If you know how the pieces move but still lose your queen to a one-move blunder, this focused eBook helps you practice the specific skill you need: recognizing when your queen is under immediate threat. Follow a self-paced five-day sprint through four short drill chapters: The Move That Changed the Queen’s Safety, Lines, Jumps, and the Queen, A Defender Is Not a Guarantee, and The 12 Position Sprint. Use the Queen Safety Snapshot card to replay an opponent’s last move, scan for direct attacks along lines and knight jumps, and check whether a defender can actually respond; then apply those skills to a 12-position scorecard and review any missed cues. The drills use visual, notation-free practice and stay focused on queen safety—not long opening variations, full-game review, or a broad chess curriculum. Work through the ebook independently and check your progress against the sprint’s goal of correctly identifying immediate queen threats in at least 10 positions.
