I like my line here but it is quite a weird hand, obviously it worked in this instance so I may be biased.
Not much info on villain, but his big stack and playing 2 hands from 9 so far suggest not too fishy.

Flop: I am happy calling or raising my gutshot+BDFD, I choose to raise here as I want some non-diamond bluff raises with equity. I am also raising good Jx, overpairs, sets, some diamond draws and some overcard hands with a diamond at some frequency.

Turn: I think I have a significant range and nut advantage, an overbet pressurises his Jx and folds many of his draws. We are deep and there are lots of megadraws out there that may still call. In hindsight a bigger overbet could be better? I can have KK and JJ which he shouldn't have. I will also overbet some diamond draws on the turn, particularly if they have additional equity.

River: I am not sure about my sizing here, I thought about overbetting, but my nut advantage is much lower as we can both have KJ and KK is 1 combo. My concern is that he can have KJ, 44 and 33 which likely raise or call any size. I have to bet something to fold out his missed diamond draws like QT, Ax, 56, T9 and I think my 80% sizing puts pressure on AJ and QJ. I am not following through with AXss or missed diamond draws.
