Stated plan

Advance the c-pawn to c2 to create an unstoppable promotion threat supported by the rook.

Resolves to c3c2 · −672cp

Reasoning

Black's c3 pawn is dangerous; pushing it to c2 threatens promotion, supported by the rook on c8, and the bishop on c1 cannot capture c2 (not on its diagonal).
