Russian Game Millennium Attack Puzzle (Rated 1010): Win Material — Discovered Attack

This Russian Game middlegame shows a classic discovered attack idea: one piece moves with tempo, uncovering a stronger line for a bishop behind it. The position is tactical because White’s bishop and queen are tied to the center and kingside, while Black can exploit the loose coordination around c4 and d5. The key is to notice when a pinned or overloaded piece can be removed to open a direct attack on a valuable target.
