Stated plan

Play Qxd6 to win the pawn while forking the rook on e7.

Resolves to d5d6 · lost a forced mate

Reasoning

The queen can capture the d6 pawn while simultaneously attacking the rook on e7 along the d6-e7 diagonal. White must either move the rook (losing the pawn for free) or try Rxd7, but then Qxd7 recaptures, netting Black a rook and pawn for a bishop.
