edge sorting. A technique used in advantage play where a player determines whether a face-down card is likely to be low or high at casino table games by observing and exploiting subtle unintentional differences on the backs of some types of playing cards. The player must persuade the dealer to cooperate by unwittingly “sorting” the cards into low and high.  This practice of card sorting is referred to as the “the turn”.

element of ruin. The likelihood that a player or team of players will lose their bankroll. Usually expressed in percent form. In 1981, Ken Uston wrote that his blackjack teams always used a 5% element-of-ruin, which meant that his team’s bets were calibrated to yield a 19-out-of-20 chance of doubling a bank and a 1-out-of-20 chance of going broke.

end play. {CS}. A strategy that can usually be executed only in the last few cards of a deck. As most card counters know, the deeper a dealer deals into the deck or shoe the more accurate measure a player’s card counting system will be. Nearly all casinos cut out some of the cards at the end of a deck or shoe to prevent knowledgeable players from using this very profitable strategy. End play is the method of forcing the dealer to run out of cards and thus requiring the dealer to deal the rest of the round from the shuffled discards.    See cut card.

Error !errors. Errors can be made by the dealer or player.   Common errors that dealers frequently make and that may be exploited by sharp players include the following:

  • Not paying attention to game
  • Giving double-down card before additional money was put in circle
  • Paying pushes
  • Not collecting lost bets
  • Placing change in betting circle
  • Flashing the hole-card
  • Flashing the next card
  • Flashing the burn card
  • Failing to check limit bets
  • Incorrectly adding card values

Depending on where you play, mistakes in payoffs can be common, especially if the dealer is tired or the dealer is a novice. This author estimates that dealer errors may contribute to as much as 0.05 – 0.2% to a player’s overall advantage in the game. Of course, this estimate assumes that the player catches all those mistakes that a dealer might make that would favor the player.  In this author’s opinion, player errors are the greatest contributor to the downfall of most card counters.

According to Peter Griffin, there are two types of error in employing a card counting strategy.  One has to do with an inaccurate running count / true count conversion.  The other has to do with an imprecise knowledge of the proper critical index number for changing strategy.

European rules. 1) (ENHC, NHC) Also referred to as no-hole-card rules. This is a reference to the rule (as seen in many European casinos) that requires the dealer to wait until after the players have played out their hands before taking a hole-card. This, in itself, is not a reason to change basic strategy, however, since the dealer also keeps all double down and split hand bets if he has a natural, a variation to basic strategy is required. See basic strategy section.   2) In general, the following rules apply in many European countries:

  • All 6 or 8-decks games.
  • Double on a 9, 10, or 11 only.
  • European no-hole card rule.

Some casinos allow double after splits and re-splitting of pairs and others do not.  See OBO.  See OBBO.   See BB+1.

EV. Acronym for expected value.

even money. A phrase that the player may state or the dealer may ask, if the player has a blackjack and the dealer has an ace as an up-card. If the player agrees to even money he will be paid the amount of his wager before the dealer checks his hole-card. This is essentially the same thing as the player insuring his blackjack. Like insurance on any other hand, you should not take even money unless you are counting cards.

EW. Acronym for expected win.

Exhibit CAA.  See Beyond Counting by James Grosjean.

expectation.  The theoretical outcome per wager and a measure of how much the player (or casino) can expect to lose (or win) in a particular game based on the handle.  This measure (generally expressed in dollars or percent) is based on the player’s statistical advantage or disadvantage.  An example of expectation for a fixed game such as American roulette would be -5.26% for a 1-unit wager on black or red. See expected value below.

expected value. (EV) 1) Same as expectation and often used interchangeably with the term advantage. 2) Same as expectation but including the additional value from comps earned during play.
[ Expected Value of an Advantage Blackjack Player ]

expected win. (EW) Same as expectation but generally a representation of X dollars per X number of hands.

Card Counters Raise HavocExperiment. aka “The Experiment” or “The Early Surrender Experiment”. A reference to the 13 day period (January 16-30, 1979) when Resorts International Casino in Atlantic City offered early surrender and card counters could play unhindered at their blackjack tables.  It is reported that several teams took advantage of this rule including the Czech team, Ken Uston’s team and Tommy Hyland’s team.  Later that year, on December 1st, the New Jersey Casino Control Commission ordered all Atlantic City casinos to permit card counters to play blackjack again.  Thirteen days later, the rule was rescinded again.  See Black Tuesday.
