Dustin Marks is, without question, one of the most successful blackjack cheaters in history.  

Possessing an uncanny ability to remain calm under pressure and the talent to perform undetectable sleight of hand under fire, he was employed as a blackjack dealer by several well-known casinos in Las Vegas during the 1980s.  

While under the watchful eye of casino surveillance systems and pit bosses, he beat the casinos and WAS NEVER CAUGHT!
