Quote from Pekelo:
That doesn't mean he didn't have some other skills or strategy.
I think in a way he was lucky, since if you martingale, your streak will eventually run out and the numbers will catch up to you, as jrlvnv's story showed.
My best guess (and why the casinos allowed him to play for months) is this:
1. He was martingaling.
2. He had a big bankroll that allowed him to do so.
3. He had the balls/willingness to play big and keep averaging down.
This article explains that he took Ceasars down 3 times, and they still allowed him to play. I assume they analized his play, figured out what he was doing and they knew the strategy eventually will bust. This way Johnson indeed was lucky, that he never ran into an extended period when the cards were against him.
âBy Johnsonâs account, he won $4.23 million at Caesars Atlantic City in December. Next, he conquered Borgata Hotel Casino & Spa, winning about $998,000 in December, then $1.8 million in March and April and $2.25 million over two nights later in April. Most remarkable was his haul of $5.8 million during a 12-hour spree at Tropicana Casino and Resort in April, a record loss for the casino."
This would explain why nobody other did such a feat before. Most blackjack pros don't have such a huge bankroll, don't play such a high stakes and even if they do, they don't have the willingness to play such a strategy....
