[Closed] NL2 - T9s - BU - passive caller SB

I'm interested to hear others opinions about this hand. I kept betting because villain kept calling. When he didn't re-raise I guessed that he had a single diamond. Had he re-raised at any time I would have folded. My equity pre and post flop was poor but actually improves to 50/50 on the river.
