Learn How to Fork: Mate in 3
This middlegame puzzle is built around a forcing tactical sequence where a knight fork creates immediate threats against the enemy king and major pieces. The key idea is that checks can be used to drag the defender into a vulnerable square, allowing the attacking side to coordinate queen and minor piece pressure. When the king is boxed in, even a material edge can become irrelevant because every reply is forced and the mating net is already in place.
