Dear Mark,
Could you please explain the physical process of shuffling that casinos use in
blackjack? Also, why when a new deck is brought in, do some casinos place them
face down and swish them around like we did as a kid when playing the game of
Fish? Richard C.
Casinos differ on shuffling procedures used to prepare a deck or decks for
continued play. They may include "riffling" or "stripping"
the cards as well as "washing," "plugging," "boxing"
and other idiosyncratic techniques. The ultimate goal, when a dealer shuffles
up, is to achieve some level of randomization in the order of the cards. I'll
discuss the three most commonly used shuffling methods used in casinos today:
Riffling, stripping and washing the cards.
Riffling the cards is the most commonly used shuffling technique used on all
casino card games. To accomplish a riffle, the deck is divided roughly in half,
then the dealer will pull the card corners up with the thumbs and let the two
halves "riffle" together, interleaving the two halves into a solid
deck. Sometimes called "zipping" the cards, riffling a deck can range
from a fine riffle to a coarse riffle. Dealers usually riffle the cards between
three and five times before dealing the next round.
Stripping is a shuffling technique that reverses the sequential order of groups
of cards in the deck. Say for instance a dealer took the first card off the
top of a deck and placed it on the table, and then took the second card off
the top and placed it on top of the first card. Continuing this process through
the entire 52 cards would exactly reverse their order. This characterizes the
basic process of stripping.
Dealers don’t strip cards one at a time, but instead they rapidly pull
small clumps of cards off the top of the deck, actually altering the order of
cards in the deck. The number of cards in the clumps determines how fine or
coarse the stripping process is. Stripping the deck is a procedure that some
casinos make their dealers employ before riffling the deck.
Washing, per your Fish question, where cards are placed face down and fanned
out to form a stock, is where the dealer spreads the cards on the table face
down and then proceeds to commingle the cards in a washing-like motion before
collecting them up and performing a more conventional riffle shuffle. Card washing
is intended to remove any consistencies in the sequencing of the cards, and
are typically washed, Richard, when new decks are brought into a game.
Dear Mark,
I sat next to a player who began with $100, and over a three hour period had
won over two thousand. Then his luck turned and he lost it all in under 10 minutes.
What makes a player give all his winnings back? Bud W.
In the poker world, Bud, it’s called "going on tilt." In blackjack,
we call it "steaming." Either way, it's when a player loses emotional
control of his game and starts betting more aggressively, often impulsively,
in an attempt to turn his bad luck around. I’ve seen this reckless conduct
far more often than you can imagine, that of a player trying to spin straw into
gold, only to become so frustrated with how poorly his playing session is going,
that he losses his entire bankroll in mere minutes. Canny players avoid that
fate by setting and sticking to loss and gain limits.
