Posting blind: if you've played the hand correctly to this point, and if it's really a decision, then the answer is probably fold.

Having read your post: 0 for 2.

As to misplaying: why didn't you cap the flop? This Villan is overplaying Jx WAY more than he's got a set, and there's no two-pair for him to have made. Most likely he's on a diamond draw plus second pair.

As to this being a decision: well, yes, you have to pick an action. This is a pretty easy raise, tho. Try to get the blind to leave, and pump your equity against his most likely holdings. If he 3pops, call down.
