Stated plan
Centralize the queen to f4, creating an unstoppable battery with the rook on f5 against f2/f1 and tying White's pieces down defensively.
Reasoning
Black's queen is quite restricted by its own pawns, but c7-d6-e5-f4 diagonal is open. Playing Qf4 centralizes the queen, eyeing f2, and combines with the rook already on f5 to create a real battery against f2/f1. Because the rook on f5 controls the f-file behind the queen, if White ever allows ...Qxf2+, the king cannot recapture (it would walk into the rook's line), forcing the king to e1 and winning the pawn with continuing attack (bishop h2 covers g1, restricting the king further). White's only real defense is to block with Be2-f3, but that costs time and loosens White's position while Black keeps strong pressure with rook, knight and bishop all aimed at the king. This gives Black a powerful initiative for no material cost.
