Zukertort Opening Sacrifice Puzzle (Rated 1294): Spot Mate in 2 — Kingside Attack

This middlegame puzzle is a classic example of a forcing kingside attack where tactical themes outweigh material. White’s active queen and knight coordinate against the black king’s shelter, and the position contains a direct tactical refutation of Black’s setup. The key idea is to use a forcing check that drags a defender away and opens a decisive line toward the king. In positions like this, king safety becomes the main factor, even when one side is up material.
