Sicilian Defence, Poisoned Pawn Variation
Moves:1.e4 c5 2.Nf3 d6 3.d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6.Bg5 e6 7.f4 Qb6 8.Qd2
White allows Black to take the pawn. Having played 7...Qb6, Black should take the pawn now with /8...Qxb2/. If Black radically changes plans and does not take the pawn, White will simply castle queenside (9. 0-0-0), protecting the pawn, and the Black queen will be out of place on b6, it would prefer to be on c7 where it doesn't obstruct the b-pawn.
