I ever buy a fixed match like this 1/2 or 2/1. I have only ever won one of the three purchases.
usually the team that is not well known, in fact I really do not know each team. such as leagues from caste to 2 or 3.
With such high odds i do not care which league it is, as long as i can bet on it.
You mentioned that you have won one bet on such match, did you buy it from
