THE EFFECT: The magician shows the four aces. They get shuffled by the spectator and they choose one of the aces. The spectator memorizes the ace and shuffles them again (the magician turns his back at that moment).
The spectator lays the aces face down on the table. The magician turns around and asks the spectator what there card is. The magician simply pushes one card up, out of line with the rest of the cards. The card is turned over to reveal the magician has chosen the spectators card!
