How
Much Money 

To guard against
going belly up?" Without presenting all the
numbers and fanfare. let's answer those three questions
one by one.
If you're headed to the casino for a three or four
hour playing session, 60 of your average size bets
will cover you the vast majority of the time. That
means if you're spreading your bets from $10 to
$100 and averaging about $20 per hand, then $1200
(60 x $20) is a solid playing stake for the day.
If you'll be vacationing in Las Vegas for a week
and think you'll put in maybe 25 hours at the Online
Blackjack Games tables, then 150 average bets should
keep you in action throughout your trip. Again,
betting $10 to $100, that would take $3000 of your
hard earned money.
How about the long run? Somewhere sometime, you'll
probably go on a killer losing streak lasting hundreds
of hours and dump off 400 average size bets in the
process. At $10 to $100 a shot and a $20 average
bet, you'd better have about 500 bets, or 10 G's
stashed in a strongbox somewhere for a rainy day.
Square Root Rule: There's a handy rule of thumb
that can help you determine your required bankroll
for various periods of time at the tables. You see,
your standard deviation, or volatility runs directly
proportional to the square root of the length of
your play.
For example, let's say you've learned that you need
$1000 to play comfortably for 4 hours on any given
night. Then how much do you need to play the same
stakes for 36 hours when you go out of town next
week? The answer would be $3000. Why? Because the
square root of 36 hours (which is 6) is three times
as big as the square root of 4 hours (which is 2).
With those two amounts of money, you'll have the
same chance of going broke in both scenarios 
if you're a break even player. If you're an overall
winner, you're requirements will rise a little more
slowly than that as the hours mount. If you're a
loser, they'll rise more sharply.
If you're not a math geek and don't want to mess
with square roots, then just use the following chart
as your guide. It summarizes your practical bankrolling
requirements for the night, for the trip and for
the long haul.

Classic
Poker Style Archetypes 

By
combining the labels, you can place everyone into
one of four groups: loosepassive, looseaggressive,
tightpassive, and tightaggressive.
Although
you will find those experts who insist on subdividing
the poker population into many more subcategoriesnot
an unreasonable position because there are many other
kinds of groups into which you could divide the poker
population, such as analytical vs. intuitivethere
are only so many labels one can apply before the number
of labels creates an impractical learning tool.
Let's
examine these four subgroups. Later in this section
and in the upcoming chapters, we'll look at personality
traits that tend to create the individual styles.
