Take another 8 out of the deck. I would have to do a computer simulation to consider all the other combinations. Because the sum of a large number of random variables always will approach a bell curve we can use the central limit theorem to get at the answer. That column seemed to put the mathematics to that "feeling" a player can get. I know, I know, its some sort of divine intervention betting system I am talking about and no betting system affects the house edge. However there are other ways you get four aces in the same hand, for example the last card might be an 8 or 9. Determine the probability that the player will not get a third eight on either hand.

There are cards remaining in the two decks and 32 are tens. It took me years to get the splitting pairs correct myself. Cindy of Gambling Tools was very helpful. My question though is what does that really mean? Multiply this dot product by the probability from step 2. If I'm playing for fun then I leave the table when I'm not having fun any longer. Go through all ranks, except 8, subtract that card from the deck, play out a hand with that card and an 8, determine the expected value, and multiply by 2. For each rank determine the probability of that rank, given that the probability of another 8 is zero. Unless you are counting cards you have the free will to bet as much as you want. So standing is the marginally better play. These expected values consider all the numerous ways the hand can play out. So the probability of winning six in a row is 0. The probability of this is 1 in 5,,, For the probability for any number of throws from 1 to , please see my craps survival tables. To test the most likely case to favor hitting, 8 decks and only 3 cards, I ran every possible situation through my combinatorial program. Besides every once in awhile throwing down a bigger bet just adds to the excitement and for some reason it seems logical that if you have lost a string of hands you are "due" for a win. For how to solve the problem yourself, see my MathProblems. Repeat step 3 but multiply by 4 instead of 2, and this time consider getting an 8 as a third card, corresponding to the situation where the player is forced to stop resplitting. Expected Values for 3-card 16 Vs. From my section on the house edge we find the standard deviation in blackjack to be 1. Any basic statistics book should have a standard normal table which will give the Z statistic of 0. The following table displays the results. If there were a shuffle between hands the probability would increase substantially. In general the variation in the mean is inversely proportional to the square root of the number of hands you play. Blackjack is not entirely a game of independent trials like roulette, but the deck is not predisposed to run in streaks. There are 24 sevens in the shoe. You ask a good question for which there is no firm answer. When I said the probability of losing 8 hands in a row is 1 in I meant that starting with the next hand the probability of losing 8 in a row is 1 in The chances of 8 losses in a row over a session are greater the longer the session. Here is how I did it. It depends on the number of decks. In that case, the probability of a win, given a resolved bet, is The probability of winning n hands is a row is 0. Multiply dot product from step 7 by probability in step 5. What you have experienced is likely the result of some very bad losing streaks. There is no sound bite answer to explain why you should hit. So, the best card for the player is the ace and the best for the dealer is the 5. Putting aside some minor effects of deck composition, the dealer who pulled a 5 to a 16 the last five times in a row would be just as likely to do it the next time as the dealer who had been busting on 16 for several hours. Repeat step 3 but multiply by 3 instead of 2. The standard deviation of one hand is 1. You are forgetting that there are two possible orders, either the ace or the ten can be first. If you were to add a card as the dealer you should add a 5, which increases the house edge by 0. Steve from Phoenix, AZ. As I always say all betting systems are equally worthless so flying by the seat of your pants is just as good as flat betting over the long term. Following this rule will result in an extra unit once every hands. Thanks for the kind words. This is not even a marginal play. I recently replaced my blackjack appendix 4 with some information about the standard deviation which may help. However if you were going to cheat it would be much better to remove an ace, which increases the house edge by 0. What is important is that you play your cards right. Let n be the number of decks.
