Tynan,
Interesting read. Thank you for sharing your story with us.
I don't doubt the credibility of what you say, particularly since you know the Martingale system is ultimately flawed.
I would be interested to know, however, whether if any of your professional gambling exploits have been on land based casinos? Both of the books you mentioned involve APs exploiting land based casinos.
Finally if you enjoyed those two books, I would also recommend Repeat Until Rich by Josh Axelraad. It's a great read.
Best Regards
Jasper
