Nimzo Larsen Attack Hanging Piece Beginner Puzzle (Rated 1000): Spot Mate in 1 — Hanging Piece Tactics
This puzzle comes from the Nimzo-Larsen Attack and shows how a loose king can be punished immediately when the enemy queen is active near the king zone. The key idea is that a hanging piece can also be a mating piece if it sits on a critical square with no escape. In practical classical chess, these patterns often appear in the middlegame after development has lagged and king safety has collapsed.
