Queen's Gambit Declined Puzzle (Rated 929): Win a Fork — Decisive Material Gain
This middlegame puzzle is built around a forcing knight jump that creates a fork on the enemy king and queen. The key idea is to use active piece placement to win material immediately, not to launch a long attack. White’s knight becomes a tactical monster because Black’s king is exposed and the queen is vulnerable to a direct check. Once the king is forced to move, the knight can capture the loose queen and leave White with a decisive advantage.
