5...Be7?

[edit | edit source]

The position after 1. e4 e5 2. Nf3 d6 3. d4 Nd7 4. Bc4 exd4 5. Nxd4 is a critical juncture for Black. The seemingly natural move 5...Be7? is a blunder, and 5...Ngf6 is a safer and superior alternative.

White can exploit the blunder with 6. Bxf7+!, intending to win the Black's queen with 7. Ne6 and 8. Nxd8+.

The move Bxf7+ is beneficial for several reasons:

  • It sets up the Ne6 threat, prevents the defense of e6 with fxe6, and captures the black pawn on f7.
  • The white knight on d4 can move to e6 to capture the black queen on d8.
  • The white knight threatens the black queen on d8.
  • White utilizes the a2-g8 diagonal to capture the black pawn on f7.
  • Additionally, White can consider playing Qd5, while Black can play g6 and use the 8th rank to control the square d8 with the rook on h8.
