Learn How to Win a Fork: Tactical Refutation
This middlegame puzzle from the Alekhine Defense Four Pawns Attack shows how a single tactical idea can turn a sharp position into a winning material edge. White’s pieces are active, but Black’s last move has created a vulnerable target and a fork-based tactic appears on the board. The key lesson is that strong-looking activity can be punished when one piece is overloaded and the king’s position is under pressure. In classical chess, these tactical refutations often decide the game immediately.
