Learn How to Win a Chess Endgame: Long Skewer
This chess endgame puzzle is built around a long skewer: a forcing rook check that drives the king onto a vulnerable square, then keeps the pressure on the same line to win material. In classical chess, these motifs often appear when active rooks and an exposed king outweigh raw pawn count. Here, the key is to notice that the enemy king cannot safely escape the file pressure, so every tempo matters and the defender is forced into a losing sequence.
