What is the best way of creating mixed ranges? Is one expected to go on on to poker stove and make our own or are their defaults? Are their any recommended videos or series on the practicalities on using such tools for this purpose?

How do I decide whether to call or 3-bet my cards that are marked as mixed? Do I set like a randomiser for 50/50?

At what kind of sample size should we be looking to change to a polar or linear strategy?
