An Easy Substitute for the Pass
This is a simplification of the Charlier one hand pass. You hold the pack by its sides at the tip of the thumb on one side and the tips of the second and third fingers on the other. As you advance the pack toward a spectator, inviting him to replace a card he has previously drawn, you allow the lower half of the pack to fall into the fork of your left thumb. (Fig. 6-A). You have the card placed in the opening thus made and at once drop the upper packet on top of it. (Fig. 6-B).
This procedure looks perfectly fair, but in dropping the top packet you pushed it out a little so that instead of falling squarely on the lower packet, it lies a little to one side, so making a step between the two packets (Fig. 6-B). The chosen card is on top of the lower packet.
You proceed at once to an overhand shuffle. As you take the pack in your right hand your left thumb falls naturally on the back of the chosen card, and you pull it out in the first movement of the shuffle. (Fig. 6-C). You then shuffle off the rest of the cards on top of it in the regular way. The chosen card is thus brought to the bottom of the deck and can be disposed of as may be necessary for the trick in hand.
