1. King & Queen vs. Lone King (The Shrinking Box Method)
A Queen cannot deliver checkmate alone — she requires the assistance of her King to deliver the final blow on the board edge.
- Use the Queen like a Knight away from the enemy King, slicing the board into an ever-smaller rectangle.
- Trap the defending King on one of the four outer edge files (a or h) or ranks (1 or 8).
- IMPORTANT: Leave the King at least two squares of movement! Do not crowd too close without check, or you will cause an accidental Stalemate.
- March your own King up to stand in front of the enemy King, and deliver the final Queen kiss of death (Q directly adjacent to King protected by your King).
