Some confusing hands

[pearljam]

All of these are 30+3's, by the way for anybody who cares im 5% ROI over my first 300 which is disapointing, I was hoping for 10%, but im confident that I played well and deserved 10%.

It really burns me when I pay this stupid bet off, it seems like they havea higher pair when they make this stupid bet so often that I should just be folding this, of course if he open pushes I automatically call, is there any way I fold this without reads in a $33?

Final Pot: t1485

Should I have checked the flop? If so what is my plan from there? Should I bet and then fold to this raise? It seemed too likely for him to be "protecting" his 2 as most $33'ers would slowplay an 8 here, at least that was my logic during the hand.

Standard? or does the risk of him callign with a big pair or something that coinflips me too big here, especially without a dominant chip lead?

Any feedback would be great.
