The good ol' gambling temptation, huh? Happened to me as well during the recent World Cup. Can't stop them itchy fingers when those two teams had neck-to-neck chances, yet still lost
Well there is nothing to be ashamed of. Its completely natural to want to gamble sometimes. Especially during times when there is a huge global event going and everyone is gambling on who will win, who will lose and so on...
The amount of team analysis people do is insane. I do not have the patience nor the motivation to research stuff like that before I put in a bet. From my own subjective perspective, gambling is supposed to be fun, not a research chore.
Either way, it always feels like its impossible to tell who has a better chance than someone else.
