3...f6?

edit

This move, seemingly attacking the knight, allows White to win with 4. Qh5+! because it allows 4...g6 5. Nxg6! hxg6 6. Qxh8 when White is up material. Other legal moves instead of 4...g6 would lead to checkmate:


  • 4...Ke7?? leads to:
   5. Qf7+! Kd6 6. Nc4+ Kc6 7. Qd5+ Kb5 8. Ne5+ Ka4 9. Qc4+ Bb4 10. Qb5#
  • 4...Kf8?? simply leads to a checkmate in one, with 5. Qf7#.
