if I get this right..so you raise for information, and if you have an ok hand and they re raise you then you're probably beat ? but what if they just call and call. and then you don't want to raise and you check , and they make a big ass raise. you don't get an info ...

If they call and call, then you check and they bet, I would think that it means they are slow playing a hand or made a draw. It could also mean (if they are playing aggresively) that they sense weakness and are trying to bluff you, but I think the first two scenarios of made a draw or were slow playing are the more common.
