Learn How to Fork Mate: Mate in 4
This middlegame puzzle comes from a Queen's Pawn Game structure where White’s pieces are aimed at the black king and the g6 point. The key idea is a forcing tactical sequence that begins with a sacrifice on g6, opening lines and dragging the king into a vulnerable square. From there, White uses a knight jump to create a fork-like mating net, combining checks, piece coordination, and king restriction. It is a classic example of how activity can outweigh material in classical chess.
