HAVE a spectator shuffle the pack, take it and run cards from the left hand into the right, asking him to stop you at any point. When he does so separate the cards at that point and hold the right-hand packet before his eyes, spreading the indices of the last five or six cards and telling him to make a mental choice of one card. In the meantime turn slightly to the left away from him and with the left thumb lift the lower left corner of the top card of the left-hand packet and sight the card. Square the right-hand packet and drop it on top of the cards in your left hand. Have the pack cut several times with complete cuts. You have only to locate the key card and finish the trick in your favorite way.
