25nl Zoom: flop 2nd and 3rd 5-way - line and sizing okay?

Villain looks nitty over small sample of 15 hands. CO looks like a standard tag over 60 hands.

Flop lead and sizing good? Same for turn and river (plan is to b/f both turn and river)? I think I go too big here on the river, but betting seems mandatory to try and get crying calls from AJ/AQ and maybe AK. He has some nut flushes in his range of course and possibly AT but overall we should be good the majority of the time. I doubt this guy bluffs busted diamond draws if we check river too.

I prob c/r this flop, I would imagine an UTG opener cbets this flop a lot.

As played, I'm b/f turn but I'm betting bigger, prob ~$8

As played, I'm also b/f river. Sizing is good in relation to how you played the rest of your hand and you can still fold I think if you get jammed on.

I think that you played this hand very well. I think that it's good that you decide to lead this hand. Maybe it would be better if you bet much more on the turn like $7-8, but however I think that it wouldn't change anything to the rest of the hand.
