Commercial systems employing so called "true
counts" (defined as the average number of points
per card multiplied by 52) produce both types of error.
The estimation of the number of half decks or quarterdecks
remaining is necessarily imprecise: with 20 cards
left unseen some might divide by 1/2, others by 1/4.
The relative error in the presumed parameter could
thus be six or seven tintieths, 30 or 35%. Published
strategic indices themselves have usually been rounded
to the nearest whole number, so a "true count"
full deck parameter of5 might have as much as a 10%
error in it. it is the view of the salesmen of such
systems that these errors are not serious; it is my
suggestion that they probably are.
to another table at the same limit is an entirely
different procedure. When they have more than one
table at the same limit, cardrooms keep a list of
players who want to change tables, but the actual
procedures for doing this vary widely. In some cardrooms,
one of the tables is designated as a "must move"
table. If table two is a must move table, then whenever
a seat opens at table one, the player who has been
on table two the longest must move. New players are
always seated at table two. If the cardroom you play
at designates must move tables, then you'll probably
have to negotiate something with the other players
if you want to move before your turn.
In cardrooms that don't designate must move tables,
changing to another table at the same limit is still
not a standardized procedure. Some rooms keep a formal
change list to allow players already seated in a game
the option of taking a new seat when one opens up.
In most cardrooms, however, the brush will rely on
his memory to maintain a change list. Especially if
they are busy enough to have more than one table at
the same limit, you can count on the brush's memory
being faulty. You'll have to maintain some vigilance
of your own to make sure you are allowed to move to
an open seat-once a new player has been seated it'll
be too late. One of the benefits of playing in large
cardrooms is that there are often other tables available
for a change. When you're seated at a table, always
ask the brush to put your name on the change list.
You should keep yourself on the list for other limits
within the range you're comfortable with. Pick a good
table and be prepared to change when the conditions
