I read an article that says in order to win in sports betting in the long run, we need to find value before making a bet. This means we don't need to bet on all the games available because we can't find value in all of them. Since it requires careful analysis based on the information available, it's impossible to analyze every game available for betting. Therefore, it's important to limit the number of bets and make sure that all the bets we make are well-studied so we can come out ahead in the long run.
If you believe in this, from your personal perspective, how do you find value?
I don't know how to find value, but I agree with reasoning mentioned herein.
You can't make a good bets on matches/sports you have no idea of. Stick to matches you are interested in, you have idea of teams, players and importantly you like to passionately keep track of particular sports and that'll automatically result in you making successful bets.
