Learn How to Win a Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical fork that turns activity into material gain. One side’s pieces are coordinated around a vulnerable king and loose defenders, so a forcing check creates immediate problems. The key idea is that the attacking knight does more than give check: it also creates a second threat against a valuable piece. In classical chess, these double attacks often decide the game because the defender cannot meet both dangers at once.
