White To Move Puzzle (Rated 790): Spot Mate in 1 — King Safety

This middlegame puzzle is a classic king-safety finish: White’s heavy pieces are already active around the enemy king, and the final blow comes from a direct mating net. The key idea is that when the king’s shelter is weakened and key escape squares are controlled, even a single forcing move can end the game immediately. In classical chess, these patterns often appear after active rook and queen coordination creates a decisive tactical refutation.
