Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a fork creating a decisive material gain. One active knight jumps into the enemy camp and attacks multiple high-value targets at once, forcing the opponent into a narrow defensive response. The key idea is that the tactical move is not just a check, but also a direct threat to win material immediately. In classical chess, these motifs often appear when pieces are loose and the king is exposed.
