Experience in betting and analysis of the upcoming game are of course important for a player who bets on the victory of one of the teams. If these are not fan bets, when a player bets only and exclusively on his favorite team, then sometimes it is probably worth weighing the risks and betting against the public. And sometimes it happens that this is an excellent decision and the bet wins. I would also draw attention to the pleasure that a player gets who bets against the public and wins.
This clearly increases both self-esteem and pleasure. And in general, this is an interesting version of the game, but of course you should not abuse such bets.
The thing is when he want to place a bet, he need to analyze everything so he will know how big the chance for him to pick the team that he thinks will win. He can choose betting against the public or betting following the public based on his analysis because his reason to place a bet is to win the match. Maybe he can choose betting against the public because he see the chance to win on that. But all in all, he must know about the risks when he pick one of those so he can prepare and accept whatever will happen later.
