Key ideas
- After 3...exd4 4.Nxd4, White has a free hand in the centre, and Black counterattacks with ...Bc5 or ...Nf6.
- Main lines lead to open, piece-play positions with less theory than the Ruy Lopez.
Plans for White
Use the open centre and the lead in development. Watch for Black's pressure on e4 and d4.
Plans for Black
Develop quickly with ...Nf6 and ...Bc5 and target White's central pieces.
