Learn How to Fork: Decisive Material Gain
This puzzle shows a classic tactical fork in the Queen's Gambit Declined, where a knight jump creates immediate pressure on multiple targets at once. In opening positions like this, piece activity and outposts matter more than raw material, and a single forcing move can swing the evaluation sharply. The key idea is to use a check to gain tempo, then win material from a piece that has wandered too far and cannot be defended in time.
