Zukertort Opening Tennison Gambit Mate In 1 Puzzle (Rated 1104): Spot Mate in 1 — Zukertort Opening

This puzzle comes from the Zukertort Opening, specifically the Tennison Gambit, and it shows how quickly an active queen can finish a game when the enemy king is exposed. In the opening, development and king safety matter more than material count, and here White’s pieces coordinate to create an immediate mating net. Even though Black is materially ahead, the position is tactically lost because the king has no safe squares and the checking move is decisive.
