Lajos Portisch (Black) Puzzle: Capture — Pin

A pin becomes especially powerful when the pinned piece is also a valuable or vulnerable target. In this position, Black combines queen activity with pressure against the exposed king, turning a pinned pawn into a tactical entry point. The resulting sequence attacks several loose pieces and shifts the material balance decisively. The key idea is not simply to capture, but to use check and threats to prevent the opponent from stabilizing.
