Double Exposure
Last update: Oct. 23, 2009
Introduction
Double exposure is a
blackjack variation in which both dealer cards are exposed.
Naturally there are other rule changes that favor the dealer
to compensate. Although the house edge is greater than
conventional blackjack, it still ranks as one of the best
bets in the casino, if played properly. If you can find the
game, this section will tell you how to play it.
Rules
The usual rules are the same
as blackjack except:
- Both dealer cards are
exposed
- Dealer wins on all ties,
except on a natural blackjack
- Player blackjack pays
even money
- Player may split only
once
Rules that can vary include
but are not limited to:
- Dealer hits or stands on
soft 17
- Tied blackjacks either
push or go to the player
- Player may or may not
double after a split
- Player may double on any
first two cards or not
- Player may split more
than once
- Player may or may not
split unlike 10 value cards (for example queen and
king)
Following are some actual places that offer or have offered double exposure, the specific rules, and
house edge. Sometimes the game goes by other names like "Dealer Disclosure" or "Face Up 21."
