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?
Analyzing both teams and betting on the team that I find better would be my way to find value.
Like what you said, it's impossible to analyze every single game available for betting so what I'm doing is that, I'm trying to bet on a single sport (which is basketball), will try to learn the teams around it, and make myself updated on what's happening with different teams so that analyzing would be much easier.
Limiting the number of bets or making "WELL-STUDIED" bets will not guarantee us the win if we are betting especially on sports. I don't know if it's just me, but we know that there are some games where we expect that Team A will win because of how good the players are, or there are some that are injured or whatever factors it is, but the opposite will happen. This is rare, but we know it's happening. This is the reason why I find analyzing both teams a bit useless because of these scenarios, but I'm not saying that it isn't helpful at all.
