Overpair on a board of one suit

[Blunderfull1]

Earlier I apparently made the CO fold Kings after I limp reraised, then he folded to my flop bet. He kept wanting to know what I had so I felt he might have been a little steamed. I just wanted to know how some other people wouldve played this hand. I considered raising the flop, but wanted to be able to fold if a diamond came on the turn.

You have to reraise that flop to find out where you stand. He would reraise with an overpair, the A or K of diamonds or a combo straight/flush draw. If he calls your reraise, he's still waiting for that last diamond to hit. By calling his raise, you have no idea where you stand.
