Learn How to Win with a Pin: Crushing Endgame Tactic

This puzzle shows how a simple pin can become a decisive tactical weapon in the middlegame-to-endgame transition. White’s active rook and knight work together to restrict the enemy king and heavy pieces, creating a position where one tactical shot wins material immediately. The key idea is that pinned pieces often cannot defend themselves or move freely, so a seemingly solid setup can collapse once a forcing check appears.
