D+M What advice would you give to an enthusiast in card cheating tecniques but while being an intermediate in sleight of hand. Obviously theres S.W Erdnase and How to cheat at cards but which one provides better teaching for a analytical and perceptive student and observer. As a follow up will there be a How to cheat at cards Dvd, if so can you elaborate on its contents and specifics. Thank you very much Daniel Madison and Theory11.
