Defensive Move Advanced Puzzle (Rated 1962): Defend — Quiet Move
A defensive move can be the strongest way to preserve an advantage when several tactical threats overlap. In this middlegame, White has more space and active attacking pieces, while Black is materially ahead but has cramped, pinned defenders and an exposed king in the center. The key idea is to improve king safety and maintain pressure at the same time. A precise defensive decision prevents Black from simplifying favorably and keeps the trapped pieces under tactical restraint.
