I agree with Alex I think pre-flop is actually ok, depends how comfortable you are just calling, me personally I'd prolly just call cos the big big squeezes aren;t reallly my stlye, speshly OOP but I think it's actually prolly a decent spot as long as you dont have really sticcky players in the pot cos then you're prolly going 5way to the flop and thats not really what we want!
You've picked one of the best hands as well, although saying you never get called by something dominated is defo wrong.
As played once you've really sort of made your bed pre-flop and are now somewhat committed to repping aces the whole way and trying to force him off pocket pairs (which I think make up a large chunk of his range) obviously the more middle-cardy the board gets then the more likely i'd be to abandon ship, I think this board though is just about the borderline of what I'd keep bombing at..
One thing you abso CANNOT do in this hand is use your hand as a bluff-catcher OTT, you should expect this turn to go chk/chk a LOT as his range is basically all bluff-catchers and aside from sets or funky two/pairs he's never got anything to VB, and a pair dominated range will have no reason to bluff, you should bet the turn again here, and set up to jam the river imo. You have a 6 as well, so you block some 66 combo's and you can expect to win on a K or a 6.
Once you chk turn river is a slam dunk chk/fold, he has hardly any air that he makkes it to the river with, if i had a penny for everytime id though "huh, whats this guy trying to rep" and called off when he's not trying to rep anything, he just has a good hand and is betting it. Maybe you folded and got show

but even then it's still 100% the right fold.
If you gonna 3bet this pf you gotta be prepared to continue the agression post-flop, it's the biggest leak of pretty much everyone to be very aggressive pre-flop/on the flop, when peoples continuing ranges are much wider, and then much more passive on turns/rivers, where peoples continuing ranges are much narrower and your range SHOULD be stronger.
