hand history is being dumb (like my play) so heres the situation.

blinds 25-50 i just won a pot off of MP and am at 2500 stack with 5s3s in the SB. UTG fish limps, MP goes all in for 180, and its folded over to me. I figured hes moving any two here and with the blinds and the limp i was getting a good price at a 500 pot, so i raised it to 600, then UTG limper pushes over the top for 3k more and i fold.

what do you guys think?
