Hi all,
I am a beginner in PLO and just started the From The Ground Up PLO course. I find it quite difficult to learn the opening ranges properly as Emty just explains the ranges’ concepts and there is no definite way to self check if certain holdings should be opened. Any suggestion on this, without paying for another tool?

In addition, can u help re these specific hands from a recent session, should I have opened them?

Thanks!
