Slav Defense Discovered Attack Puzzle (Rated 1039): Win With Discovered Attack — Tactical Refutation

This middlegame puzzle is a classic example of a discovered attack combined with king safety pressure. One piece is overloaded, another is pinned, and the key tactical idea is to move a blocking piece so a stronger piece can strike a high-value target. The position rewards alert calculation: the best line wins material by exposing a vulnerable queen and exploiting the coordination of the attacking pieces. It is a strong example of how tactical motifs can outweigh static factors.
