Scotch Game Blumenfeld Attack Puzzle (Rated 1309): Win Material — Decisive Rook Sacrifice

This middlegame puzzle shows a classic tactical idea: using a rook sacrifice to break through a king that is stuck in the center. Even though White has extra material, the exposed king and loose coordination create a forcing sequence that wins back the initiative. The key is to notice how one active rook can overload the defender and drag the queen into a vulnerable exchange, turning a material deficit into a decisive tactical gain.
