[Eratosthenes]

33 hand: calling the minraise is fine unless you think someone behind you is likely to make a big raise, in which case you need to think about who the raiser might be, his stack size, the likelihood that he will pay off if you hit a set, etc. After the button repops it, you are getting enough implied odds to call, closing the action.

A9 hand: Your idea to isolate the limper is a good one. The problem is that you are playing so low that opponents will call with hands they like regardless of your raise size. With that flop you need to put out a pot sized bet to protect your likely best, but vulnerable TPTK hand.

in general: Your post shows that you have an understanding of NL concepts. I suspect that you are playing so low that you are not really learning anything. Maybe you should consider moving up.
