Introduction to Blackjack Basic Strategy StatisticsStatisticians and mathematicians became interested in the game in the 1950s and calculated a strategy for eliminating much of the casino house advantage. These theories were further developed in the 60s and 70s when computers became more available. The researchers were able to simulate millions of hands of blackjack and developed what is now know as blackjack basic strategy.The basic strategy is based on this statistical analysis and the fact that the player may choose to double down or split when favourable and gets paid 3:2 for blackjack. Whereas the dealer must adhere to the rules and stand on 17 and above, cannot double down or split and only gets paid 1:1 for blackjack.For instance it is a statistical fact that the dealer has more than a 35% chance of busting if their face up card is a 3, 4, 5 or 6. So, in this case, if you have a total of 13 to 16, you should stand as the dealer has a good chance of busting, as do you, but you can choose not to hit whereas the dealer must hit.However if the dealer has a 7, 8, 9, 10 or Ace, you should take another card as there is a high probability that the dealer's face down card is a 10, and their hand will beat you.VariablesThere are certain variables that alter the casino's percentage advantage one way or the other and also have an effect on the correct basic strategy that should be used: Number of decks used . If the dealer has to stand on a soft 17 (Ace and 6). If splitting pairs is allowed, and how many times. If doubling down is allowed and whether allowed after splitting. If surrender is allowed. Winning at Blackjack is part skill and part luck. A player using a good blackjack basic strategy can reduce the online casinos advantage to a minimum and, under certain very favorable conditions, can gain an edge over the casino.
