short and simple question

I am on the BB with KQo.

UTG - an agressive player whose raising standards in early position are at least JJ and AQ - raises. Everyone folds and I am headsup.SB is 1/3 of a bet.

How far off am I in folding? Comments appreciated.

then you should always fold. but you also should be certain you know your opponents standards for raising and not what he just usually does.

Thank you very much for your response.

So it wouldn´t be right to fold if it was only what he usually did?. But what evidence of a players raisings standards can one possibly have other than one´s observations over a period of time.

And would it not be enough reason to fold, if he had those hands only 9 out of 10 times ?

He has the advantage position.

And in my case the advantage of experience probably too:)

Thanks again
