Stated plan

Play Rc1+ to force the king off the first rank, clearing the way for the e-pawn to promote with rook support.

Resolves to c3c1 · −0cp

Reasoning

Black's rook can deliver check along the first rank, and after the king moves the e3-pawn is ready to promote next with rook support on the first rank, since c1 already covers e1.
