Learn How to Win Material: Trapped Piece
This Polish Opening middlegame shows a classic tactical idea: a piece becomes overloaded and trapped on the edge of the board. When one side has active bishops and a loose rook, the opponent can use forcing moves to win material and keep the initiative. The key is that the target piece has very few safe squares, while the attacking bishop also creates pressure on the king side and along the long diagonal. In positions like this, activity matters more than raw material.
