Learn How to Discover a Fork: Winning Material
This puzzle is a classic middlegame example of a discovered attack that turns into a powerful fork. White’s pieces look active and materially ahead, but the king’s position and loose coordination create a tactical opening for Black. The key idea is to move a piece with tempo so another piece suddenly attacks along a line, forcing the king to respond while a major piece is also hit. That combination wins material and shifts the evaluation sharply.
