The opening I used in my youth: 1d4 d5 2.Nc3 Nf6 3.Bf4

W.R.T the gambit there are three logical responses:
Nxg4 (free pawn)
g5 (forcing the bishop to move)
h5 (Counter gambit, either way - you lose the pawn)
Personally though - wouldn't this allow better use of the bishop?
However as this opening is nameless - and it is a scotch type opening I crown this:
