I was hoping for a more robust memory demonstration. Instead the routine is cut down to a spectator
picking a card from one half of the deck and putting it into the other half of the deck only IN THE
MIDDLE. So the performer has only a few alternative solutions, not like the whole pack.
Also, JB fails to discuss what happens if the spectator does NOT put the card in the middle and
is buried somewhere else. You cannot find the chosen card.
