You just want a win this weekend. Note: To learn how to win at blackjack over the long run, with or without card counting, start with our Intro to Winning Blackjack. There are two main types of betting systems for blackjack or any casino game—positive progressions and negative progressions. With a positive progression, the general theory is that you raise your bets after wins, which means that your bigger bets are primarily funded by money won.
This is a conservative betting system insofar as a long string of losses will not wipe out your bankroll as quickly as with a negative progression. With a negative progression, you raise your bets after your losses. This is more dangerous, since a bad run of losses can wipe you out quickly. The goal for any series of bets is to win just one unit, then start a new series. Each series starts with a one-unit bet.
After any win, the next bet is one unit more than the previous bet. After any loss, the next bet is identical to the previous bet. That is, if you lose a two-unit bet, your next bet is a two-unit bet until you have a win, at which point you raise your bet one unit to a three-unit bet.
A martingale is any of a class of betting strategies that originated from and were popular in 18th century France. The simplest of these strategies was designed for a game in which the gambler wins the stake if a coin comes up heads and loses it if the coin comes up tails. The strategy had the gambler double the bet after every loss, so that the first win would recover all previous losses plus win a profit equal to the original stake. Since a gambler with infinite wealth will, almost surely , eventually flip heads, the martingale betting strategy was seen as a sure thing by those who advocated it.
None of the gamblers possessed infinite wealth, and the exponential growth of the bets would eventually bankrupt "unlucky" gamblers who chose to use the martingale. The gambler usually wins a small net reward, thus appearing to have a sound strategy. However, the gambler's expected value does indeed remain zero or less than zero because the small probability that the gambler will suffer a catastrophic loss exactly balances with the expected gain.
In a casino, the expected value is negative , due to the house's edge. The likelihood of catastrophic loss may not even be very small. The bet size rises exponentially. This, combined with the fact that strings of consecutive losses actually occur more often than common intuition suggests, can bankrupt a gambler quickly. The fundamental reason why all martingale-type betting systems fail is that no amount of information about the results of past bets can be used to predict the results of a future bet with accuracy better than chance.
In mathematical terminology, this corresponds to the assumption that the win-loss outcomes of each bet are independent and identically distributed random variables , an assumption which is valid in many realistic situations. It follows from this assumption that the expected value of a series of bets is equal to the sum, over all bets that could potentially occur in the series, of the expected value of a potential bet times the probability that the player will make that bet.
In most casino games, the expected value of any individual bet is negative, so the sum of lots of negative numbers is also always going to be negative. The martingale strategy fails even with unbounded stopping time, as long as there is a limit on earnings or on the bets which is also true in practice. The impossibility of winning over the long run, given a limit of the size of bets or a limit in the size of one's bankroll or line of credit, is proven by the optional stopping theorem.
