Horwitz Defense Fork Puzzle (Rated 1129): Mate in 2 — Queen Sacrifice

This middlegame puzzle is a classic example of a forcing mating net built around king safety and piece coordination. White’s queen and knight are ideally placed to exploit the exposed black king, while Black’s loose kingside structure creates tactical targets. The key idea is that a forcing check can drag the king into a vulnerable square, where the follow-up delivers a direct mate. In classical chess, these short combinations often come from active pieces and weak dark squares.
