Learn How to Win Chess Endgame: Rook Endgame Refutation
This chess endgame puzzle is all about recognizing when a seemingly active rook is actually a tactical liability. In rook endgames, activity matters, but so does coordination with the king and pawn structure. Here, the side to move can exploit an undefended rook and force a simplification that transforms the position from defense into a winning king-and-pawn race. The key lesson is that endgame tactics often begin with material targets, not flashy checks.
