Indian Defense Pawn Push Variation Mate In 1 Beginner Puzzle (Rated 1021): Spot Mate in 1 — Back Rank Mate

This puzzle is a classic mate in 1 pattern where the defending king is boxed in by its own pieces and pawns. In middlegame positions like this, the key idea is to look for a direct forcing move that attacks the king immediately rather than winning material slowly. Even when the board looks active and both sides have threats, a single tactical shot can end the game if the escape squares are covered and the king has no flight square.
