Stated plan
Play Qxh4+ to win material by force with a check that exploits White's weakened king shelter.
Resolves to d4h4 · −7cp
Reasoning
The black queen on d4 can capture the h4 pawn with check along the h-file, since h1 king has only the h-file open to it. This forces White to either block with Rg3-h3, Qc2-h2, or move the king to g1, exposing the g3 rook to a follow-up Qxg3+ winning material, or otherwise simply netting the h4 pawn with tempo. This is clearly the most forcing and profitable continuation.
