I don't think calling pf is all that horrible, as long as hero knows how to play post-flop. But if he says he NEVER knows what to do, then yes, he should be folding. Also, at the low-buyins a minraise UTG will mean they have AA-QQ about 30% of the time, maybe more.

As for post flop, I think I check fold, the flop didn't hit me as favorably as I wanted to, I'm getting out.
