Learn How to Trap a Piece: Decisive Material Gain
This middlegame puzzle is a classic example of a trapped piece turning into a tactical collapse. Black’s position looks active, but one overloaded bishop becomes vulnerable because it is tied to the king’s safety and cannot escape. In classical chess, these positions often reward precise calculation over general principles: a single forcing sequence can convert pressure into decisive material gain. The key idea is to notice when a piece is pinned, attacked, and short of squares at the same time.
