Learn How to Trap a Piece: Decisive Material Gain
This middlegame puzzle is about turning activity into a decisive material gain by trapping a loose piece. White’s position is already better materially, but the key idea is to improve coordination and use a forcing sequence that limits the opponent’s options. The tactical pattern combines a pin on the e-file with pressure against the king and a vulnerable defender, creating a classic trapped-piece scenario. In classical chess, these situations often decide the game without any direct mating attack.
