Learn How to Spot a Fork: Zukertort Opening
This puzzle is a classic middlegame example of tactical punishment for loose pieces and an exposed king. In the Zukertort Opening, Black’s active knight jump creates a forcing check that also attacks a valuable rook, turning a normal-looking position into a winning sequence. The key idea is that checks, forks, and discovered threats often outweigh static material balance when the enemy king is stuck in the center.
