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
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
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.
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.
