Andrew Tang (Black) Puzzle: Attack — Pinned Piece

Attacking a pinned piece is a powerful chess endgame technique. A pinned defender may appear protected, but its restricted movement can make it vulnerable to a forcing capture, exchange sequence, or tactical overload. In this position, Black exploits the fact that a pawn is absolutely pinned to the king while coordinating two active rooks. The key idea is to use checks and exchanges to remove the pinned unit, seize the second rank, and convert superior piece activity into a decisive advantage.
