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:

  • 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.
