How the Budapest Defence: Wins a Piece works
The Budapest Defence: Wins a Piece is a classic chess opening trap arising from the Budapest Defence. In this line Black wins decisive material by move 8, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.c4 e5 3.d5 Bc5 4.Bg5 Ne4 5.Be3 Bxe3 6.fxe3 Qh4+ 7.g3 Nxg3 8.hxg3 Qxh1. 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 (Wacker - Klein, Eisenberg 1993). Recognising it early lets you either spring it as Black or sidestep it as White.
