Discovered Attack Puzzle (Rated 1309): Win with a Discovered Attack — Endgame Rook Trap
This chess endgame puzzle is built around a crushing discovered attack in a rook endgame. The key idea is that one forcing move creates a direct threat while also exposing a hidden line of attack against the opponent’s king and pieces. In simplified positions, active rooks and king activity often decide everything, so even a small tactical detail can become decisive. Here, the position rewards precise calculation, not material counting alone.
