Slav Defense Steiner Variation Puzzle (Rated 1192): Win Material — Crushing Middlegame Tactic

This puzzle is a classic middlegame example of tactical simplification: one side can force a sequence that wins material by exploiting a loose queen and overloaded pieces. The key idea is to notice when a high-value piece is attacked while a capture also opens a line for a rook, creating a skewer-like effect. In positions like this, the strongest move is often not a flashy attack on the king, but a clean exchange sequence that leaves one side with a decisive material edge.
