Trapped Piece Advanced Puzzle (Rated 1236): Trap a Piece — Win

A trapped-piece tactic arises when an enemy piece has too few safe squares and every retreat concedes material. Here, White uses a passed pawn and active pieces to restrict Black’s bishop while exploiting weaknesses around the center. The key idea is not simply to attack a piece once, but to calculate whether its available escapes are safe. When a valuable bishop becomes tied to defensive duties, a forcing pawn advance can turn positional pressure into a decisive material gain.
