I am thinking of classical with 4 e5
1 e4 e6 2 d4 d5 3 Nc3 Nf6 4 e5 Nfd7 5 f4 c5 6 c3 Nc6 7 Be3 cxd4 8 Nxd4 Bc5 9 Qd2
with 6.Nf3 (instead of 6.c3) ... it is Boleslavsky line.
and covered in excellent book "How to play against 1.e4" McDonald 2008 I just read last month
in this book very good explanation for the alternate system 7...Be7!?
I have one lost game with White in variation with ooo against good player (G.Valin) and no experience as Black but I did valuable work in these systems
difficulty is the number of various systems White or Black can play: with oo or ooo for White ; with play on blockade square d4 or not ; early attack on b2 and so on
for you to start, I advice you 7...Be7 as given by McDonald or 6...Qb6!? (delaying Nc6) one Korschnoi idea.
5.f4 c5 6.Be3 Qb6 7.Nf3 (what else ? if 7.Na4? Qa5+ 8.c3 cxd4 -/+) Be7 (7...Nc6 is main line ; 7...a6 8.a3 or 8.Rb1 ; 7..Qxb2 is risky 8.a3 ; 7...a6 8.a3 Nc6 9.Be2 Qa7 ) 8.Na4 Qa5+ 9.c3 Nxd4 10.Nxd4! Nc6 11.b4 Qc7 12.Bd3 (12.Nb5 Qb8 13.Bd3 g5) Nxd4 13.Bxd4 a5 14.a3 Bh4+ 15.g3 Be7 16.oo oo=
Black has played his plan on the queenside and is in control of e5 (more difficult to play f5 for White)
