, so choose carefully!
