Shuffle Tracker's Effect
does a shuffle tracker affect others?
A shuffle tracker will also have an effect on other players, but
that effect is more complex than the effects on other players by
backcounting. This page contains a series of Blackjack shuffle tracking
simulations to get a sense of the effect a shuffle tracker has on
the results of a card counter unaware that the shuffle tracker is
present. Six sims were performed. In each of the sims there are
two players: a card counter and a shuffle tracker. The card counter
always plays in the same manner. The shuffle tracker varies his
play and the counter's SCOREs are plotted as follows:
- I. Standard card counting, no tracking.
- II. Bad slugs are cut to the end of the shoe. Good slugs are
- III. Good slugs are cut to the top.
- IV. Good slugs are cut to the second deck.
- V. Good cards are cut to the third deck.
- VI. Good cards are cut to the second deck and bad cards are
cut to the end.
Remember, the SCOREs plotted in the chart are for the card counter
not the shuffle tracker.
- In only one case did the tracker negatively impact the results
of the counter. Sim III is slightly worse than sim I indicating
that cutting good slugs to the top has a very slight negative
impact on the unaware counter.
- Cutting good cards further into the shoe or bad slugs out can
have a dramatic positive effect on the unaware counter. Up to
64% SCORE improvement is seen in this particular set of sims.
- Get a tracker as a friend. :)
- This is hardly a comprehensive study. There are a huge number
of variables in standard Blackjack card counting simulations.
This is multiplied considerably in shuffle tracking sims. For
the purposes of this sim, only one shuffle and one method of attacking
the shuffle were used. Further, only one fairly tight dealer was
