The first and most common use is the bet placed on a particular play or it can mean the total sum played over a period of time. The third meaning is simply that a game is in progress.

Advantage – This refers to the statistics present in the game of blackjack. It is generally given that the house or casino has a statistical edge or advantage over a player, however card counting and other advanced techniques can switch this percentage into the players favor giving them the advantage.

Anchor-Anchorman – Also known as the ‘third base’ this is the seat farthest away from the dealer who receives his or her hand last. This can be especially difficult for new players and this seat has the potential to hit or stand in a way that confuses or complicates the players proceeding.

B

Balanced Count – A card counting system that has a balanced, or equal number of cards that are positive or negative so that the total deck is valued at 0 or null.

This means that the chips should line up according to color, or value and this is how the term came into use.

Basic Strategy (BS) – The most optimal strategy for playing blackjack that does not include card counting. It may also be referred to as the zero memory strategy. Instead of card counting this utilizes the total of players hand and the dealers up card. A successful Basic Strategy minimizes the casino advantage to between 1.5% – 0.5%

Usually expressed as a decimal number a .97 count would mean that the betting correlation is correct 97% of the time.

This means the calculating the best time to raise a players bets related to the true count.
