Ruy Lopez Old Steinitz Defense Puzzle (Rated 1401): Win Material — Crushing Middlegame Tactic

This puzzle is a classic middlegame example of using active piece placement to force a major material win. White’s queen is centralized and creates tactical pressure against the black queen, knight, and rook coordination. The key idea is that a seemingly active enemy piece can become overloaded, allowing a forcing sequence that simplifies into a winning material edge. In positions like this, calculation matters more than long-term plans: look for forcing moves that exploit loose defenders and tactical alignment.
