Don't get offended by my words but do you think that you are the smartest of all bettors to have thought about this alone? Obviously, a very successful gambler don't always have the patient to hold back publicizing their success and the strategy they used to achieve it, you can do your research about it and you will not read any where that there's a very successful gambler that had a hidden have been printing money for them from gambling. Many gamblers and bettors have tried different methods and strategy but non have been confirmed to work frequently,  if you think this is going to work, try it with just two teams which you literally know their match too well.
