How do you determine what you're going to bet on? I realize some bet on their favorite team or the team everyone else is betting on or maybe what an "expert" tells them. For example, look at college basketball. Some nights, there are 20-30 games. A few days ahead, do you just scan for team matchups that look promising and then as the odds are set, if they look good, you do your research and make your decision? Up until now, I sort of look to see what everyone else is doing and then I do some research to back up the decision. I'd really like to progress to the next level. Just trying to figure out what my next step is.
Any insight is appreciated.
