Any card may be drawn--not "forced"--and returned to the pack. In
pretending to shuffle the cards, bring the selected card to the bottom
of the pack, and then slip another card in front of it. Show your friend
this card at the bottom and ask him if it is his. Of course he will say
"No." Lower the pack, and with the fingers of your left hand draw the
bottom card back about half an inch, and with your right hand draw out
the next card--which is the one chosen--and place it face down on the
table. Shuffle the pack and again show the bottom card, "Is this your
card?" "No." "Then I will place this one on the table"--which you do.
Repeat this, and place a third card from the bottom of the pack on the
table. Then say, "I am sure your card must be one of the three. No? Look
and see for yourself." He turns the three cards over, and of course
finds his card is one of them.
