Semi Slav Defense Discovered Attack Puzzle (Rated 870): Win Material — Discovered Attack

This middlegame puzzle is built around a tactical refutation where one active piece is overloaded and another becomes vulnerable to a discovered attack. White’s rook activity on the e-file creates immediate pressure, and the key idea is to use forcing moves that remove the defender while exposing a higher-value target behind it. The position rewards calculation more than long-term strategy: once the tactical sequence starts, material falls quickly and the advantage becomes decisive.
