HOW TO WIN WITHOUT GETTING KICKED OUT
Blackjack Cards Count Per Deck
The high-low count tells you when the best cards, the 10s and aces, outnumber the small cards. The richer the pack, that is, the more 10s and aces relative to small cards, the better for you.
You need to know how rich the pack is in order to make appropriate bets and decisions in play
Richness of the pack depends on the proportion of excess 10s and aces. For decision purposes, you must relate the running count to the number of decks you have not seen.

Blackjack Cards Count Examples
For example 1:
Twelve 10s and aces remaining to be used when the dealer is halfway through a single deck is two 10s and aces more than average; that is as favorable to the player as if there were four excess 10s and aces in 52 cards, and is described as a count per deck of +4.
For betting and playing decisions, a running count of +2 with one deck remaining is equivalent to a running count of +1 with half a deck remaining, to a running count of +4 with two decks remaining, and to a running count of +8 with four decks remaining. Therefore, you must convert the running count into count per deck for making decisions. Simply divide the running count by the number of decks (or fraction of a deck) that you have not seen. If less than one deck remains, your count per deck will be greater than your running count. If more than one deck remains, your count per deck will be less than your running count.
For example 2:
Suppose you approach a blackjack table with a single-deck game in progress and see the following cards.
You glance at the cards and see that the running count is +3.
Since what you have not seen is almost one deck, the count per deck is slightly above +3. The dealer picks up the cards, and you place a bet. You receive 2-10, the dealer's upcard is 2, the first other player has a natural, and you do not see the second other player's cards.
You must decide whether to hit or to stand. The running count is now +2. Since about 2/3 of the deck remains unseen, you divide by 2/3. This is the same as multiplying by 3/2. It gives a count per deck of +3.
You need to only approximate the count per deck. You do not need an exact count of the number of cards remaining. If you had seen roughly half a deck in a single-deck game, a running count of +2 would translate to a count per deck of about +4. If you had seen about half a deck (26 cards) in a double-deck game, a running count of +2 would translate to a count per deck slightly greater than +1 (2 divided by 1.5 gives 4/3). A rough estimate of the count per deck suffices for decisions because you need to know only whether it exceeds an integer in a table.
