Stars $162: Couple of marginal spots

[bluesbassman]

Here are a couple of typical spots in which I have trouble, because of my awkward stack sizes and marginal hands. Not sure whether I should play these pots at all, and if so, what is my plan.

I was recently moved to each of these tables, so no reads on the villains. For the hands that I did see, everyone seemed to be playing basic TAG.
