I do not like black after 7 .. e5, I think in that position white has already some advantage. Because it becomes difficult for black to develop. A nice illustration is the following game:

Kuligowski,Adam (2385) - Dybowski,Jerzy (2345) [A81] Naleczow masters Naleczow (8), 1986
1.d4 f5 2.Nf3 Nf6 3.g3 g6 4.b3 Bg7 5.Bb2 d6 6.Bg2 0-0 7.0-0 e5 8.dxe5 Ng4 9.Na3!? Nxe5 10.Nxe5 dxe5 11.Qxd8 Rxd8 12.Rad1 Re8 13.Nb5 Na6 14.Bd5+ Kh8 15.Bf7 Rf8 16.Ba3 c5 [16...Rxf7!? 17.Rd8+‚] 17.Bc4 Blacks problem is how to develop the queen-side. 17...e4 18.f3 exf3 19.exf3 f4 20.g4 b6 21.c3 Bb7 22.Nd6 b5 23.Bxb5 Nc7 24.Bc4 Ba6 25.Bxc5 Bxc3 26.Ne4 Bg7 27.Bxf8 Bxf8 28.Rd7 Bxc4 29.bxc4 Ne6 30.Rb1 1-0

Please read also page 61 of his english edition, where he gives a broader analysis of this game. Instead of 12 .. Nh5 he also gives Bg4 as interesting and he gives some analysis of 14 Ne2. I briefly looked at 13 Ne2 and my conclussion was that black probably does not have sufficient compensation for the pawn.  Fritz (8) is not a lot of help, since it does not look at moves for black, such as c6, which is needed in most lines for black.
