Learn How to Win Material: Fork Tactic
This middlegame puzzle is a classic example of a tactical refutation built around a fork and a trapped piece. Black’s active knight jumps into the position with check, forcing the king to move while simultaneously attacking multiple high-value targets. The key idea is that the checking move is not just a king move; it also creates a material win by exploiting loose coordination and an undefended rook. In practical classical chess, these motifs often decide games immediately.
