Two Knights Defence

[edit | edit source]

4...Nxe4?

[edit | edit source]

Not the best move for Black. Ignoring the threat of White's position, they grab the e-pawn. This initially seems like a good move because Black has 5...d5 after 5. Nxe4? forking the knight and bishop.

However, White can now capture Black's unprotected f-pawn with check: 5. Bxf7+ Ke7 6. d4! and Black cannot yet take on g5 without losing his queen.

5. Nxf7 is a mistake, as after 5... Qh4 Black gains an advantage even against White's best defense.
