Two Knights Defence:Classical VariationEdit

5. O-OEdit

The classical variation. Castling both gives the White King some security and activates the rook to be able to come to e1 which has much potential to support the White e-pawn or pin any pieces that take the e-pawn. Black's possible sensible replies are:

  • 5....Nxe4
  • 5....Bc5
  • 5....d6
  • 5....Be7
