1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5 Nxe4 6.Bc4 Be7 7.Qe2 This move, often forgotten by manuals, offers good attacking chances in a less explored field. However, Black can avoid it at all, with transposition, initially refusing the gambit and then grabbing the pawn only after White has castled: 5 ... Be7 00 6.Bc4 7:00 Nxe4. 7...f5?! A natural move often played by Black for similarity with the classical variation of the Belgrade Gambit Accepted: 6.De2 f5. Here, however, White stands much better because the Queen does not obstruct the Bishop that is already in c4. 

[The best defence is: 7...Nc5 followed by 8.Bg5 Ne6 9.Nxe7 Nxe7 10.Bxe6 dxe6 11.0-0-0 c5 12.Qb5+ Key position of such variation 12...Qd7 (or 12...Bd7 ) 13.Qxc5 f6 14.Be3 e5 15.Bxd4 b6 16.Qa3 Qb7 17.Bxe5 fxe5 18.Nxe5 Be6 19.Rd6 Qc8 20.Qa4+ b5 21.Qxb5+ Kf8 22.Rhd1 h5 23.Qa5 Ke8 24.Qa4+ Kf8 25.Qe4 1-0 Toscano,J (2300)-Petters,O (2233) 2001;
