AI problems with Create Black Hole?

Easy said hard done.
My uncloaked create black hole ships never reach their targets, almost every enemy ship comes after it (it seems that the the AIs knows its abilities and goals).
They are not escorted and easy prey, even a DN full of armor, shields and max movement points.
