Context: Frank Scoblete (born 1947) is an American author who has written both under his own name and King Scobe about casino gambling.  Referred to by the "Washington Post" as "a widely published authority on casino games," his books include "Beat the Craps out of the Casinos", "Golden Touch Blackjack Revolution," and "Beat the One-Armed Bandits".  He has written and appeared in television documentaries such as the "What Would You Do If ...?"  program on The Travel Channel, written numerous columns for gambling magazines and websites, and produced a series of videotapes and DVDs, with most of his work being about the games of craps and blackjack. 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. 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. 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. 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. 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. 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. Arnold Snyder is a professional gambler and gambling author.

He was also the first blackjack researcher to publish (in "Blackjack Forum", 1981–1983) that radical simplification of blackjack card counting systems did not hurt earnings.
