'If you think you do, then play like you do.'

This is exactly right - the ONLY way to effectively play a trash hand is to just play it like the hand it immitates - i.e. KQ is AK, if you hit top pair you're golden. For this reason it's a terrible hand to call a raise with, and it's a terrible hand to open with outside of LP. If someone limped in front, then you raise from the button and they call you, they probably don't have KQ dominated. If you get re raised it's time to let it go.
