Indian Defense Mate In 1 Intermediate Puzzle (Rated 879): Spot Mate in 1 — King Safety

This puzzle is a pure mate in 1, built around king safety and a direct mating net in the middlegame. The key idea is that the defending king has too few safe squares and the opponent’s pieces already control the escape routes. In positions like this, the strongest move is often not a material win but a forcing checkmate that ends the game immediately. Always scan for the most forcing checks first when the king is exposed.
