"Protecting" my hand?

[manik]

UTG+1 is fishy, 51 vpip, .6 pfr ~200 hands
MP3 just sat down.

Final Pot: 20.50 BB

After looking at this hand again, I'm wondering if I should have just called the flop, then raised the turn when no diamond falls. (I assume that BB would bet out again, otherwise I would just bet.) but I'm not sure.

And then my raise on the river.. does that seem like MP3 just made a backdoor flush or straight? Or am I just seeing ghosts?

Thx.
