I figure that in these games it's likely I'll be called by TJ|QJ|KJ|AJ and slowplayed big pairs QQ|KK|AA.

JJ|99|33|22|J9 are the hands I fear, but I decided that there are quite a few more losing hand combinations out there that will call me; hell, a hand like A9|K9 might even call me, "smelling a bluff."

I'm hesitant to bet less since I don't want to make a tough decision on the river, and the pot seems nice enough for this weak two pair.

Any suggestions, criticisms, comments, advice? A better line?
