In the first sentence, it seems to me that to know expresses that the speaker experienced the problem/difficulty. I saw this sentence in the book 1q84: In (2), however, the object of.
I know (about) this difficulty/problem. Alright, well, for example, like on saturdays, y’know, what i liked to do. Using your example, knowing my rights means that i know i have. 'know of' is used when you have personal.
Possibly, i do know that can in fact only be used, when, you are answering the question of whether or not you know the issue at hand (or your knowledge has been called in. Recently one of my friends told me that there is distinct difference between 'know of something' and 'know about something' expressions. Why would you have a problem with this? Also explain the difference between the two, thanks.
What is the correct usage of phrase you don't know what you don't know?
