Rook Endgame Puzzle (Rated 963): Win With Discovered Check — Rook Endgame

This chess endgame is a classic example of using a discovered check to force the enemy king into a losing route while your rook stays active. The key idea is that tactical threats can outweigh material, especially when a passed pawn and an exposed king create a mating net. In classical chess, rook activity often decides the result more than extra pawns, and here the defender’s rook is vulnerable to a decisive tactical sequence.
