Queen Endgame Puzzle (Rated 1193): Win with Queen Endgame Interference

This chess endgame is a classic example of interference: the attacking queen steps onto a key square to block the defender’s coordination and force the king into a worse route. In queen endgames, activity matters more than material, and the side with the more active queen often creates decisive threats against weak pawns and exposed kings. Here, the defender’s queen is overloaded, so one forcing check can unravel the entire position and turn a small edge into a winning attack.
