I'm doing research on a principle but I can't find a name for it. I spent last night combing through T.A. Waters, MIND, MYTH AND MAGIC, but couldn't find anything really on point.
Here's a simple example.
The spectator gives you any number from 1 to 5. You pull out a list that is numbered 1 to 5 and opposite each number is a card (e.g., 1 = AS, 2 = 4H, 3 = 10D, etc.). So, if he picked 2, his card is the 4H.
What he doesn't know is that you forced the 4H because you have 5 lists. On list 1, the 4H is opposite #1, on list 2 it's opposite #2, etc. So no matter what number is chosen, you can pull out a list that forces the 4H.
The only precursors I could find for this principle (and they are not right on point) are Al Koran's "Insight Spectacular" (in AL KORAN'S LEGACY) and in MIND, MYTH AND MAGIC, "Symbo Chart (510) and Symbold (713).
In these tricks two separate "documents" are consulted to provide a result (usually a prediction), but the combination, though it looks unique, can be adjusted to produce any number of results.
I'm also interested in any uses of the "Magic Stamp Book" principle (i.e., short pages, long pages) for mentalism.
Any assistance would be most appreciated.
