How the The Bishop helps to win the Queen works
The The Bishop helps to win the Queen is a classic chess opening trap arising from the Ruy Lopez. In this line Black wins decisive material by move 9, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.Nf3 Nc6 3.Bb5 Bc5 4.O-O Nge7 5.c3 f5 6.d4 Bb6 7.d5 fxe4 8.Ng5 Nb8 9.Ne6. 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 (50 Opening Traps,Part 1 - The Bishop helps to win the Queen - C64 - https://lichess.org/@/CHESSLUCAFD). Recognising it early lets you either spring it as Black or sidestep it as White.
