Stated plan
Deliver check with the queen to drive the white king into a mating net exploiting the knight on b3.
Reasoning
Black's queen can deliver a strong check: Qe4-e1+. The white king on d1 cannot go to c1 (covered by the knight on b3) or to c2/d2/e2/e1 area covered by the queen, forcing Kc2 as the only legal reply. This starts a forcing sequence (Nb3-d4+ next, driving the king into the open and creating a decisive attack), which is clearly the strongest continuation available.
