I bet once in a while on underdogs in football and one of the game surprised me because the odd was very big and I decided to just give it trial and to my greatest surprise,it brought a win for me. You know as humans,when something works for you,you will think that it was your instinct or a good strategy that you have discovered. After that day I started betting in underdogs but I lost. I later went back to my normal way of betting,sometimes I still try my luck on underdogs because if you manage to win,you will be having a good profit. If you are gambling for fun then it wouldn't be a problem to bet on underdogs just for fun.
You are very right, underdog are a great way to make some good profit if the gambler is lucky to win a bet on them, as the chances of them winning are always very low, that pushes the odds high which brings about good profit they find their way to win.
Last time I had an experience of betting on underdogs and winning was during 2022 world cup, I am no longer sure the particular team, but I think it should be Morocco and poland, many never expected Morocco to beat poland, I myself didn't believe it would happen, I just decided to try out my luck since several bets was already on poland wining, and the money wasn't as much so I was ready to lose it, so I took my chances on Morocco, and to my greatest surprise, then won.
Ideally, betting on the underdog with a first half match option. with the scenario, the team that is not in the seed score first. but this option, the risk is very vulnerable because the time is only in one first round. another alternative, we can choose the underdog team when the favorite team is not showing impressive performance. in fact, tend to play mediocre. I can take an example, during the Japan vs Germany match at the Qatar world cup.
If I'm not mistaken, the Japanese team has odds with @16.00. well, if we have analyzed before this match, Germany played its match not like a big team attached to their big name. Based on this anyway, we already have points for further consideration. on the other hand, Japan is not a superior team. but the fact is, they have an excellent game with spartan and tireless. this option, can be considered for betting on teams that are not superior. so, it's not easy to choose to bet on a team that is not at all superior even only has a very small probability of winning, there are also other matches such as Morocco vs Portugal.
The point is, however, that we don't necessarily choose the underdog team without calculations and involving research. that means, we shouldn't bet blindly without first investigating the potential of a team that is not superior. therefore, in football, we must involve extensive knowledge, skills and insights. plus, sharp instincts in a way involving experience. If I may say, it's not uncommon for me to win bets on Underdog teams. but once again I say, all of that always involves many factors and research.
