Leningrad Variation Puzzle (Rated 1756): Spot a Fork — Mate Threat
This middlegame puzzle is built around a classic mate threat combined with a fork. Black’s active knight jumps into the center with tempo, attacking the king and creating immediate tactical pressure on a key defender. The position shows why king safety matters so much when pieces are loose and the king is stuck in the center. Even though White is materially ahead, activity and coordination decide the game here.
