I truly appreciate the feedback. My thinking preflop was that I had three limpers already, had A2, and was ds. After the BB raise, I didn't cap it, though some people think I did. I figured I was up against another A2.
Four see the flop, I have top pair, second nut flush draw, nut low draw, and backdoor flush draw. The cap here might have been too much, since I had a naked A2.
The turn obviously killed my low, but gave me two pair. I raised hoping to get larking13 out of the pot after his call. After he cold called two big bets after the big blind raised, I knew he wasn't getting out and didn't cap.
The river was death, but I felt I had to call with that big of a pot.
