I agree with you, there is an article or a video or something that explain the interview with an old Las Vegas casinos player was once asked, what is the best way to profit in a casino games, he respond was quite outrageous and abstract. He said " To profit greatly from casino in Las Vegas is to get the ability to find the nearest exit from the casino hall"
That if getting through that exit door is always easier for you, then you've won greatly.
This answer is like telling someone to go to ocean and look for every possible way to drill everything because that is how impossible his answer looks, he is very technical to come up with such answer because is the kind of response that usually gets people to start looking at each others to no if they had an idea of what he is actually talking about, if you ask me I would say the question was not necessary because nobody will tell you about there secret especially when it has to do with gambling and if he does then everything is lost for him, the ability of not knowing the mind of the bookies is the fund people derive from gambling.
