I feel like I played this hand poorly by not getting two streets. Villain is a reg that seems to be decent but I don't have much history with him. Based on the 1.5hrs or so I played with him I would say he is a winning reg but not a pro/crusher in this game. I perceive his defend vs 3bet pre-flop range to be mostly 1010-QQ, AK, AQs and occasionally wider hands like 99, AJs, KQs.

I decided to check turn to control the pot size as the flush just came in. On the river I went for a check call because I felt he was more weighted towards 1010-QQ and the K was a scare card for him. In retrospect I think bet-fold was the better line on the river as I don't perceive him to be raise bluffing river ever (very uncommon in small stakes). Also unlikely to raise river with worse value (namely AK). Thoughts?

Thanks for the feedback!
