Learn How to Skewer: Exposed King Endgame
This chess endgame puzzle is a classic example of how active rooks can turn a material deficit into a winning attack. The key idea is an exposed king combined with a long skewer: one rook forces the king to move, then the line opens so the more valuable piece behind it becomes vulnerable. In practical classical chess, these patterns often decide games because king safety matters more than extra pawns when the pieces are active.
