===4.Nxc3===
==== Scheveningen Formation ====
* Classical Main line: 4...Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Nf6 8.Qe2 Be7 9.Rd1 e5 10.h3 or 10.Be3
* Scheveningen setup: 4...Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Nf6 (or Be7) 8.Qe2 a6 9.Rd1 Qc7 (probably inferior Qa5) 10.Bf4 (10.Bg5) Be7
* Siberian Variation: 4...Nc6 5.Nf3 e6 6.Bc4 Nf6 and 7...Qc7, with the idea being after 7.0-0 Qc7 8.Qe2 Ng4!, 9.h3?? loses to the famous "[[Sicilian Defence, Smith–Morra Gambit, Siberian Trap|Siberian Trap]]" 9...Nd4!, winning the queen. If instead White plays 9.Rd1, preventing 9...Nd4, Black can continue with 9...Bc5 with a clearly better game.
