Lesson
White to move. Main line: 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. d3 Ne7 5. Nxe5 c6 6. Bc4 Qa5+ 7. Nc3 Qxe5
After 5.Nxe5?? c6 the b5-bishop must move, and 6.Bc4 Qa5+! wins the knight: the check comes with tempo, White blocks with 7.Nc3, and 7...Qxe5 collects the piece that can no longer be defended.
The trap is a lesson in not grabbing pawns while pieces are loose. When your opponent voluntarily undefends a pawn in the opening, ask what tactical resource they are counting on before you take.
White does better to decline the invitation. Quiet moves such as 5.O-O or 5.Nc3 keep a comfortable edge and leave Black’s knight awkwardly placed on e7 with nothing to show for it. Traps like this are played for the practical chance, not because the position deserves them.
