also check out cardsharp by darwin orwitz, its apparently quite good.
theirs a few 1on1s here at t11 on the most (what I would say) important sleights for cheating, s.w.e shift, bottom deal, second deal, and false cut.
I'd like to pick up some points made by other posters on the 1-on-1s. The Diagonal Palm Shift and the SWE Shift are not gambling or card table moves. They could potentially be adapted into a magician's gambling routine, but they were never intended to be used to cheat.
If you actually want to learn to cheat at cards, then there isn't any book or DVD that can teach you. You need to get yourself a speciality, maybe bottom dealing, and then learn a practical version of the auxillary moves you'll need for a bottom deal to work in a real game. So, you'll need a good, natural-looking false shuffle and cut, and some method of nullifying the cut. Maybe you'll also want a cull, or you may choose to cull from the discards. Also, you might want to learn to hold out. Basically, find a process that works for you and practice it until your fingers bleed
However, if you want to perform gambling sleight-of-hand as a magician, then there are a load of good sources.
The Expert at the Card Table, Expert Card Technique, Down Under Deals, Hand Mucking and Gene Maze and the Art of Bottom Dealing would probably be my favourite books for this kind of stuff at the moment.
Daniel Madison's Card Cheat Handbook. It was released in little quantities. Its only Chapters 12 and 13 of the whole Card Cheat book. It basically about Marked Decks. Chapter 12 is about The Blood marking System and Chapter 13 is about the Blood Stack. Its 51 pages long.
