Mate In 5 Or More Puzzle (Rated 1155): Spot a Mating Net — Checkmate with Bishop and Knight

This classical chess middlegame puzzle is built around a forcing tactical sequence that turns a small material edge into a direct attack on the king. The key idea is not quiet improvement, but a tactical refutation that uses a fork, discovered check, and clearance to open lines around the enemy king. Once the defender is dragged away, the remaining pieces coordinate to create a mating net. In positions like this, king safety matters more than material count.
