Premeditated bluff. A good one or just a reckless gambool?

I think that this bluff is almost completely worthless. Looking at the line here, you've called the first raise you've seen at the table by a known aggressive player post flop out of position with a really marginal hand. I think this is a fairly easy pf fold. You check-raise a diamond flop with a gutshot and a low diamond draw. Your villain calls. At this point, I would be hard pressed to put the villian on anything but nut diamonds or a set. Turn is an offsuit king, which gives you a couple more straight outs. My major problem is that if the villian is holding nut diamonds, many of his probable raising hands with that holding will include high straight features. He might have picked up a second pair or duplicated some of your straight outs. Worst case scenario, you're betting into top set with some redraws. I think I release here.
