How the Two Knights Defence: Nxf7 Sacrifice #3 works
The Two Knights Defence: Nxf7 Sacrifice #3 is a classic chess opening trap arising from the Two Knights 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.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Kxf7 7.Qf3+ Ke6 8.Nc3. 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 (Bill Wall (Introduction to Two Knights)). Recognising it early lets you either spring it as Black or sidestep it as White.
