Zukertort Opening Beginner Puzzle (Rated 1290): Win Material — Tactical Refutation

This puzzle comes from the Zukertort Opening, Old Indian Attack structure, where activity matters more than raw material count. White is behind in material, but the position contains a forcing tactical idea that turns the game around by exploiting loose pieces and the exposed black king. The key lesson is that in the opening, a single active piece can create a decisive material gain when it attacks multiple targets at once and removes the defender of a critical square.
