Of a truth sometimes, I don't even check the team that I pick, all I do is to just follow the team that have the highest odds and allow my risks and greed to have the better part of my thinking, whenever I am betting in this line, I make sure that I bet with the amount of money that I am ready to lose, somewhat a small amount.
Going with the highest odds might not be a perfect choice since favourites win most of the time. It will be better to do a proper analysis before placing bets. Taking risks and going for impossible games might be beneficial sometimes. A clear example is the FIFA Club World Cup tournament final that was played yesterday. Chelsea had high odds because many analyses showed that PSG were clear favourites. But those who dared not follow popular perception won big yesterday.
And for sure those who bet against the heavy favorite managed to cash out decently, not always but the feeling of enjoyment when somethin like this happen to your bet that's adds up to the pleasure that you gain when you are inside gambling, though those who chase for the same bets over and over might at risk, as for sure not every attempts will go on the same outcome.
Most of the time, favorite wins and a matter of timing and good analysis of the game may give you hint that underdog might pull the trigger and upset their opponents.
