Learn How to Spot Mate in 1: Queenside Attack
This puzzle is a classic mate in 1 built around a queenside attack and a vulnerable king. The key idea is that the attacking queen can exploit the open lines and overloaded defenders around the enemy king. Even when the position looks balanced materially, king safety can outweigh everything else. In classical chess, these one-move finishes often come from a hidden mating net rather than a long combination.
