How the Sicilian Defence: Mate in 6 (Larsen–Unknown) works
The Sicilian Defence: Mate in 6 (Larsen–Unknown) is a classic chess opening trap arising from the Sicilian Defence. In this line White delivers checkmate on move 6, punishing a natural-looking but losing idea from Black.
The full sequence runs 1.e4 c5 2.Nf3 f6 3.d4 cxd4 4.Nxd4 e5 5.Nf5 Ne7 6.Nd6#. 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 (Larsen - Unknown, Eindhoven 1982). Recognising it early lets you either spring it as White or sidestep it as Black.
