I'm mostly interested in evaluating my flop play here, but I'll say something about the turn at the end.

Preflop, 3betting was certainly an option. Double suited I would have. I led the flop not because I had a range advantage but only because I think he checks back often and my hand suffers on many (perhaps most) turns.

I did not 3bet on the flop because I felt it likely that he would just call and I would be in a difficult spot on so many turns. I did not think I could get quite enough of my stack in to 3bet the flop. Maybe CR on the flop was better than leading.

The turn is obviously debatable. My fold was born of a conviction that the board pairing would worry most straight and flush draws (and even the straight if he happened to share it with me). His large bet did not indicate that he was at all worried.

I did not think I could call turn and fold river, so I folded on the turn. I should say that on this site, and at this stake, players are not bluffing much at all.
