hmm, seems weakening, I never play f3 unless absolutely necessary, that's where my knight likes to go!
Scandinavian Defense: A Possible Counter

a real chess "genius" wouldn't play 2. ... dxe?
Welllllll it is set to instant move, but it usually makes pretty good moves.
I like the fxe4; the way I try to play it is so that the pawn on f3 is taken; I use the 3rd. move to develop and the Knight takes on f3

if i were black -
2.f3!? e6 with the threat of being 3...dxe4 and if white insists on 4.fxe4?? Qh4+
I guess it is possible to tranpose into BDG with d4...
3. exd5 exd5, when the pawn on f3 simply looks out of place... just a thought...
1. e4...d5 2. f3
Idea: kind of like the Blackmar-Diemer Gambit
