On the other hand, it's probably not so healthy to think about match fixing as a gambler that much because there's very little you can do to actually have recourse against it as a mere player, as match fixing is organized at a very high level.
If you have that kind of mindset better stay away from betting on those you think are fixed or rigged matches. As a sports bettor for a long and if you are a regular bettor of that match, I think you should somehow know or have an idea how to play well in that match regardless if there's a suspected fixed match or not. You can also take that as an advantage instead of a disadvantage.
In my own personal experience as a sports bettor, I only bet on popular league as even there's a chance of game fixing here, the organizers won't ruined their reputation for that as it's hard to earned people's trust and they are considered these leagues as business and they will protect it from any form of negative impression.
