Corner Mate Puzzle (Rated 835): Spot Mate in 1 — Queen's Pawn Game Puzzle

This puzzle comes from a Queen's Pawn Game opening where development and king safety collide. White’s pieces are active, Black’s king is still stuck in the center, and the position contains a classic mating net. In these situations, the strongest move is often not a material grab but a forcing tactical finish. The key idea is to look for checks that exploit weak back-rank control, overloaded defenders, and squares around the enemy king that cannot be covered in time.
