Derren Brown has a long history of impressive casino tricks, often misspelled as Darren Brown. He has demonstrated an easy manner of counting cards and thus turned Blackjack’s odds to the player in his famous series of Mind Control. The casinos were upset and the ban remains valid today.

I recall Derren well during the Bristol University gatherings, where he amazed us as a student with his magical achievements. By seemingly simple acts, the students were often reduced to tears of disbelief.
