How bad is my opponent's line vs me

I thought his line would be donkish but after second glance I don't hate his river raise that much. Hero in this hand has donkish stats at 26/12 where I have a predictably narrow range on this river.

Your turn/river bet sizing makes me think AA is very frequently the best hand here.

Meh, I'm almost never flatting Aces pre-flop because they help balance out all the crap I'm raising on the button.

Flatting the button to draw a second barrel is reasonable enough, but I'm raising the turn. $175 works.

I just don't like giving out a full 7 card hand against my Aces before showing any aggression.

playing AA and other big hands like this may not be great for balancing a lot of styles, which sometimes isnt important, but in isolation this hand is good.

the question is where to raise, not if a raise is good since its good on all streets.
