The magician/psychologist has 10 reasonably good playing cards, he deals one to himself and one to the spectator. He then lets the spectator take a card (without seeing the face), and he does the same. This repeats until each player has a full hand. The spectator loses the hand every time.
This was performed by Derren Brown as a psychological experiment. I will explain to you how it is just a simple magic trick. This is an incredibly powerful trick!
