The forcing game with a freely selectable playing card - really!

The card game allows a very interesting approach (and includes several presentations):

The spectator names any card from a deck of 52 cards. A completely free and mentally chosen card.

The spectator is then asked to place a business card anywhere on the stripped deck—any position. The card immediately next to the business card is revealed and is, in fact, the card named by the spectator. Not only that, but the chosen card is the ONLY other card in a forcing deck (a deck of identical playing cards). The demonstration is absolutely astonishing!

Once again: The spectator names – without any force or forced choice – any card of his choice.
