Finding Value Bets (know your sports, study hard, money management - basically being a pro!)
This is what I do. It is not as easy as it sounds but I am able to make some profit since I am fun of football and know which team to bet on.
It is a little profitbut at least am having more fun when watching football matchs.
Good on you! Value betting is for the purists

And, like you say, having made a judgement yourself makes it even more fun when you watch the match.
