The idea

Both sides develop all four knights before committing a pawn, producing one of the most solid and symmetrical openings in chess.

Main line: 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 Bb4 5.O-O O-O 6.d3 d6

What White wants

  • Castle quickly and use the slight space edge
  • Prepare d4 with Re1 and Bxc6 or with careful piece play
  • Play for a small, safe plus rather than a sharp fight

What Black wants

  • Copy White's setup and hold the symmetry
  • Pin with ...Bb4 and trade pieces whenever possible
  • Keep the structure intact and aim for a comfortable draw

Key idea

Understand this and the moves stop needing to be memorised.

Symmetry is a weapon for the defender

Both sides have played their e-pawn forward and developed two knights, so neither has chosen a distinctive pawn structure yet. Symmetry makes development straightforward, but Black cannot copy blindly once White creates a threat. The d4 break and exchanges on c6 are ways to introduce imbalances.

Common mistake

Copying every move just because the position starts symmetrically. A central break or an exchange on c6 changes the balance of threats, and the player who ignores that change can lose time defending pieces that were safe a move earlier.
