How the Budapest Defence: Smothered Mate (Flament–Gedult) works
The Budapest Defence: Smothered Mate (Flament–Gedult) is a classic chess opening trap arising from the Budapest Defence. In this line Black delivers checkmate on move 9, punishing a natural-looking but losing idea from White.
The full sequence runs 1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Bf4 Nc6 5.Nf3 Bb4+ 6.Nbd2 Qe7 7.h3 Ngxe5 8.Nxe5 Nxe5 9.a3 Nd3#. 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 (Flament - Gedult, Paris 1970). Recognising it early lets you either spring it as Black or sidestep it as White.
