    Alexost: Blackjacks

    Does anyone know how many times per hour (or number of hands), a player can expect to get a blackjack for 1,2, and six decks? I'm guessing the frequency of blackjacks will be skewed towards those times when the TC is positive... Correct? If so, how skewed will the number of blackjacks be when the TC is either positive or negative?

    Sure, child's play. Do you want them untied, or can the dealer have one, too?

    Of course, but that's a different question.

    You want the frequency of naturals at each TC, right? See Norm's tables at qfit.com.

    > Tied and untied please

    One deck: 4.8265%; 4.6492%

    Two decks: 4.7797%; 4.5783%

    Six decks: 4.7489%; 4.5323%

    Tied and untied.

    > One deck: 4.8265%; 4.6492%

    So a tie should occur 4.8265 out of 100 hands, and a player should get blackjack and win 4.6492 out of 100 hands, for a total of 4.8265+4.6492 blackjacks seen between the player and dealer combined?

    I must not be interpreting your response correctly. I wouldn't think there'd more pushes than wins. ?

    Please translate Thanks

    Dog Hand: I think Don's headings were misleading...

    Don gave these values for one deck: 4.8265%; 4.6492%

    I believe the correct interpretation is that the player will receive a BJ on 4.8265% of the hands. However, he will receive an UNTIED BJ on only 4.6492% of the hands.

    Thus, the headings perhaps should be "Potentially Tied" and "Untied".

    The difference between these two figures is the percentage of hands with tied BJ's: 4.8265% - 4.6492% = 0.1773%, or just under 2 hands per thousand.

    If you want to know the percentage of hands on which the player or the dealer (or both) have BJ's, that would be given by this formula:

    Player BJ% + Dealer BJ% - Tied BJ%
    4.8265% + 4.8265% - 0.1773% = 9.4757%

    Naturally, the dealer's chance for a BJ is identical to the player's chance for a BJ.

    Hope this helps!

    Thanks Dog Hand, I was leaning towards this interpretation also.

    Thanks Norm, I already have CVBJ and CVCX. I will eventually get CVData too. I want to do some research on the ten count, so hopefully there will be some good options for this in future versions. I appreciate the time you spend providing these tables!
