once before...
the randomness of the 21 game was attacked by technology.
when the mikohn "track-jack" was debuted at a gaming show, i carefully observed the demonstration and sales presentation to industry attendees. the dealer/mikohn rep exactly stated that one of the benefits of the system, beyond evaluating a player's worth, was to alert the pit when the deck "was out of line". read, "plus" count. the particular monitor demonstrated could display the "count" on several games simultaneously. when the count went up on a particular table, the screen background could change color on that split screen window, thus alerting the pit game supervisor ('stiff) that the game was vulnerable. since there are no rules regarding early shuffle-ups on even shoe games, it's obvious that beyond "protecting the game", a 'stiff directed, early shuffle-up [breaking a shoe], absolutely is designed to stifle the randomness of the game. and that, is illegal. altering the randomness of the game is a ticket to the crowbar motel, when performed by a guest/player. apparently what's sauce for the goose is *not* sauce for the gander.
i forwarded this info along with the supporting sales literature to arnold snyder. sometime later, i noticed that snyder was a participant on a gaming discussion panel which included at least one mikohn staff member. snyder pointedly asked if the system could/would/might be used to detect card counters [to alter the randomness of the game]. as i recall, at least twice the mikohn rep denied that the system could/would be so used. that was exactly a lie since that was contraty to their sales employees' presentation.
