Ruy Lopez Berlin Defense Kingside Attack Intermediate Puzzle (Rated 982): Spot Mate in 1 — Kingside Attack

This puzzle comes from a Ruy Lopez Berlin Defense middlegame where the attack is aimed directly at the king. The key idea is that a seemingly ordinary position can hide a forced mating pattern when the enemy king’s shelter is weakened and key defenders are overloaded or absent. In classical chess, these tactical shots often appear after development has finished and the pieces are already lined up on open lines and diagonals.
