How the Vienna Game: Wins a Piece (Glasscoe–Wall) works
The Vienna Game: Wins a Piece (Glasscoe–Wall) is a classic chess opening trap arising from the Vienna Game. In this line Black wins decisive material by move 10, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1 Kf8 7.Nh3 Qd4 8.d3 Nf6 9.Qf3 Nxd5 10.c3. 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 (Glasscoe - Wall, Sunnyvale, CA 1985). Recognising it early lets you either spring it as Black or sidestep it as White.
