No, not that Don Johnson, but an interesting fellow all the same. Businessman Don Johnson is noteworthy on account that he took the casinos for millions (over $15 million in fact) playing Blackjack, but without using the ubiquitous card counting technique.
His winning streak occurred during 2011 – 2012 and pertained to an agreement with the casino that it would be allowed only a 0.26% edge. He then negotiated a separate loss rebate deal that pushed the edge slightly in his favour.
It was in a sense more of a ‘hack’ or loophole’ based on mathematical chance, and probably isn’t something that would work today in the more sophisticated casino environment. It certainly worked for him back then though, and he was rewarded handsomely for his efforts.
