Yusupov Rubinstein System Other Variations Puzzle (Rated 948): Exploit Discovered Attack — Decisive Material Gain
This middlegame puzzle shows how a discovered attack can turn king safety into a decisive material win. Black’s active bishop and queen work together to overload White’s defenses, while White’s king is exposed and key pieces are tied down. The position is a classic example of tactical pressure converting into a forced sequence: first create a direct check, then use the exposed king to win a major piece. The lesson is that active pieces near the enemy king often outweigh small material deficits.
