Learn How to Fork: Decisive Material Gain
This puzzle shows a classic opening tactic where an active knight creates a fork against the king and a rook, turning a small initiative into a decisive material gain. In the Nimzo-Larsen Attack, piece activity and king safety matter a lot, and here Black uses those factors to punish White’s loose development. The key idea is that a forcing check can drag the king into an awkward square and leave a major piece vulnerable to capture, which is a common pattern in classical chess.
