No reads on the player as this was the 10th hand of so. No pokertracker stats on SB either. I was going to ask whether I should have folded on the turn but I guess the better question is whether I should have folded after the raise on the flop. Could have had a set and was in deep crap. I put him on an ace as well. Didn't think I could just call him down as I would have been all-in eventually.
