This is used by many of the gamblers, and is done through the neglect
of the players. The man doing this will always draw three cards, no
matter what he may hold in his hand. It is done by placing the cards
he wishes to keep on top of the ones he wishes to discard, and laying
them down beside him, ostensibly discarding them. As he is given his
three cards he looks them over and has eight cards out of which to
pick his hand. Suppose in his original hand he held three diamonds and
a club; he places the three diamonds beside him and calls for three
cards, holding one diamond and the club in his hand. When his cards
are dealt him he has five cards out of which to pick two diamonds. He
selects two cards and discards three cards; at the same time he picks
up the three cards that he discarded first. Very few are expert enough
to this trick without detection.
