    Why does the HE change with the more decks that are in play. I understand that less decks are in favor of a player assuming they can count and vary their bets. But I would thing that a math calculator would not take that into considerdation. It seems to me that adding more decks would not change the math of the game.

    Explanation?

    Whether or not you are counting cards, removing cards changes the composition of the deck(s) involved...

    My understanding is that it has to do with blackjacks. Basically, it's because fewer decks make it 1) more likely to get a player blackjack, and 2) less likely for a blackjack-blackjack push between player and dealer.

    This all happens because the cards you've already been dealt have a much higher impact on what you could get when there are fewer decks. This changes the likelihood of blackjacks, the effectiveness of double downs and a few other things.

    The blackjack is easiest to explain. Say I just dealt you an Ace in a one deck game. What are your odds of blackjack? 16 tens left in 51 cards.

    In 2 decks its 32/103

    ...

    In 8 decks its 128/415

    16/51*100= 31.37%
    32/103*100= 31.07%
    128/415*100= 30.84%

    This is exactly correct.

    To provide the simplest example, say you are on the first hand and your first card is a 10. At single deck, your odds of putting an ace on that 10 are 4 in 51, or 7.843%. If you were playing 8 decks, your odds are 32 in 415, or 7.771%.

    I like this board because even when I'm too lazy to do math, someone else will do it for me and still tell me I'm right. :beer:
