I like stacking off QQ+ as an overpair, or against some LAG players, TT is a solid overpair.

More than anything I think you need to work at getting some reads. Most of these posts are either fine or terrible depending on the type of villain you are up against.

If you don't have stats, watch the table when you aren't in the pot and make notes everytime you see some out of the usual play, like raising too often PF, calling down 3 streets with middle pair, or calling big bets PF with weak hands OOP.
