In the 1980’s two crafty blackjack players managed to find a way to win that it’s as simple as it was effective. The players (John Dixon and Robert Ailse) would sit side by side and switch one or their cards in order to make the best possible hand. This of course alongside strategic staking ensured that defeating the house edge was a simple formality.
To decrease their chances of being found out, the pair also had others involved in the scam, standing in strategic positions in order to obscure others seeing the card swap take place. To this day, it’s not known how much money this scam earned the pair.
