strategy can be either total-dependent or com-position-dependent.
Total-dependent means the decision rules require only
the dealer's card and the total points in your hand.
Composition-dependent means the decision rules require
knowledge of the dealer's card and the precise cards
that make up your hand. For example, total-dependent
strategy says stand on twelve against 4. Com-position-dependent
strategy for twelve against 4 requires you to specify
how you get to twelve: Do you have 7-5,8-4, 3-2-2-5,
or what? If you got to twelve by 10-2 or 2-10 (where
10 means any 10-count card), and only one deck is
being used, you should hit. If you got to twelve by
any other route, or multiple decks are being used,
you should stand.
are few differences between composition-de-pendent
and total-dependent strategies for single deck, and
none that are important for multiple decks. (The more
decks shuffled together, the less difference one card
makes.) This site uses total-dependent strategy.
