    Algo vs real BJ

    Hi, wondering is it best to play real BJ online (person/cards) vs computer generated coded program? I just played on Sky Vegas program BJ and I couldn't believe how many times dealer had great hands and I struggled to win twice in a row untold amount of times. I didn't count how many times this took place, but it felt like it lasted way too long even for random outcome.

    If the rules and conditions are the same, and the program is fair, there should be no difference. There is an obvious problem when it comes to verifying the latter. Drawing any conclusions from a few sessions is useless.

    "Untold" ? That whining has been heard multi-millions of times.

    If your winning chances on any given random hand is roughly
    43%, the square of .43 = 18.49%

    so ... TRY to understand that the product of the probabilities
    is what you need to look at. 18% is far from 50%, eh ?

    How long is an average losing streak? I had it again dealer kept having great cards when I kept busting out (standard strategy).

    Doesn't constant reshuffling lower the house edge for the basic strategy player?

    This doesn't answer your exact question but you might find this link satisfying nonetheless: https://blackjackincolor.com/useless3.htm

    At the end of the day, having the answer won't give you any predictive value such that you could either take advantage of it or simply be able to comfort yourself that it will soon be over.

    A more common metric to gauge how unlucky you are is calculating something called a z-score which is just a standardized way of expressing how much money you lost compared to how much you should have lost on average. From that you can calculate the probability of doing as bad as you did or worse (the probability of obtaining that z-score or worse). It's something you can find in any first year stats textbook and shouldn't be too hard to look up and be able to do yourself. Alternatively, I'm sure you can find calculators to do the math for you.

    The basic strategist's play is unaffected by depth of penetration. One round or many rounds.

    If the cards are shuffled after every hand rather than dealt from a shoe then there is a small reduction in the house edge due to the cut card effect. The lower the number of decks the greater the difference.

    While this is correct, it is certain that it is more than entirely offset by the greater number of hands per hour (20%?) that one will play at a CSM, for lack of shuffle time. So, to me, it is clear that the basic strategy player will surely lose more per hour at a CSM than at a hand-shuffled game, despite the lack of the CCE.

    Yes, agreed. The effect of playing online and the use of a CSM is the same which will lead to greater losses for the BS player due to the increased speed of the game.

    ditto.

    To the OP, kozlikha, nothing short of counting or taking advantage of promotions will net you a long-term advantage. Even then, you'd still have swings.

    If you're looking for fun. I'd imagine the best bang for your buck is the live deal blackjack. You'll have a low average loss/hours and might get more enjoyment per hand.
    If you're trying to make money I think the best advice would be to look for something outside of gambling. Gambling isn't the place you should look to make a quick buck.

    I saw an example of live deal blackjack by some dealers that obviously got demoted from the party pit, 4.5/8, H17, out of an autoshuffler. This is not something anyone is going to play other than for fun? I'm not seeing much in the way of any long term profitability going on there! It's not a good game. It would be a better game if the party pit dealers had their tits out, but outside of that, it's nothing profitable... Unless you happen to be the one running the online gaming operation incorporating tits into it so no one cares about it being 4/8 H17 out of an autoshuffer! A roulette table, a few carnival games, all using hot looking topless dealers. It's a brilliant idea, only a question of legalities... located in the right time zone I guess, but it'd make money!

    I know of one website where it's already been done. I'm sure the legalities would be fine since most online casinos operate far away, usually the Caribbean, from their targeted audiences anyways.
