what should black do if Scandinavian defense not accepted ?


oh you hate that too? huh?
i've tried both the ...Bf5 line recommended by a lousy old 90s book that refused to give theory other than a couple lines and say "no problem for black" when a pawn on e5 (even as white, because it's in my way!) is intolerable. I want to play Nf6!!!!! I don't want to have to wiggle around pawns!
O.K. I removed them from my trainer because I want to STOP playing the scandinavian myself, but I have a book (I don't know how complete it is) for the 2...c5 sicilian advance variation you can study, but it's a move order pain to try and learn.
i'll upload the theory and share it here.
1.e4 d5 2.e5 Scandinavian Advance Theory
I broke the theory up into 6 lines I just put in 1 folder for sharing
1.e4 d5 2.e5 c5
3.f4 Nc6 4.Nf3 Bg4 - line 1
3.d4
_____3...Bg4 4.Be2 - line 2
_____3...cxd4 4.Qxd4 Nc6 is another possibility
3.Nf3 Be2 (3...Bg4 is another possibility)
_____4.h3 - line 3a
_____4.Bb5+ - line 3b
_____4.c3 - line 4a
_____4.d4 - line 4b
3.c3 Nc6
_____4.d4 Qb6 5.Nf3 cxd4 6.cxd4 Bg4 - line 5a
_____4.Nf3 Bg4 - line 5b
_____4.Bb5 Qb6!? 5.Bxc6+ Qxc6 - line 6a
_____4.f4 Bf5 - line 6b
what should black do if white just pushes e4 pawn forward instead of taking in Scandinavian defense
