very rarely against the majority because the risk is very large, in certain matches for example many people who like a team that is known to always be able to win a match or it can be said that the team has never been defeated, but when meeting an ordinary team of course most people will be more choose the most favored team.
It's really risky betting on the underdog even though the rewards are very enormous should you win eventually but there is a 10% chance of winning and I am going to admit that the isn't really a great chance when the odd are stacked up against you.
