FORCE by Pierre IACCARINO
A new technique to force a card
Before the trick, a prediction is placed on the table.
A card is chosen by the magician. When the spectator says "STOP", the magician inserts the card into the deck.

The first card at the right of the other is the spector's card. 

The choice of the spectator was completely free and yet if we look at the prediction, IT MATCHES !
