It would be simple if for instance the cards weren't shuffled every hand which is what most sites do and you don't know if they're using 6 or 8 packs of cards.
but as far as casinos its seems it would be impossible. even if they weren't always shuffled. I mean counting 1 deck seems hard enough and must be done with a group now imagine 8 decks.
But I mean maybe some one out there is able to but would seem pretty crazy to think they could keep it up.
Oh I didn't know they use 6-8 packs of different cards. If they did, wouldn't the same card have a chance of appearing more than once?
Yes you mean picture cards ? Of course that's why you sometimes get a good run of cards for dealers and players.
I mean if you're playing with more than one deck, wouldn't the chance of getting 9 of hearts and 9 of hearts again be possible?
