UTG-1 numbers according to Pokertracker is 18.19/9%/1.50 TAG. Like it mattered because I didn't use these numbers in my decision making.

Well I flopped two pairs which is mostly what I want but the flop is very scary for me. I felt that I needed to get my money in before the person hit their straight on the turn or river. But I guess when person raises then I am stuck at trying to figure out this aggression stuff again.

I know the call of the UTG-1 re-reraise was stupid so I won't ask about that. So I guess my questions are how should handled the raised from UTG-1? Should I just call the raise and fold at another scary card? Should I have folded and if so what signs makes it obvious that I should have folded?
