Queens Gambit Other Variations Puzzle (Rated 956): Win Material — Discovered Attack
This middlegame puzzle is built around a discovered attack against the white king and queen coordination. Black’s active bishop and queen work together to exploit the loosened kingside and the vulnerable f2 square. The key idea is that one forcing move can open a line, create a check, and simultaneously expose a high-value target behind it. In positions like this, king safety matters more than material balance, and tactical pressure can decide the game immediately.
