How the Vienna Game: Wins a Pawn (Hauwert–Welling) works
The Vienna Game: Wins a Pawn (Hauwert–Welling) 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.g3 Bc5 4.Bg2 h5 5.Nf3 h4 6.Nxe5 Nxe5 7.d4 h3 8.Bxh3 Bxd4 9.Bg2 Bxc3+ 10.bxc3 d6. 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.
