Defensive Move Intermediate Puzzle (Rated 2007): Defend — Quiet Move

A defensive move is often quiet but strategically powerful. In this middlegame, Black must coordinate active queen and bishop pressure around the exposed white king while keeping the position under control. The key idea is to improve piece activity and restrict counterplay instead of chasing an immediate tactic. Strong defense can preserve attacking potential, protect critical squares, and maintain a noticeable advantage even when material is imbalanced.
