As a reward for reading this far, here is a free magic effect for you. Anyone can do it: there are no sleights.
Effect:
Someone shuffles a deck of cards, and cuts to any card, which he remembers. You unfailingly identify this chosen card.
Here's how:
After the mark shuffles the deck, he deals a face-down bridge hand for you and one for himself (ie 13 cards each). The rest of the deck is put aside. Say, "I want you to take a packet off the top of my bridge hand. Like this." By way of demonstration, reach across and take a packet off the top of HIS bridge hand. The mark cuts a packet off the top of YOUR bridge hand and notes the face card.
With the cut-off packet still in your right hand, point with your right index finger to HIS bridge hand, as you ask him to drop his held packet on top of it. As you point, sneak a glimpse at the face card of your own held packet. (This is your key card.) Then drop your held packet on top of your own bridge hand. The mark is invited to drop either bridge hand on the other, and to cut the resulting 26-card packet as often as he wants.
Then he deals to you a final bridge hand of 13 cards. He keeps the remaining 13 cards as his own hand, and puts it on the table. There seems to be no way you could know his card. Ask him which bridge hand he thinks contains his card. Pick up the hand he points to, and look through it for the key card you glimpsed earlier.
If the key card IS there, tell him his intuition was wrong. But you now know where the mark's chosen card is - in the other bridge hand, and as many cards from the top of that packet as your key card is from the face of the packet you are looking at.
If your key card is NOT there, say, "You're right, your card is here."
Pick up the other packet, and spread it to show the mark that his card is not there. But your peeked card will be there. Note how far it is from the face of the packet. The mark's chosen card will be the same number down from the top of the other packet.
Rather than just counting down to the chosen card, get the mark to deal cards into a face-down pile, spelling as he goes (one card for each letter). Use his name, or yours, or the name of the card, or hey presto, or whatever will get him to the card.
If he asks you how you did it, looks suitably mysterious, and tell him there is even better stuff in the other books mentioned on these pages.
