Basic Checkmate Geometry: The King & Queen Dance
Position 1 / 1
Mainline (29 Moves)
White plays 1. Qd3+! We check the King. The Queen's vertical and horizontal lines create a fenced 'box' trapping the King in a 24-square zone.
Black retreats the King to c5. The King is now trapped in a smaller 15-square box.
White plays 2. Qe4! Notice the Queen is exactly a Knight's distance away from the King. This shadows the King's move and locks it in a 16-square box.
Black steps to d6 inside the box.
White plays 3. Qf5! We maintain the Knight's distance. The box shrinks to 15 squares.
Black moves to c6.
White plays 4. Qe5! Staying a Knight's jump away, we shrink the perimeter to a 12-square box.
Black steps to d7.
White plays 5. Qf6! Maintaining the Knight's distance, the box is down to 10 squares.
Black retreats to c7.
White plays 6. Qe6! Squeezing the King into a tight 8-square box by staying a Knight's jump away.

White plays 8. Qe7! The box is now a mere 4 squares.

WARNING: This is a classic stalemate blunder and a perfect example of what happens when a player ignores the Golden Rule! By placing the Queen on c7, the box is shrunk to zero squares. Because the Black King is not in check but has absolutely no legal moves left, the game ends in an immediate draw by STALEMATE. This is a common way players throw away winning positions. Remember: the winning side must always leave the defending King at least two squares of breathing room until the attacking King arrives to help!
