Accelerated Steinitz Gambit

The Steinitz Gambit usually occurs in the Vienna Opening, after 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.d4!? Qh4+ 5.Ke2 It is correctly named, as Steinitz played this line on plenty of occasions, although not always with plenty of success.
There is a line of the King's Gambit, also named the Steinitz Gambit, which is the same line as above, but with the knight moves removed (1.e4 e5 2.f4 exf4 3.d4?! Qh4+). This was the line I witnessed at a junior event today, although White went wrong with 4.g3?  Black missed the obvious win of a piece after 4 ... fxg3 5.Bg2 gxh2+ 6.Kf1 Qf6? and White eventually won after finding a nice forced mate which involved a queen sacrifice. But as the game was too 'up and down' to show the full power of the opening, I've chosen a different game instead.
