Learn How to Win Material: Long Skewer
This chess endgame puzzle is all about a long skewer: a forcing line where a valuable piece is driven into a worse square, exposing something behind it. In simplified positions, rook activity and king placement often decide the game more than raw material count. Here, the attacking side uses checks to improve the rook’s position and keep the enemy king tied down, while a loose rook and weak pawn become tactical targets. The result is a decisive material gain rather than a mating attack.
