King in the middle (3)

by Oliver Reeh
10/9/2020 – Grabbing the opponent's b-pawn in the opening by sending your queen on a killing spree is not always bad, as the Poisoned Pawn Variation in the Najdorf (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qb6!?) shows. But in the diagram position, Black's greedy 9...Qxb2? is indeed bad. However, to refute the move, White needs to use many a piece. Have fun!

But in order to refute it, White will need to employ many a piece. Have fun! Qxb2? 9...Bc5 and 9...Nxd4 10.Bxd4 Bc5 are the theoretical main moves.
Black's queen has uprooted the Nc3. What now?
