Double Undercut
Have about half the deck in both hands, have the spectator replace the chosen card on top of the left hand stock. Place the right hand stock on top, or dribble on top such as to cover the pinky break you will catch above the spectator's card. Square up the cards, and transfer the break to your right thumb. Remove about half of the cards below the break, with your left hand, (kind of a pulling motion, keep right hand still as possible) and cut them to the top (still retaining break, will have to shove the stock underneath your right palm). Cut to the break with your left hand, drop the right hand stock on to the table. Drop the left hand stock on top of the cards on the table. Card has been controlled to the top.
