The Stop Force
1. This force, looks even better, because you actually ask the spectator to tell you to stop any place on the deck and HE selects the card at the stop point. Start by cutting the deck and placing the card to be forced at the top of the bottom portion of the deck.
2. Now, you’ll be doing a very useful move named the little finger break. This move consists in leaving your little finger over the peeked card, so you can easily cut to it.
3. Now, riffle the deck and ask your spectator to tell you to stop in any place
4. When the spectator calls stop, you’ll stop at the break. (requires practice)
5. Give the spectator the card he selected. 
Now that you know this two forcings, the possibilities are endless, because the spectator thinks that it was a free selection, but you already know which card he has selected. Ask him to replace the card in the deck and shuffle it as many times as he wants. Then, take the deck back, locate the card and reveal it.
