Learn How to Fork: Decisive Material Gain
This puzzle shows a classic tactical fork in the Rat Defense, where Black’s knight jumps into the enemy camp and creates a forcing sequence. The key idea is that one piece can attack multiple targets at once while also giving check, which makes the defender’s reply extremely limited. In practical classical chess, these motifs often appear when the king is exposed and the opponent’s pieces are awkwardly placed, allowing a short winning combination rather than a long strategic squeeze.
