It's a five-card spread for use with specific questions. Five cards are chosen using whatever method the reader is comfortable with. The cards are laid out in a horizontal line from left to right.
The first card on the left is the situation as it stands now; what will happen if the querent takes no action and continues on the present course. The second card represents what the querent could do to change that situation, whether for better or worse. The third card represents why the querent is in this situation. The fourth card represents forces (internal or external or both) that can help or hinder the querent. The fifth card is what the outcome will be if the querent follows the changes represented by the second card.
