Rook Endgame Puzzle (Rated 1407): Win a Chess Endgame — Rook Skewer

This chess endgame centers on a powerful rook tactic: the skewer. In simplified positions, rook activity often matters more than raw material, and forcing checks can drag the enemy king onto vulnerable squares. Here, the attacking side uses tempo-gaining rook moves to keep the king exposed while also targeting a loose piece behind it. The advanced passed pawn adds extra pressure, making the defense collapse quickly once the rook becomes active.
