Early Divergences

Black can transpose to the Two Knights Defense on his third move by 1.e4 e5 2.Bc4 Nf6 3.d4 Nc6 4.Nf3, leaving room for several divergences from the Perreux Variation. The main alternatives to 4....exd4 are considered below:

These alternative lines are generally inferior, but 4....d6 (a variation of the Hungarian Defense) is worth some consideration as it can be difficult for White to convert his advantage to a win.

ED1) 4....Nxd4? (a blunder) 5.Bxf7+! Kxf7 6.Nxe5+ Ke6 7.Qxd4 and White has a winning advantage - See Analysis.

ED2) 4....Nxe4 5.dxe5

ED2b) 5....d6? 6.Qd5?! (Better and more forcing is 6.Bxf7+! Kxf7 7.Qd5+ followed by 8.Qxe4) 6....Be6 7.Qxe4 d5 8.Bxd5 Bxd5 9.Qe2 h6 10.Bf4 g5 11.Bg3 h5 12.h4 g4 13.Ng5 Bxg2 14.Rg1 Nd4 15.Qc4 Bb4+ 16.c3 Nc2+ 17.Ke2 Bd5 18.Qd3 Nxa1 19.Qb5+ c6 20.Qxb4 Nc2 21.Qa4 Na1 22.Nd2 b5 23.Qd1 Bc4+ 24.Ke1 Qd3 25.f3 Qe3+ 0-1 Tabakovic-Ek, Stockholm 1994.
