How the Wins a Piece (Schoenau–Froka) works
The Wins a Piece (Schoenau–Froka) is a classic chess opening trap. In this line White wins decisive material by move 8, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.g4 d5 2.Bg2 e5 3.c4 Be6 4.Nc3 d4 5.Bxb7 dxc3 6.Bxa8 Bc5 7.Qa4+ Bd7 8.Qa5. 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 (Schoenau - Froka, 1988.??.??). Recognising it early lets you either spring it as White or sidestep it as Black.
