Blackjack computer

I remember in the 70s/80s Taft created multiple computers to help him win some money. Throughout the years, other players have also used computers to aid them in beating blackjack. Of course, since Nevada outlawed blackjack electronic systems, many players are thrown in jail when getting caught. Although, there are a few who still get away to tell the tale of making millions by cheating blackjack.

If a player were to create the most sophisticated, hidden stealth-like blackjack computer now days, what all would be involved to beat the casino?

I know the computer would have to some how analyze each hand along with single-double-multiple decks and be able to count in card shuffle analysis. What else could someone do to actually beat blackjack with a cheat device?

EDIT : FOR INFORMATIONAL PURPOSES ONLY

No matter how small, sophisticated, and well-hidden, it would still be cheating.

It would still probably be noticeable, as using it would probably slow down the game a bit.


As for what it would do... track every card dealt (and discarded), look for clumps that survived the shuffle (ideally with a good understanding of the shuffle being employed), probably track more than one deck (two decks for machine shuffle tables), do an analysis of the remaining deck composition (based on prevously seen cards), and suggest ideal plays for the particular situation.

An advanced version would also track bankroll and the current advantage, and suggest optimal bets. If there was an advantage to making a less than full bet for a double down, it would suggest that, too.

Of course, nobody we know would do any of this, since it would be cheating.
