How the Trap 4 #2 works
The Trap 4 #2 is a classic chess opening trap arising from the Vienna Game. In this line White delivers checkmate on move 10, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 e5 2.Nc3 Nf6 3.Nf3 Nc6 4.Bc4 Bc5 5.d3 O-O 6.Ng5 h6 7.h4 hxg5 8.hxg5 Nh7 9.Qh5 g6 10.Qxh7#. 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 (Chess Traps - Trap 4 - C50 - https://lichess.org/@/Aras_Acikkol11). Recognising it early lets you either spring it as White or sidestep it as Black.
