After the spectator has chosen a card. Overhand shuffle some of the deck, still retaining some stock in the other hand. Have the spectator replace the card on top of the shuffled stock. Run off one card on top of the spectator's card, but jog it towards you about half an inch (such that the card on top of the spectator's is not completely on top of the deck, but is hanging over the edge slightly). Shuffle off. In an apparently, squaring up action, catch a break beneath the jogged card and shuffle until that break. Then throw the rest of the stock on top. The card has been controlled to the top. If you catch a break above, you can control to where it is second from the top.
