2... d6 – Black covers e5 and opens a path for the c8 bishop.
3. d4 – White opens the centre to use the lead in development.

4. Nxd4 – White takes back with the knight, which now stands in the centre.
4... Nf6 – Black develops with an attack on e4, so White must defend it.
5. Nc3 – White guards e4 and develops another piece.
5... Nc6 – The Classical Variation. The knight develops and challenges the d4 knight.
6. Bg5 – The Richter-Rauzer. The bishop eyes the f6 knight. White wants the queen on d2 and long castling.
6... e6 – The usual answer. The pawn covers d5 and opens a path for the f8 bishop.
7. Qd2 – The queen joins the bishop and clears the way for long castling.
7... a6 – Black takes b5 away from White's knight and bishop. The b-pawn is now ready to advance.
8. O-O-O – White castles long. The kings will stand on different wings, so both sides race to attack.
