pages 126-130 the volatility of Double Exposure and
Early Surrender Online Blackjack Games is described.
The large magnitudes of the effects of removal of
different cards with these rules resulted in much
faster changes in advantage than in ordinary Online
Blackjack Games. A natural consequence was that casinos
took bad beatings in each of these games: early surrender
is not likely to reappear except by occasional and
temporary mistake, while the rules for double exposure
have been greatly restricted so that there is little
current interest in the game.
Two other variations in the rules which do remain
common are worth discussing in the context of their
impact on the volatility of player advantage. Compare
the following figures with those on page 44.
if doubling down after pair splitting is permitted,
the major changes are greater effects for removing
a 4 or 5 (by +.02) and a ten (by -.0l). Thus this
rule also results in slightly greater volatility.
The effects of removal on the Online Blackjack Games
bonus quoted in Appendix E, page 202, would also apply
in the 2 to 1 Online Blackjack Games payoff giveaway
at Binion's Horseshoe in Las Vegas the iek before
Christmas: to the effects above, for dealer hitting
soft 17, add -.49 for an ace, -.06 for a ten, and
+.09 for all the others.
players tend to learn how to avoid them, but they
still happen and when they do, players guard the secrets
like gold. You don't even tell your friends. I have
a tell on a very famous player and he has a very hard
time with me, even though he's a better player in
the abstract. I usually know when he has a strong
hand, and so would rather see him at my table than
someone with a tenth of his talent. If you have consistent
trouble with someone, especially if he's someone you
can't ever bluff successfully and/or can't get to
"pay you off' when you have a big hand, there's
a good chance he has a tell on you.
