How the Bishop's Opening: Opening Trap (Hejny–Jerabek) works
The Bishop's Opening: Opening Trap (Hejny–Jerabek) is a classic chess opening trap arising from the Bishop's opening. In this line Black wins decisive material by move 6, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.e5 d5 5.exd6 Bxd6 6.Qxd4 Bb4+. Each move looks reasonable, which is exactly why the trap is so effective over the board — White walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Hejny - Jerabek, Czechoslovakia 1993). Recognising it early lets you either spring it as Black or sidestep it as White.
