Is this fishy? (bubble $11)

[Isura]

I've been raising button quite a bit. SB is playing very tigh, bb is playing more loose but passive (not reraising at all). Do I just dump this PF? I thought postflop was pretty standard. On the flop I might be ahead, but I don't think its worth risking too many chips where he won't fold better and may take me off my hand. Turn I pick up outs, but I still can't get a better hand to fold, and c/r would make me sick. But maybe turn calls for a small protection bet? River I'm probably good, so I check. I'm mainly interested in hearing thoughts about the merits or pitfalls of getting involved with hands like this in this spot.
