One hand from last night

Here's one hand from last night where I felt like I made a very advanced play that paid off. Although last night was generally frustrating and I made quite a few stinkers, here's one where I really felt on top of my game:

I open-raise from MP1 with Kh Qh up to $3.50, it's folded to the BB who repops the minimum to $6. Relative stacks are $92 total, and I have position with a decent giant killer so I call.

Flop comes 7h 9c 8c, not a great flop, I'm prepared to fold, but the BB checks. Strange move given his preflop min-repop, meaning he either has a monster (AA would qualify) or he's getting cold feet with a hand like AK. Either way I'm not convinced I can push him off anything, so I check back.

Turn is the 4h, a good card obviously. BB checks again. I think that means he probably has AK, but I also recognize my opponent as being somewhat overcreative and suspicious. After checking the flop I have a hard time betting here, as he is likely to suspect me to have nothing here and is quite capable of coming over the top with nothing. With the heart draw I find it more prudent to play cautious, so I check back.

River is the Ah, for a board of 7h 9c 8c 4h Ah. I'm holding the stone cold nuts and suddenly my opponent fires out a bet of $8.

Obviously with the nuts I have to raise. But how much? The pot is $20 now, and my opponent has $78 behind. I take my time to think it over.

Conventional wisdom would be to give a small raise, one I think he has a high percentage of calling. Standard practice with the nuts on the river. But this situation is special, because I'm 99% sure he has some variety of AK here, and given that I checked behind twice, including once on a board that should have scared the absolute crap out of any made hand, there's no way he makes me for a set, straight, or goofy two pair. In fact he's going to have a bear of a time putting me on anything but AK as well.

So I push. A $70 raise into a $27 pot, highly uncharacteristic for me, but a play that looks for all the world like I have AK, I'm putting him on AK, and I'm figuring worst-case scenario is a chopped pot while maximizing his fold equity. He knows that I know he can't possibly have better than AK here, so he knows that my own AK isn't going to be scared. Which makes this, for him, a much more enticing call than TPTK ordinarily is in those situations where someone overbets you.

It's very hard for him to put me on the flush here since it was the Ah that rivered, and it's rare for someone to get involved in a 3bet pot with something other than a pocket pair or a hand with an ace.

My opponent called and showed Ad Kd; I scooped the $180 pot with the nut flush.

Obviously my opponent wasn't the sharpest spoon in the drawer and made several mistakes, the first of which was the donkish min-reraise preflop. Min-reraising pre is a stupid move 100% of the time, I'm convinced, unless you're in some kind of weird funky aggro game where you can do it with a wide range and still have an edge over your opponent's hand. It tables your hand, revealing it as something very strong, but offers your opponent just ridiculous odds to call and play perfectly from then on out.

Obviously, after that flop, he should have thrown out a continuation bet, which IMO should be standard practice after you 3bet without a VERY enticing reason not to. Why give your drawing opponent 4 cards instead of 3? In any case, after he fails to bet the flop, betting the turn is problematic, and that puts him in a very strange spot after he pairs up on the river, which in turn allowed me to capitalize.
