Learn How to Trap a Piece: Decisive Material Gain
This middlegame puzzle is all about creating a decisive material gain by restricting a key enemy piece until it has no useful squares. White uses a pawn advance to gain space, open lines, and force the opponent’s queen into a passive role. The position rewards patience: the best move is not a direct attack on the king, but a forcing sequence that improves White’s coordination while limiting Black’s counterplay. It is a classic example of how a trapped piece can decide a classical chess game.
