French Defense Knight Variation Puzzle (Rated 861): Win with a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of a tactical fork that turns active piece placement into a decisive material gain. Black’s knight jumps into the heart of the position with check, forcing the king to respond while also attacking a valuable target. The key idea is that one move creates two threats at once: a forcing check and a direct attack on a loose piece. In practical classical chess, these motifs often outweigh static material because the opponent’s pieces are overloaded and coordination breaks down.
