How the Scandinavian Defence: Knight Fork #2 works
The Scandinavian Defence: Knight Fork #2 is a classic chess opening trap arising from the Scandinavian Defence. In this line Black wins decisive material by move 21, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 d5 2.f3 dxe4 3.fxe4 e5 4.d3 Nf6 5.Nf3 Nc6 6.Be2 Bc5 7.Nc3 O-O 8.Na4 Bb6 9.Nxb6 axb6 10.O-O Be6 11.a3 Nd4 12.Nxd4 Qxd4+ 13.Kh1 Ra4 14.c3 Qd7 15.b4 Rfa8 16.Qe1 Bg4 17.h3 Bxe2 18.Qxe2 c5 19.bxc5 bxc5 20.Rf3 Nh5 21.Rf5 Ng3+. 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 (Chess Trap - Faves4life (1853) - Cococh360 (1845) - B01 - https://lichess.org/@/Cococh360). Recognising it early lets you either spring it as Black or sidestep it as White.
