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?

AxQd and JxJd

if that's what you thought he had, why did you call the flop? Just to bluff all in on the turn if another diamond hit?

[bsball8806]

or if you didn't think he had that until the turn bet, what was the flop call for?

I answered both these questions in my original post I believe. Playing TAG is boring, uninteresting, and really not very profitable. I realized after my big session today that the reason I haven't been winning recently was because I was playing far too nitty; I literally never tried to steal a pot from anybody. At least half my profit today came from turn or river bluffs on potential bad cards for villain's hand.
