if not checking for BJ with a 10 up then we also need to make sure that they aren't taking your 'double-money' when you split or double-down (usually when they no-peek with a T up they just take the original bet on a double-down if you lose the hand).


It's also possible that they never NEED to shuffle.
If they are using a continuous-shuffling-maching than card-counting just ain't gonna happen (because the discards are immediately put back into the shoe after each hand).


However...if you can see that it's a regular 6-deck shoe with decent penetration (and you trust them enough to not stack the deck...although I have no idea how or why you could actually have this amount of trust in them) then conceiveably it COULD be possible to count it.

It would also be possible for THEM to check your betting-patterns and see that you are pretty obviously counting just based on your bet variation.
but with some decent disguising and a VERY sophisticated count you might be able to make it profitable for a stretch without being detected.


However - just winning will be enough for them to take notice even if you use every single side-count index in Peter Griffin's Theory of Blackjack right down to getting to make goofy plays (when the count is right) like splitting your 3's against a 10 (which I got to do in a live casino once with a surplus of 7's and 8's remaining in the single-deck).


Even IF all the rules and dynamics are right to make it potentially +EV...it will NOT be +EV for you for very long because they will simply stop you from playing there.
And if they are REALLY snitty about it they might say "you were varying your bet-size in a really inappropriate fashion and you clearly are a professional. Therefore, your winnings are being confiscated by us because we think that card-counting is cheating."
I would suspect that the chances of this happening are higher than you might think. consider the number of online-casino 'bonus-abusers' (as they like to call them) who couldn't get their own money back.


In other words...there's no freaking way I would try to card-count at an online-site even if it WERE possible because the house just doesn't like to lose money.
In poker there is ZERO concern about winning money (for the most part) because the house makes their profit either way.
But in blackjack...the casinos have learned to become VERY protective against potentially winning players (even though most of them actually aren't long-term winners).
