Defensive Move Intermediate Puzzle (Rated 1109): Win a Queen Endgame — Crushing Defensive Move

This chess endgame is a great example of how queen activity and king safety can outweigh raw material balance. One side’s king is exposed, while the stronger queen coordinates with passed pawns and centralization to create a decisive tactical refutation. In positions like this, the best move is often not a flashy attack, but a precise defensive move that keeps the enemy king boxed in and preserves the winning net.
