I've been using this method but it does not give me a success, you cannot just pick blindly and just bet against the public since there are a lot of factors to consider. For example, if you are betting on a shitty team which they are not the favorites all the time you will lose your money easily and also you cannot bet against the warriors because they are good in covering the spread. I would bet against the public but I need to be choosy and not just bet on all the games on the board.
maybe better to play with this just to have some fun but not a serious gambling, playing against the public really good if you got some success with the
timing, its luck that will give you some decent earnings when pick the under dogs and happen to win in a regular bet not in the handicapped.
