Learn How to Fork: Decisive Material Gain
This middlegame puzzle comes from the Philidor Defense, Lion Variation, where active piece placement creates a tactical shot against an exposed king and loose defenders. White’s knight invasion is the key: it jumps into a checking square that also attacks major pieces, turning a simple check into a crushing fork. The position rewards players who notice hanging pieces, overloaded defenders, and the value of forcing moves before the opponent can coordinate.
