Learn How to Fork: Decisive Material Gain
This puzzle comes from the Center Game and shows a classic middlegame tactical refutation built around a fork and a pinned piece. White’s queen and pieces have created pressure, but Black can turn the tables by using a forcing check that drags the king into an awkward square. The key idea is that the checked king cannot safely ignore the knight’s jump, because the follow-up wins material by attacking multiple loose targets at once. It is a strong example of how tactical activity can outweigh static material.
