You find value by identifying an underestimated team by public opinion. It means everyone is talking negatively about that team, but you see a potential there others can't see, because they are blind by their own ignorance or by specialists' guesses. Then you bet on that team against all the probabilities and win a decent prize.

It can be that the team you picked has young and unknown players yet, but you know they are developing their careers fast, and can suddenly surprise the public. Or it can be that the rival team is facing some difficulties with determined key players or even the coach, so you bet against them aware about their current situation.

There are different scenarios you can take advantage when placing your bets in sports.
