Learn How to Trap a Piece: Middlegame Advantage
This middlegame puzzle shows how a seemingly active bishop can become a tactical liability when its escape squares disappear. White’s position is built around pressure on the kingside and a forcing pawn advance that opens lines at the right moment. The key idea is not a flashy sacrifice, but a practical winning combination that converts piece activity into material gain by exploiting a trapped piece and the opponent’s loose coordination.
