The deck is first fanned to show all of the cards as being different. You then force a card using a corner riffle with the spec saying STOP anywhere he/she likes. You then use your favorite method of producing the force card.
With the right method you can get the spec to hold the deck and get them to riffle and stop where they want which makes the force seem very natural.
