I feel my hand plays best when I c/c, as I don't think I get much action from hands that I beat. The problem is, AT/AJ are the only hands I would c/c with here. He doesn't know that, but I still don't want to get in the habit of playing transparently if/when I get to higher stakes.

Is narrowing my range to only two hands a problem if I'm aware what I'm doing to my range? In other words even if he knows I can only have AJ/AT here, I know he knows that?

I know this doesn't matter at NL$50, but still something I'd like to figure out.
