Stated plan

Capture the undefended queen on c1 with the rook, winning material after the forced recapture sequence.

Reasoning

Black has two queens on c1 and c4 plus a knight on d3, but White's rook on b1 can capture the queen on c1 directly. After Rxc1 Nxc1 Rxc1, White nets a queen and knight for a single rook, a huge material win, while the remaining black queen on c4 has no immediate follow-up threat against White's king.
