Rook Endgame Puzzle (Rated 1008): Check — Rook Check
This chess endgame demonstrates the power of a forcing rook check when your king is centralized and your opponent has extra material. White is materially behind, but the rook can become active on an open file and immediately challenge the opposing king. The check gains time, restricts the king’s choices, and creates tactical pressure against vulnerable pieces and pawns. In difficult endgames, active piece coordination can matter more than simply counting material.
