Three cards are shown, two deuces and a Queen. The cards are placed face down on the table and the spectator is asked to find the Queen.
 
You are willing to bet ten dollars against a drink he can’t pick the Queen. He is certain he knows the location of the Queen so, of course, he tries.
 
Upon turning the supposed Queen over it is found to be an Ace!
 
All three cards are immediately ready for examination.
