1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nxe4 6.Bc4 Nc5 A minor variant whose idea is to transfer the Knight to e6 overdefending the d4 pawn. Black has also played other secondary moves: 

[6...Ne7 7.Ne5 Nd6 (or 7...Nxd5 8.Bxd5 Qe7 9.Bxf7+ Kd8 10.Qxd4 Qb4+ 11.Qxb4 Bxb4+ 12.c3 Bd6 13.Nd3 and White is slightly preferable) 8.Qf3! Nxd5 9.Bxd5 Qf6 (9...Qe7? 10.Kd1! c6 11.Re1 (11.Bb3 ) 11...cxd5 12.Qxd5 Qe6 13.Nf3 Be7 14.Rxe6 dxe6 15.Qxd4+/- ) 10.Qe2 Be7 11.h4! h6 12.Rh3! 0-0 13.g4 c6 14.g5 Qf5 15.Rf3 Qh7 (15...cxd5 16.Rxf5 Nxf5 17.gxh6+/- ) 16.g6 1-0 McGrew-Milat/ICC 1995; 

6...d6 7.0-0 White has the advantage. 7...Be7 8.Re1 f5 9.Nxd4 Ne5 10.Bd3?! (10.Bb3 ) 10...0-0 11.f3 Nxd3?! (11...Bh4 ) 12.Nxe7+ Qxe7 13.cxd3 Qf6 14.dxe4 fxe4 15.Rxe4 Qg6 16.Qe2 c5 17.Ne6 1-0 Ewin-Wagner/Braunfels 2000;

6...Nd6 Significant played games with such move doesn't seem to exist 7.Bf4 That's Schiller's advice to reach a better endgame (Instead Monson's proposal is 7.Bd3 Be7 8.0-0 0-0 9.Re1 playing for the attack) 7...Be7 8.Qe2 0-0 9.Nxe7+ Qxe7 10.Qxe7 Nxe7 11.Bxd6 cxd6 12.0-0-0+/=

6...Bc5 7.0-0 0-0 (7...Ne7 8.Re1 c6 9.Nxe7 Qxe7 10.Bxf7+ Qxf7 11.Rxe4+ Kd8 12.b4+/- ) 8.Re1 Nf6 (8...b5 9.Bb3 Nf6 10.Bg5 Kh8 11.Nd2 a5 12.Ne4 Bb4 13.Nexf6 Bxe1 14.Qh5 h6 15.Bxh6 Qxf6 16.Nxf6 1-0 McGrew-Ferret/ICC 1996) 9.Bg5+/- d6 10.Nd2 Bf5 11.Ne4 Bxe4 12.Rxe4 Ne5 13.Bxf6 gxf6 14.Qh5 Ng6 15.Rd1 Kh8 16.Rh4 Nxh4 17.Qxh4 Rg8 18.Nxf6 Rg7 19.Bd3 d5 20.Bxh7 Rg4 21.Qh6 Bf8 22.Qh5 Rg5 23.Qh4 Rg4 24.Qxg4 Bg7 25.Nh5 1-0 Lopez de Lerma Ruiz,J-Lubkov,V (2422)/ICCF Email 2001] 

7.Bg5! f6 If Black is already forced to play a so horrible move, it means that the variation is highly dubious.
