Rapport Jobava System Hanging Piece Beginner Puzzle (Rated 1389): Mate in 1 — Hanging Piece Tactic

This puzzle is a classic middlegame checkmate pattern where one active piece lands on a key square and the enemy king has no legal escape. The position rewards alertness to hanging pieces, king safety, and forcing moves. Even though material may be uneven, the decisive idea is not to win more material but to recognize that the opponent’s king is already boxed in by its own pieces and weak dark-square control. In classical chess, these tactical finishes often appear after a single overlooked weakness.
