Stated plan

Capture the loose g7 pawn with the queen, forking the rook on h8.

Reasoning

The pawn on g7 is undefended (rook on h8 does not guard it diagonally), and the queen on c3 can capture it via the c3-g7 diagonal, simultaneously attacking the rook on h8. This wins material and forces further concessions from Black.
