The basic blackjack strategy is based on this statistical analysis and the fact that the player may choose to double down or split when favorable 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.

It is a 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.

RULE VARIABLES AFFECTING THE BASIC BLACKJACK STRATEGY
There 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:

The number of decks used.

Does the dealer stand on a soft 17 (Ace & 6).

How many times is it allowed to split hands.

On what cards is doubling down allowed
Is double down allowed after splitting pairs

Is surrender allowed. If so is it Early or Late surrender.

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.
