So I recently got essential here, and I've been watching a lot of pros go over hand history. I love watching people go over hand histories because it kind of shows you how you should be thinking about decisions. Anyway, I'll hear them talk a lot about ranges and what people could possibly have? How do you even start to figure this out, especially in the micros?

It seems like this is a huge part of people's though process, but I can't seem to even grasp how to come up with this. I've read some poker books, but having ADHD, it's very hard to retain what I read. Are there any videos on here that cover this, or can anyone give me a short and sweet version, or even point me in the direction of learning this? Because it seems pretty important when making decisions.
