Learn How to Fork: Decisive Material Gain
This middlegame puzzle is all about tactical pressure against the king and queen. Black’s active knight creates a forcing check that also improves the attack on White’s queen, turning a material deficit into a winning combination. The key idea is that a forcing move can do more than one job at once: check the king, create a fork, and expose a hanging piece. In practical classical chess, these motifs often decide games immediately.
