Question: What is the name of the dealer typically employed by casinos who might work the game Blackjack Switch patented in 2009?
Context: Spanish 21 is a blackjack variant owned by Masque Publishing Inc., a gaming publishing company based in Colorado.  Unlicensed, but equivalent, versions may be called Spanish blackjack.  In Australia and Malaysia, an unlicensed version of the game, with no dealer hole card and significant rule differences, is played in casinos under the name "Pontoon".  It was first introduced into Nevada casinos in about 1995. Double Attack Blackjack is dealt primarily in Atlantic City casinos.  The game is a variation of Spanish 21 that pays even money on a blackjack and gives the player the opportunity to double their initial wager after seeing the dealer's upcard.  The game also offers a bonus side bet (called Bust It! , Bust out or Buster) on whether or not the dealer will bust on the third card.  This side bet must be made before the dealer's upcard is dealt, and pays out based on the rank of the card dealt.  The bet only pays off if the dealer busts on the third card, and the payoffs are as follows: In casinos, the term table game is used to distinguish games such as blackjack, craps, roulette and baccarat that are played on a table and operated by one or more live dealers like a croupier or poker dealer, from games played on a mechanical device like a video slot machine.  The term has significance in that some jurisdictions permit casinos to have only slots and no table games.  In some states, this law has made casinos host electronic table games, such as roulette, blackjack, and craps. A sail switch, vane switch or flow switch is a mechanical switch that is switched on or off in response to the flow or non-flow of a fluid such as air or water.  A sail switch typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it.  Sail switches find application in the detection of fluid flow and measurement of fan speeds.  A sail switch might be used to protect a central heating system electric heating element from being energized before the air flow from the blower is established.  Sail switches might also be used to alarm if a ventilation fan in a hazardous location fails and air flow has stopped.  For some HVAC systems, a sail switch can activate an electronic air cleaner, a humidifier, or other equipment in response to airflow from the system fan. A croupier or dealer is someone appointed at a gambling table to assist in the conduct of the game, especially in the distribution of bets and payouts.  Croupiers are typically employed by casinos. Double Exposure Blackjack (also known as "Zweikartenspiel" German: ""Two card game"" ) is a variant of the casino game blackjack in which the dealer receives two cards face-up in part of the initial deal.  Knowing the dealer's hand provides significant information to the player.  To maintain the house edge, the payout when the player receives a natural blackjack is reduced to even money from 3:2, and players lose their bets when their hand is tied with the dealer.  In addition, with both dealers' cards exposed at the outset, players cannot buy insurance or surrender their hand. Power Blackjack is a variant of the card gambling game Blackjack, modified by certain doubling and splitting rules, called "Power Double" and "Power Split," that are advantageous to the player, offset by the rule that, when the dealer makes a total of twenty two, any active player hands push rather than winning. Blackjack Switch is a casino gambling game invented by Geoff Hall and patented in 2009.  It is based on blackjack, but differs in that two hands, rather than one, are dealt to each playing position, and the player is initially allowed to exchange ("switch") the top two cards between hands.  Natural blackjacks are paid 1:1 instead of the standard 3:2, and a dealer hard 22 pushes all player hands except a natural. Elimination Blackjack is a tournament format of blackjack invented by Russ Hamilton, that was played on the Ultimate Blackjack Tour and in various casinos.  It combines the game of blackjack with elements of No Limit Texas Hold'Em.  Unlike Texas Hold'Em tournaments, players are still competing against the same dealer that is why the results of most players at the table are likely to be the same.  UltimateBet, a sponsor of the Ultimate Blackjack Tour, offered online elimination blackjack tournaments prior to bankruptcy. Gambit is an American television game show based on the card game blackjack, created by Heatter-Quigley Productions.  The show originally ran on CBS from September 4, 1972, to December 10, 1976, and was recorded at CBS Television City in Studios 31, 33, 41, and 43.  On October 27, 1980, NBC revived the show as "Las Vegas Gambit", as a replacement for "The David Letterman Show", and kept it on its schedule until November 27, 1981.  As the title implied, this edition of "Gambit" was recorded in Las Vegas with the Tropicana Las Vegas, which had previously hosted "Dealer's Choice" and later hosted "Let's Make a Deal", serving as the show's base.  Both versions were hosted by Wink Martindale and announced by Kenny Williams.  Elaine Stewart was the card dealer for the CBS version, while Beverly Malden filled this role for the first half of "Las Vegas Gambit", and was later replaced by Lee Menning.
