Parmesan, a 56-year-old man whose real name is Stefano Ampollini, then used infrared contact lenses purchased online for 2,000 euros from a Chinese company to read his competitors' hands.

The casino's lawyer told The Telegraph that "security found his behavior rather strange as he won very easily and, above all, because he folded twice when he had an excellent hand, suggesting he knew the croupier's cards." As with other schemes, it's one thing to figure out a way to beat the house. It's quite another to replicate that success without raising alarms in casinos with complete surveillance.
