This is probably more applicable in live poker. But I think its still valuable online. 

I’d like a video of different types of players.
For instance you have a calling station who never folds. Things to do against
them, never bluff just value. Tag player: good spots to bluff them or when to fold. How to
play against trained players.

Also how to identify such players, what labels you guys give
them and then how you would play them. 
Hope this makes sense.
