Two Knights Defence: Classical Variation
[edit | edit source]5. O-O
[edit | edit source]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
