Stated plan
Force the queen recapture with Rxd8+, displacing Black's queen from b6 and setting up Nc5 to win a pawn.
Resolves to d7d8 · −743cp
Reasoning
White's rook on d7 can capture the rook on d8 with check. Crucially, Black cannot recapture with the bishop on g7 (it isn't on the right diagonal), and the king has no escape square along the back rank, so the only legal response is Qxd8. This forces the black queen away from b6, abandoning the defense of b7 and a6, after which White's knight can jump into c5 hitting both weak pawns and winning material while Black's queen is stuck passively on d8.
