Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a fork leading to decisive material gain. White’s active knight jumps into the enemy camp with tempo, creating a check that also attacks a valuable piece. The key idea is that one move can do two jobs at once: force the king to respond and simultaneously win material. In practical classical chess, these tactical motifs often appear when the opponent’s king is slightly exposed and a major piece is poorly coordinated.
