Learn How to Win a Fork: Decisive Material Gain
This puzzle shows a classic tactical refutation built around a forcing knight jump that creates a fork on the enemy queen and rook. The key idea is not just winning a piece, but using king safety and piece activity to keep the opponent tied down. Once the fork lands, the follow-up forces the defender into a passive response, and the trapped piece becomes impossible to save cleanly. It is a strong example of a decisive material gain in the middlegame.
