Viacheslav Ragozin (White) Puzzle: Mate — Rook Mate

This chess endgame demonstrates how an active king and rook can convert a dangerous-looking position into a forced checkmate. Both sides have advanced passed pawns, creating a promotion race that demands precise calculation. The key strategic idea is to coordinate the king with rook checks while restricting the opposing king’s escape squares. Instead of rushing to promote, the attacking side uses the exposed king and the rook’s long-range control to build a mating net.
