Even if villian is tightish post flop his range is pretty large. He would certinaly do this with KdQ, any AQ. Plus, he bet half pot. I call and if not diamond put out a value bet on the river.

Doesn't make sense. OP has Kd. Call turn and either check/call check/fold river if you don't improve. This could even be a straight that came in, there are plenty of draws. If you hit diamond, I still probably check.
