How the King's Pawn Opening: Bxf7 Sacrifice & Mate (Arnason–Pribyl) works
The King's Pawn Opening: Bxf7 Sacrifice & Mate (Arnason–Pribyl) is a classic chess opening trap arising from the King's pawn opening. In this line White delivers checkmate on move 7, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 d6 2.d4 g6 3.Nf3 Bg7 4.Bc4 Nd7 5.Bxf7+ Kxf7 6.Ng5+ Kf6 7.Qf3#. Each move looks reasonable, which is exactly why the trap is so effective over the board — Black walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Arnason - Pribyl, Latvia 1990). Recognising it early lets you either spring it as White or sidestep it as Black.
