nl 25, suited gapper facing turn decision

[Craggoo]

These are the sort of interesting spots i get into playing really aggressive. Based on his preflop range, i put him on JJ-AKs. The half pot bet on the flop and turn really screams out 2 hands to me for some reason; AxQd and JxJd which I felt i could move him off of them. Generally, people either bet close to a pot sized bet or hardly at all with the nuts which led me to believe he either had no diamond or had one that he wanted to get to a cheap showdown with. Any thoughts/opinions on how i played the hand?
