I will try to explain a bit to you, as you can see in the screenshot he shared, according to op, he was choosing games for this parley bet, having made a choice in all of the sports he was familiar with, he decided to add one game from sports he was no really familiar with (for example, it's like someone who doesn't watch table tennis games, but decided to bet on an ongoing table tennis match, it will be difficult to know the right team that will possibly win the game; and bet on them).
At the end, it was the game from the sports that op isn't familier with that ruined his parley ticket, every other bet won except that one, and this is why op is advicing us all to always and only stick to sports games we are familiar with when betting.
And when you check the picture again, even from the OP explanation you can see that game was the only game with a complicated option, even me didn't understand the option, i also had to check information about the option and you telling me I wrote this long with no meaning. That very rude of you.
And you say there were other high ranking members that read the op and commented from the same perspective as yours, please point me to their comments, forgive me but I saw none of those except yours, and it's the reason why I decide to correct you.
But any ways, I am not a trouble maker and neither do I have time to banter words with anybody including you, so, I will apologize for approaching you in a manner that made you think or assume was rude, I wasn't being rude to you, but sorry if you think I was.
