Blocking Escape Squares Puzzle (Rated 1500): Mate in 3 — Block the Escape Square
This chess endgame shows a classic mate block-escape-square pattern. White’s rook and knight work together to restrict the black king, while the advanced passed pawn adds pressure and limits defensive resources. The key idea is not just checking the king, but first controlling the squares it needs for flight. In positions like this, a quiet-looking forcing move can be the start of a decisive tactical sequence that ends in checkmate rather than a simple material win.
