Learn How to Win Material: Fork Tactics
This middlegame puzzle is a classic example of using a forcing queen move to win material by attraction. The key idea is that the enemy king is exposed, so checks become especially powerful when they drag a defender onto a square that helps your follow-up. After the first forcing move, the position simplifies into a sequence where the king is pulled into the open and a rook joins the attack. The result is a clean tactical gain rather than a speculative attack.
