Petrov Defence

[edit | edit source]

3. Nxe5

[edit | edit source]

Black has to drive the white knight away before attacking.

  • The natural move 3...Nxe4 is a bad move, containing a deadly trap and variations that put White into a superior position. After White plays 4. Qe2, Black loses a pawn after 4... d5, d6, or f5 and 4... Nf6?? is a blunder that loses a queen. 4... Qe7 is the best move after which Black will likely win back the pawn, but White retains a stable advantage larger than the main line.
  • 3...d6 is the main line.
  • 3...Nc6 the Stafford Gambit
