Flopping the stone-cold nuts. Did i take max value?

So i have KK on the BB. sitting around 2$ (100BB) maybe a little more cant remember. guy opens from middle position for 6c and i 3bet to 20c. he calls.

flop is K2K (2 diamonds)

I check and he bets 2/3 pot. i call.

turn is a 7 making another flush draw.

i bet small... 30c.. making it look like a scared blocker bet. a scared pair of JJ or TT.. even QQ or AA. and he raises to 90c. at this point he has 86c behind. and with the flush draws on board i basically thing that by shoving i get all his draw to pay me off (they are commited to call) and i think that if hes bluffing (which is most likely since i have both kings) hes probably going to shut down on the river with only a quarter pot bet behind. so i shove it. and he folds. was there any way to spike another bet on the river?

maybe checking? would he have shoved a bluff? or making another small "weak" donk bet? he could have paid it off with 88-QQ... not sure.. maybe he had Aces and he wasnt bluffing. but it really seemed like he was done with the hand in any case. (i thought about 88-AA without KK obv because he could have raised for information.. i know its stupid but its possible)

Shoving turn is the best option. You said it yourself, if he has a draw he will pay you off. If you get to the river and his draw misses you will miss out on that value.

This is a prime example of why it's hard to get value when you are out of position. Most of the questions you have would have been answered by having the information of him betting first.

I think people put others on a flush draw way too often. Having two suited cards and flopping/turning the flush draw is not as common as people think it is.

Shovinc turn is alright though. Not many other options we have, but I find that you played the hand quite interestingly.

On this type of board I'm probably c-betting though. We don't really rep anything other than KK, AK, and KQ, and I expect to get floated a lot on this type of board texture. Any PP and some A highs, and of course the flush draw. And I would check-raise turn, or maybe mess around and flat turn, then make a min-bet/small blocking bet OTR to induce some spazz.
