As a space filler, I can do no less than pass on what has been for me an
exceedingly nice and sure location. It will be of good use to those who like
to dabble with such momentary “pop-ups”, as I term them, and who want
something sure to fool the better card experts.

You lay the deck down and ask someone to give it a good dovetail shuffle
so that no card can be in a known position. Tell him to pull a card from out
of the middle of the pack, look at it, put it on top and cut the deck several
times. You take back the cards, run through them face up, remove a single
card, toss it out face down, and it subsequently proves to be correct.

Jordan dug out this base principle years ago when working with the
dovetail shuffle, and later it was revamped by Edward Bagshawe in one
of his books. However, it depended upon the card being between two keys,
along with several or more cards that might be shuffled in between the
keys also. Then one had to use an elimination process to pick out the right
card from the group.

By putting the 13 cards of one suit in the center of the pack, and noting
the top and bottom cards as key cards, the location is positive. Spectator
gives the deck a dovetail shuffle, pulls a card from the middle, puts it on
the top and then cuts. The chosen card will always be found somewhere
between the two noted keycards, and although there may be a number of
other cards also between the keys, these other cards will all be of the same
suit, the stacked suit you originally had in the deck’s center. The one card
of another suit is THE one, without any discussion, questions, or guessing.
