hey guys i want to know how u guys study The book expert at the card table? do u guys read while having the deck infront of you and doing the moves or is there any other ways u guys did?
This is a really hard question because people's learning styles vary wildly. This is additionally complicated with Erdnase because sometimes you get an extra little tip on a move from something later in the book, so it's not as simple as learning one technique thoroughly and then moving on. It can definitely be useful to get the fingers working, and the muscle memory starting, as you go through the book, but the true student will keep going back over what he has learned to hone and perfect.
As regards the DVD issue, I own both the Wesley James and Allan Ackerman sets. You can safely ignore Wesley James' one, except maybe as a source of comedy. The Ackerman set is superb in many ways, especially the extras covering the history of the book and the identity issue. Be aware, though, that it's still not completely definitive. Allan Ackerman is a great card man, but I think there's room for debate on his interpretation of some of the moves.
