How do I choose my selection?
You're looking for bets where the implied probability is less than what you actually think is going to happen (your predicted probability). Remember, the sportsbook pays you out based on the likelihood of something happening. The less likely it is to happen, the more money they are going to pay you out.
To choose a game to bet on, it is essential that you know the competition to which it belongs. Each competition is unique, and the more information you have, the greater your chances of success.
In order to bet in an organized and assertive way, criteria are necessary, knowing how to choose which bets are interesting and which are not is a fundamental step towards success. It bears repeating: the more you know about what you are betting, the more chances you have of becoming a successful bettor.
