but first let me say that this particular stack was first credited to Si Stebbins (hence the name) also know as William Coffrin. It was first published in the United States in Si Stebbins' Card tricks and the Way He Performs Them in 1898.
Step 1: The Stack
Well first there's the order of the Suits. The Order goes Clubs, followed by Hearts, followed by Spades, followed by Diamonds. To help remember that order there's a word that helps, I know it's simple enough that you shouldn't need help to remember the order but some do, the key word here is CHaSeD, see?
ok the suites was(were?) the simple part, now we move on to understanding and ordering the values. To begin with, each card even faces are given a numeric value. The numbered cards are easy to figure out but the faces each have a different value as well. Aces are all 1, while Jacks are 11, Queens are 12, and Kings are 13, easy enough right? now that we have the values figured out the actual order is this: +3
That's right, each following card is a value three more than the one before it. If the card on top of the deck is the 6H(six of hearts) then the next card down is going to be the 9S(nine of spades), and the one after that is going to be the QD(queen of diamonds) but if QD has a value of 12, the next card is three more that would be 15? well because there is no 15 you have to start the count over at 1, so because 15 is 2 more than 13 your next card value is 2 which makes it the 2C( two of clubs)
see how easy that was? maybe? I hope I explained that clear enough
super simplified: CHSD+3
Some notes about this stack before we move on to a routine. If you haven't noticed already three cards separate matching suites thirteen cards separate matching values. Also this wonderful man made a great video explanation you should check it out if the above was too confusing.
Step 2: The Routine
(what the spectator see's): To begin your volunteer selects a card at random
(what you're doing): you cut a six to the top and false cut forcing the six
Patter suggestions: tell them to look at the card and remember there card and remind them that it was their choice (we know it wasn't) and that if they want they can show it to every one else as long as they don't show it to you. Tell them to keep it and to hide it away, a pocket or purse will work, just so you can't see the card at all.
More Patter and Show: Now that they have their card hidden the intensity begins, don't say a word, look at them with unblinking eyes, creepy and scary is what we are going for here. Silently count off three piles of thirteen cards without changing their order. Occasionally cock your head as if listening to something that only you can hear. Drag this process out with out a word, and if you ham it up right there'll be palling silence over every one watching. Continue till all there are three piles of thirteen in front of you. Put the remaining twelve cards away, you won't need them. Inform your spectator that you know their card, however don't just go out and say that it's the six. One by one pick up a pile and deal the cards in front of you thus reversing the stack of the pile puting a six on top. Finish each stack by dealing the six face up while the rest are down. Spout mumbo jumbo about the thirteen gates of hell and the number of the beast (666), allowing you to know that the selected card was (name their six).
feel free to modify that, I also use 7 when I'm around religious sensitive people instead of six's for this spouting off stuff like getting the lucky triple seven even when I'm stuck in a bad run of luck
