How the B2:Pawn with Poison works
The B2:Pawn with Poison is a classic chess opening trap arising from the Pirc Defence. In this line Black wins decisive material by move 14, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 d6 2.d4 Nf6 3.Nc3 c6 4.f4 Qa5 5.Bd3 e5 6.Nf3 Bg4 7.Be3 exf4 8.Bxf4 Qb6 9.Na4 Qa5+ 10.Nc3 Qb4 11.a3 Qxb2 12.Na4 Bxf3 13.gxf3 Qxd4 14.c3. 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 (50 Opening Traps,Part 1 - B2:Pawn with Poison - B07 - https://lichess.org/@/CHESSLUCAFD). Recognising it early lets you either spring it as Black or sidestep it as White.
