Learn How to Win by Fork: Pin Sacrifice
This middlegame puzzle shows how a pinned piece can become the target of a forcing tactical sequence. White’s queen and king alignment creates a vulnerable line, while Black’s active minor pieces coordinate to exploit the exposed center. The key idea is attraction: one piece is lured onto a square where it becomes overloaded, allowing a fork and a decisive gain of material. In classical chess, these patterns often appear when development is uneven and the king remains in the center.
