Very simple logic is this, if there is a ' confident method to win', who would need to work?
Even if there is, it would be more of a system/rules flaw which would quickly be detected by SP and corrected LOL.
This SP entity is created by the Gov to legalize gambling and make money from punters, not the other way round.
Just like casino, once they detect some loophole resulting in them losing money, either you will be banned from betting or the loophole will be quickly corrected.
