Pins In Rook Endgames Puzzle: Pin — Rook Endgame
In a rook endgame, a passed pawn can become a powerful tactical weapon when it restricts the enemy king and ties down a defending piece. A pin is especially dangerous when the pinned rook stands between its king and an attacking rook. The defender may appear to have ways to capture the advanced pawn, but moving the pinned piece can expose the king. The key idea is to combine pawn promotion threats with rook activity on an open file.
