Learn How to Spot a Mate in 1: Rook Endgame
This chess endgame puzzle is a classic example of a mating net created by rook activity and king restriction. Even with equal material, one active rook can completely dominate the board when the enemy king has no flight squares and the back rank is vulnerable. In classical chess, these positions reward precise calculation: a single forcing move can turn a balanced rook endgame into immediate checkmate. The key idea is to look for checks that also cut off escape squares.
