Very good and simple post, that cbet part is pretty much what i say to do when im teaching new players.

4. I think this needs to have a special exception "Fold to a fourbet shove unless u have KK+ at 200nl and 100nl versus's nits." I know this sounds ridiculously outlandish, as I can't even think to fold those hands pre in the games im playing in right now, but im almost positive this is correct with all the nits i played with at 200nl.

Calling oop isnt the answer.
