How the Two Knights Defence: Bxf2 Sacrifice works
The Two Knights Defence: Bxf2 Sacrifice is a classic chess opening trap arising from the Two Knights Defence. In this line Black wins decisive material by move 10, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Nxf7 Bxf2+ 6.Kxf2 Nxe4+ 7.Ke3 Qh4 8.Qf3 Nf6 9.Ke2 Qxc4+ 10.Kd1 Nd4. 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 (Jentzch - Nosotta, Postal 1956). Recognising it early lets you either spring it as Black or sidestep it as White.
