In true Dragons Den style, I'm out
I don't feel qualified to advise on gambling methods. I'm neither for or against gambling per se but this site is all about making money from bookies without
any risk, so personally I don't see the point. I'd rather make money than take risks.
I'm not sure if you're describing betting on every possible outcome ie team a, team b and the draw; in which case you'll lose out due to the bookies building in their guaranteed profits - the overound I think it's called.
