Learn How to Win Material: Tactical Refutation
This opening puzzle comes from the Indian Defense and shows how active piece play can outweigh static material. White is behind in material, but the position contains a forcing tactical idea based on piece activity, pressure on key central squares, and a vulnerable black queen-side structure. The key lesson is that in the middlegame, a well-placed knight can create multiple threats at once and turn a defensive-looking position into a winning one.
