Index Lesson 18:
Advanced Single-Deck Blackjack, Part 1
While much of card-counting is a science
-- the science of mathematics -- it all takes on something of
an art form when playing at a single-deck game. True count conversion
is difficult to do quickly, large bet spreads (over 4 to 1)
are difficult to obtain and it's hard to keep an accurate count
at a game which is dealt face-down when you're used to counting
where all the cards are face up. Despite that, I really urge
you to learn how to play single deck and, instead of banging
your head against the multiple-deck games in your area, save
your money and take 2 or 3 trips to Reno each year. No, I'm
not in the employ of the Reno Chamber of Commerce, but I can
tell you that it's a great place to make $$$ at the Blackjack
tables, it's relatively inexpensive and typically very easy
to get to from all over the United States. Sure their rules,
for the most part, suck (only double on 10 and 11, no double
after split and the dealer hits A-6) and that gives the casinos
the same .5% edge off the top that you're fighting now, but
it takes just one +1 card to get you even with the house and
that's the real appeal of single-deck. I should mention that
some casinos in Reno (as well as in Tahoe and Laughlin) allow
double on any first two cards, so the casino edge is dropped
to about .2% and that's a very beatable game.
The key to evaluating good single-deck
play is how many cards you'll see before a shuffle. If you can
find a game with 60% penetration and get away with a 5 to 1
betting spread, it's fairly easy to obtain a long term winning
rate of 1.5% of all the money you bet, just by playing basic
strategy and varying your bets according to the count. If you
also modify the play of your hand according to the true count,
a win rate which approaches 2% is possible. That's serious money
Blackjack fans, so the effort is worth it.
Which Counting System?
I use two different systems for counting
cards; the Hi/Lo for multi-deck play and the 'Hi-Opt 1' system
for single deck play. The latter counts 3-6 as +1; 7,8,9 and
ace as 0 with 10s as -1. Since there are only four aces to track
in a single deck game, I find omitting the ace in the count
improves the play of the hand, yet I can still 'adjust' the
count for betting purposes. Let's talk about a side count of
aces for a moment. We expect to see one ace per quarter-deck
played in a normal distribution, but of course that doesn't
always happen. For example, if a quarter deck has been played
and no aces have come out, the remaining deck is 'rich' one
ace. I can -- for betting purposes -- temporarily add +1 to
the count, yet for playing purposes the true count without adjustment
is correct. Got that concept? If a quarter-deck has been played
and 2 aces have come out, the remaining deck is 'poor' by one
ace, so I would lower the count by 1 (that is, 'add' a minus
1 to the count ) just for betting purposes, since my opportunity
to receive a natural has decreased. This is a very powerful
addition to your game, but my advice is to just use it in single-deck
play because an ace adjustment is very taxing, mentally.
If you want to learn the Hi-Opt count,
use the same techniques I showed you for learning the Hi/Lo
count. All of my advanced techniques will, however, be based
upon the Hi/Lo system, since that seems to be the method most
of you are using.
The most difficult aspect of single-deck
play is computing the true count. First you must 'calibrate'
your eyeballs for measuring the number of cards which have been
played. Today most casinos have the dealer place the discards
in a rack to the side; unlike the 'old' days when they put the
discards underneath, so deck estimation is easier. The really
tough part is the division which is required. In a multideck
game, we're almost always dividing one wholre number (the running
count) by another number which is at least 1. Admittedly, some
people have a problem of dividing 17 by 2.5 qucikly, but it
doesn't take long to get used to. In single deck, you're always
dividing by a fraction or decimal and that's not easy. For example,
if you're at a single-deck game and a quarter-deck has been
played, with a running count of 3, the true count is 3 divided
by .75 = 4. That's actually an easy example. Try dividing a
running count of 5 by .5. The answer is, of course 10, but how
many of you wanted to say 2.5 or 1? Only practice will make
this an automatic process.
Homework
Continue learning the decision numbers
for Hi/Lo basic strategy variations in the multiple deck games.
For the 'overachievers' out there,
start learning the Hi-Opt 1 count.
