Stated plan
Play Qb8+ to force the king off the back rank, then pick off the a7 pawn and a6 bishop while keeping the black king exposed.
Resolves to b2b8 · −1408cp
Reasoning
The black king on d8 is boxed in by its own pawns on c7/d7, giving White a strong tactical shot. Qb2-b8+ delivers check along the 8th rank (c8 is empty). The king cannot block and must step to e7 or e8, after which Qxa7 hits the a6 bishop with no good defense (e.g. ...Bb7 walks into Qxb7, simply winning material), and White's attack against the exposed king continues with tempo.
