Final Pot: t1765

First off I see so many people min raise with all kinds of hands so this doesn't tell me much, i see many do this w/ draw type hands even this guy has min raised and folded post flop.

The only thing I think I could have done here was bet out and fold to a reraise, but that leaves me pretty short stacked but alive (and BB soon to be 100). but I was also woried that he may play back w/some hands I could beat, A4s, med pair, QJ, given his stack and he seemed a bit loose. I felt the check raise would get me more money when I was ahead. Given the stack sizes if he bets out with not much he may call based on the odds. So do you play it safe here and try to get away alive if beat or go for a bigger score if ahead, or any better ways to play this? Does anyone raise pre-flop? I felt I did not have enough chips.
