Varying Basic Blackjack Strategy

When Counting Cards

The Basic Strategy is calculated based on an even deck, assuming that any type of card
always has a 1 in 13 chance of being dealt. However, when you are counting cards you
have a better idea of the mix of cards remaining in the deck. If you are really keen on
applying all the tricks, then the basic strategy should be varied depending on the various
True Counts.

The extra advantage gained by this is fairly minimal, and in my opinion not worth the
effort of having even more things to think about.

             

*Disclaimer* If you gamble using any of the strategies suggested here, you do so entirely at your
own risk. I accept no responsibility for any consequences that may result through applying the
information presented here.

You have been warned!

The tables below show the best actions to take based on Basic Strategy and the various
counts and side-counts.

D = double , H = hit , S = stick , P = split

The number in parentheses following an action indicates the True Count value required before
you should take that action. If negative, the True Count must be that value or less (further from
zero); if positive, the True Count must be that value or greater.

The lines in each table give :

  • Basic strategy
  • Hi-Opt-1 variation ("hi")
  • Aces side-count variation ("As")
  • Sevens side-count variation ("7s")

Remember, the Aces side-count is positive for excess aces remaining to be dealt,
and the Sevens side-count is negative for excess sevens remaining to be dealt.
