Zukertort Opening Mate In 3 Puzzle (Rated 1093): Spot — Mate in 3

This middlegame puzzle comes from the Zukertort Opening and shows how a seemingly material-rich position can hide a forced tactical refutation. The key idea is king safety: when the enemy king is stuck in the center and your queen can invade with tempo, the position can collapse quickly. Here, the attack is built around the f2/f7 complex, a classic target in classical chess and many sharp opening lines.
