Jose Raul Capablanca (White) Puzzle: Mate — Rook Net
A mating net is created when active pieces restrict the enemy king’s escape squares while keeping forcing threats alive. Here, White’s queen and rook already exert strong pressure around the black king, despite Black’s material advantage and dangerous passed pawns. The key is to value king safety above material: coordinated heavy pieces can turn a seemingly losing chess endgame into a forced attack when the opposing king has few safe squares.
