Openings Against D4 Puzzle (Rated 1335): Win — Qh4 Tactic
In this King's Indian Defense middlegame, Black uses superior king-zone pressure to exploit White's exposed king and overloaded pieces. The key strategic idea is to prioritize forcing threats over immediately recovering material. When a bishop is attacked but the opponent's king has weakened squares, a queen invasion can create tactical coordination and force a favorable simplification. This is a classic example of how king safety and piece activity can outweigh a temporary material deficit.
