What is a Bias?

The American Heritage Dictionary, of the English Language (Houghton Mifflin, 1992) defines a bias as "a statistical sampling or testing error caused by systematical v favoring some outcomes over others."

A bias in Online Blackjack Games is when the card distribution or pattern in a shoe is such that the true percent advantage deviates from the normal overall advantage a casino enjoys in a random game where the players are playing perfect basic strategy.

Advantage is the average amount of money won divided by the total amount of money bet. For example, if a casino enjoys a 1 percent advantage, then the casino expects to make$1 for every S 100 bet (1 percent X $100).

As you may know, the casino hold percentage (the percent of player buy-ins left behind by the players, or percent losses) is consistently much higher than the casino's theoretical advantage in all casino games. Most of this discrepancy is probably due to players over betting their bankrolls and tapping out. Some of it is chic to poor play decisions by the players. The average player probably gives up about 4-6 percent by poor play.

Above and beyond these factors, some of this discrepancy is due to non-random drift, casino shuffles, and the sorting of the cards by normal dealing, player hitting, standing, breaking, and dealer card pickup procedures. Most of the non-random card patterns that develop favor the casino. Many of the casino shuffles not only will tend to preserve a dealer biases, especially in full tables. Other casino shuffles tend to preserve either bias-dealer or player. Since the normal sorting of the cards during dealing and playing usually favors the formation of dealer biases, and because the casino enjoys a theoretical advantage overall, dealer biases are the most common type of bias.

The Game Begins with Everyone Anteing a Predetermined Amount
The dealer gives everyone two cards face down and one card face up. This up card is often called the player's doorcard. A round of betting follows the deal with the player who shows the lowest card being forced to make what is called a bring-in bet.

Because seven-card stud is played for high, normally you would prefer not to face a forced bet when showing the worst card. The forced bring-in bet creates two different sums for the first raiser to attack: the antes and the bring-in. In some ways, this makes getting stuck with the bring-in worse than having the blinds in hold'em. At least in hold'em, your blind hand might be A-A. In seven stud, the forced bettor is starting with a card that is almost always bad. To compensate, the bring-in is smaller than a hold'em blind.
