How the Owen's Defence: Knight Fork works
The Owen's Defence: Knight Fork is a classic chess opening trap arising from the Owen's 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 b6 2.d4 Bb7 3.Nc3 e6 4.Bd3 Nf6 5.Nge2 d5 6.e5 Nfd7 7.Nf4 c5 8.Nxe6 Qe7 9.Nxd5 Bxd5 10.Nc7+. 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 (Bhend - Schneiders, 1985). Recognising it early lets you either spring it as Black or sidestep it as White.
