Query: Good beginner's text but extremely outdated

This was probably the best introduction available to the art of card-counting. Unfortunately, the 1983 edition teaches concepts which are useless in today's casinos (such as "depth charging"). The game is no longer single-deck dealt to the bottom, but rather multiple decks dealt only partially, or (occasionally) single decks with bad rules dealt out only partially.The two systems presented, "Red 7s" and "Zen", are still useful today, although "Hi-Lo" and "KO" are more widely used and (in the case of KO) more modern.Nevertheless, if you are just beginning to learn the game, this was the best book. I look forward to seeing the 1998 edition, to see how well it has been updated.
