Learn How to Win a Chess Endgame: Rook Skewer
This chess endgame puzzle shows how active rooks can decide the game even when material is level. The key idea is to use a forcing check to drag the enemy king onto a vulnerable square, then exploit the alignment of king and rook with a skewer. In rook endgames, activity matters more than pawn count, and a single tactical shot can convert a seemingly equal position into a winning one. Look for checks that also win a loose piece or create a discovered attack.
