Learn How to Win a Fork: Decisive Material Gain
This puzzle is a classic middlegame tactical refutation where a forcing queen sacrifice opens the way for a knight fork and a decisive material gain. The key idea is that the opponent’s king and major pieces are vulnerable to a sequence of checks and captures, so the best move is not a quiet improving move but a forcing one. Once the first defender is removed, the follow-up tactic wins material by exploiting overloaded pieces and weak coordination.
