I am new here, I have been a casual poker player for about two years, and because of my personality am frustrated I don’t understand at a higher level. Can I get some help with what videos or info is on this site for these topics?

What my equity is against an opponents preceived range.

How to construct a profitable and balanced 3bet and 4bet range.

Bet sizing tips versus ranges.

What programs are apps will help me better understand the math and frequency questions.

Also what is a dice roll or randomizing?

Thank you so much for any help,

Whof.hearted
