Fork Puzzle (Rated 1116): Win with a Fork — Queen's Gambit Declined
This puzzle comes from a Queen's Gambit Declined middlegame where one active knight creates immediate tactical pressure by attacking multiple targets at once. The key idea is a fork: a single piece move can force the king into check while also winning material. In positions like this, the side with the initiative often converts a material edge by exploiting loose pieces, exposed king placement, and poor coordination rather than by a long attack.
