Learn How to Deflect the King: Rook Endgame
This chess endgame puzzle is a classic example of using a rook to force the enemy king into a worse square and then win material by deflection. The key idea is not a direct checkmate, but a sequence of forcing checks that drag the king away from defending a critical piece. In classical chess, these positions often look balanced until one active rook creates a decisive tactical net. The side to move must calculate accurately because the winning idea depends on king activity, piece coordination, and timing.
