Queens Gambit Declined Three Knights Puzzle (Rated 904): Win Material — Fork Tactics
This middlegame puzzle shows a classic tactical refutation built around king safety and piece coordination. White’s active pieces create pressure on the black king, and the key idea is to use a forcing check to drag the defender away from the critical square. Once the king is exposed, the follow-up attack targets two valuable pieces at once, turning a small initiative into a decisive material gain. These are the kinds of patterns that appear often in classical chess and practical game review.
