Learn How to Win a Chess Endgame: Rook Skewer
This chess endgame is a classic example of how active rooks can decide a materially balanced or even slightly worse position. The key idea is a skewer: a forcing rook check that drives the king onto a vulnerable square and exposes a more valuable target behind it. In rook endgames, checks are rarely random—they are often used to improve piece activity, win pawns, and create a decisive material swing while the enemy king is cut off.
