people aren't usually so sharing with their strategies specially if they work. besides there aren't any strategy that can always work and is fool proof. some people get lucky with a strategy for a short while and thing that is a golden strategy until they lose and give up.
There is nothing that is actually fool proof. Everything is actually fool proof unless proven otherwise and people are just nuisance to think it that way . People should be reading the title of this thread, everyone looses in the long run and that totally tells everyone that there is nothing that works in gambling unless variances are on your side and you win
