Queens Gambit Declined Cambridge Springs Defense Puzzle (Rated 1022): Win with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a crushing fork that forces a decisive material gain. White’s active knight and queen work together to overload the defender and exploit the exposed king. The key idea is that a forcing check can simultaneously attack multiple high-value targets, leaving Black unable to meet every threat. In positions like this, tactical accuracy matters more than long-term strategy: the best move wins by creating an immediate, unavoidable problem.
