Stated plan

Play Rd1-e1, attacking the queen on e6 and setting up Ra1 to recapture favorably if the queen takes.

Reasoning

The queen on e6 is only defended by the king; moving Rd1–e1 attacks it along the open e-file. If Qxe1, then Ra1xe1 wins the queen for a rook, a great trade. If the queen moves away, White's back rank rook can grab the d7 rook next, since Rd1 vacated d1 but Ra1 covers e1 recapture and Qc8/Rd1 pressure remains strong. This is a clean tactical shot exploiting the open e-file.
