Ask the Wizard: Blackjack (multiple hands & players)
Multiple Hands & Multiple Players
Every time I go to the Blackjack games there is a grumpy simple individual, who wants to stone some poor soul for "messing up the shoe.” Is there any truth to this? — Jim from Las Vegas
In ten years of running this site I steadfastly denied the myth that bad players cause other players to lose in blackjack. However, you are the lucky 1000th person to ask, so I took the trouble to prove it by random simulation. The rules I put in are the standard liberal Vegas Strip rules as follows.
6 decks
Dealer stands on soft 17
Double on any first two cards allowed
Double after split allowed
Late surrender allowed
Player may re-split to four hands, including aces
Cut card used
First, I had both players follow correct total-dependent basic strategy. Over almost 1.6 billion rounds, the loss of the first player to act was 0.289%, and the second player to act of 0.288%.
Second, I had the first player follow the same correct strategy, and the second player follow the same correct strategy except:
Always hit 12 to 16
Always double 9 to 11
Split any pair
Never surrender
Never soft double
In a simulation of 1.05 billion hands the loss of the first player was 0.282%, and the second player was 11.260%. So the house edge of the basic strategy playing first player was almost the same, regardless of whether the second player played correctly or wildly incorrectly. I hope this puts and end the third baseman myth, but I doubt it. As I have said many times, the more ridiculous a belief is, the more tenaciously it tends to be held. June 19, 2007
I'm very glad to see that you are back changing the world 1 mathematically challenged emailer at a time. I have a combination of a dear abby and an odds question. Here goes: A coworker of mine has gone his entire gambling life getting angry at the 3rd base player in blackjack whenever that player doesn't follow basic strategy. He insists that that "bad" player is hurting his odds. I am 100% certain that it doesn't change your odds at all. I have tried to explain to him that the reason he thinks it hurts him is because the times that it has in fact hurt him stand out in his mind, and he probably doesn't even pay attention to the times that it helped him. I told him that mathematically, his odds are the exact same whether he plays at a table of people who never hit, a table of people who never stay, or a table of people playing perfect basic strategy. He doesn't buy it. But, how can I possibly convince him that he's wrong? Should I even continue to try? If he admits that he's wrong, he has to admit that he has wrongly berated countless people at blackjack tables when those people were not hurting anyone else but themselves (and in some cases, if they were counting cards and adjusting their strategy accordingly, they weren't even hurting themselves). Don't you think casinos would be better places if people really understood that what I do with my blackjack hand doesn't change your odds in the long run? - Aaron from Detroit, MI
Your coworker sounds hopeless. As I have said before, the more ridiculous a notion is the more tenaciously it tends to be held. I'd give up on him and let him believe in his delusion. Personally I don't give unsolicited gambling advice because it is seldom well taken.

What advantage if any does the house have when using a
six spot layout verses a 7 spot layout? - Steven Ritondo
from Margate, USA
They can deal more hands per hour in a 7-spot
game. However the advantage per hand is the same.
Personally I hate these 7-spot tables.

Why do land casinos make you bet more when playing a
second hand in blackjack? When playing on line is there an
advantage when playing two or more hands? - Brian Crouch
from Independence, USA
I think the reason for this is that they don't
want a minimum bet player hogging up two spaces. This
will slow down the game and possibly prevent bigger
bettors from playing. Not all land casinos have this
rule, I think it is more prevalent in Atlantic City,
where tables are more crowded, than Las Vegas. Whether
online or a land casino there is no advantage to playing
more than one hand. Nov. 28,

My friend and I are debating two blackjack issues that
arose from his Caribbean Vacation. (1) What shift in odds
does the dealer NOT drawing the second card have? House
favor or player favor? (2) in your simulations, what impact
does the number of players have on the accuracy of the odds?
- Beau Richards from Toronto, Canada
(1) It depends what happens if the dealer does
have a blackjack. If the player is guaranteed to lose no
more than the original wager then it doesn't matter if
the dealer takes a second card or not. If the player
stands to lose the total amount bet after doubling or
splitting and the dealer gets a blackjack then that works
to the dealer's advantage. (2) I don't have to simulate
this because the number of players makes no difference.

In blackjack and/or in Caribbean stud poker, does it
make a difference if you are the only player seated at the
table versus if the table is full? - Patrick from New York,
USA
No Feb. 11,

In the game of blackjack, can you tell me if people
entering and leaving the game changes your odds of winning
or losing? It seems to have an effect when I am playing. -
Jerry Shafer from Shreveport, USA
No, other players entering and leaving will have
no long term effect on your odds. This may seem to be
true but I suspect you are more likely to remember when
entrances and departures hurt you than the times they
helped you. In the long run the cards are the cards and
all other factors cancel each other
out. July 18, 2001
I notice that some internet Casinos give you 2 cards
right away one on each hand before you begin to play each
hand, unlike a live casino which play the split, one hand at
a time. Is this a house advantage dealing two cards before
beginning play on the split hands? - Karter from Calgary,
Canada
Mathematically speaking it doesnít make
any difference. Jan. 20,

Do you change your strategy based on the play of other
players at your table. For example, you have players who hit
when the dealer has a bust card face up taking the bust
cards and therefore the dealer does not bust. ñ Star
from Ft Worth, USA
As a card counter I do care what cards come out
but I don't care how other players play. Actually it is
slightly to the advantage of the card counter when the
other players hit excessively in a single deck game,
where the dealer plays a certain number of hands and then
shuffles. The reason is that the cards are then dealt
further into the deck. Dec. 10,

Do the odds at table games change when the number of
players change? In other words, if there are more hands
dealt, do the odds change? If not, is there anything at all
salient (odds wise) about the number of players partaking in
a particular game? This will settle a "bet". - Steve
Meredith of Detroit, USA
Generally, no, the odds do not change depending on the
number of players. The only exception I can think of is side bets like Fortune in Pai Gow Poker, which feature an envy bonus, and thus pay better according to the number of players. Nov. 4,

Q: Is there any mathematical proof you can provide
that will prove a player sitting at "third base" on the
blackjack table can't change the outcome of the game by
making bad decisions based on "basic strategy" I have had
many people argue that poor decisions at third base, or
anyplace on the table for that matter, cost them money. I
would love to see the actual numbers on this if it is
possible. Great site by the way. I love gambling, and your
site is one of the best I have seen on the web. Actually has
real proven info. - Mike Castelluccio of Lafayette,
U.S.
A: Thanks for your kind words. Unfortunately I do not
have any such proof at hand. If I did set about proving it
myself I would use a computer simulation. However skeptics
would probably claim something ridiculous, like that bad
players disrupt the karma of the game, which can't be
replicated in a computer. Aug. 13,

Q: In blackjack, do you improve your chances by
playing two hands at once for x each, versus 1 hand at a
time for 2x? If the odds are better, how much better? - Jim
of Atlanta
A: The simple answer is no, it neither helps you nor
hurts you. However you will have less bankroll variance by
betting two hands of x as opposed to one of 2x. Card
counters are an exception to the simple no, they may play
multiple hands to draw more cards out of a deck rich in good
cards, thus improving their odds.
