Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In shuffling never riff or mix the cards in. A person may take as many as they like from one side and place them on the other. As long as you do not take cards from the center of the pack, but keep shifting cards from one side to the other, it will not affect the system. This is what is called a false shuffle and with a very little practice a person is able to fool the best of them.
