Learn How to Trap a Piece: Decisive Material Gain
This middlegame puzzle comes from the Sicilian Defense and shows a classic trapped piece idea. White’s attack is built around active pieces, king safety, and a vulnerable back-rank-style setup near the black king. The key motif is that one black piece becomes overloaded and cannot escape once the forcing sequence begins. These positions often look tactical, but the real lesson is strategic: when the enemy king is exposed and a major piece is poorly placed, forcing moves can convert pressure into decisive material gain.
