How the Old Benoni Defence: Wins a Pawn (D. Gurevich–GNUSURF) works

The full sequence runs 1.d4 c5 2.d5 d6 3.e4 g6 4.Nc3 Bg7 5.Nf3 Na6 6.Be2 Nc7 7.O-O Nf6 8.Bf4 O-O 9.h3 b5 10.e5 dxe5 11.Nxe5 b4 12.Nc6 Qd7 13.Nb5 Ncxd5 14.Ne5 Qd8 15.Nc6 Qb6 16.Bf3 Bb7. 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 (D. Gurevich - GNUSURF, 1995). Recognising it early lets you either spring it as Black or sidestep it as White.
