Stated plan

Sacrifice-like capture Bxf7+ exploiting the double attack on f7 to win material with check.

Resolves to b3f7 · −3cp

Reasoning

The bishop on b3 and knight on g5 both attack f7, which is defended only by the king. Playing Bxf7+ forces the king to move (it cannot capture since Ng5 covers f7), winning a pawn with a dominant bishop on f7 that remains defended by the knight.
