Zukertort Opening Tennison Gambit Beginner Puzzle (Rated 1172): Discover Attack — Tactical Refutation

This middlegame puzzle shows how a single forcing move can turn an active piece into a tactical weapon. The key idea is a discovered attack: one piece moves with tempo, uncovering pressure on a more valuable target behind it. Here, the position is already sharp because the king is exposed and the pieces are lined up on open files and diagonals. When the opponent’s king safety is weak, forcing checks often decide the game by winning material or creating a decisive attack.
