As played here I think you are fine to just call. You beat a decent few aces your opponent can have so happy days, sometimes they'll turn up with 2 pair but oh well, he didn't bet big did he (or she).

Given their sizing I think calling down here is totally fine. Don't like raising too much as if we are faced with a 3bet I'm not loving life.

Not folding the river for that size, calling because we don't have to be right that often to make it profitable + getting a note.

Without reads I'm assuming villain is passive. I would expect his flop donk to be a random Ax a lot of the time, but he does have all the strong hands too.

Turn is still a call.

River is nasty. It's easy to justify a call because of the stakes, but he's only legitimately value betting AQ AJ that we beat. There's a lot of aces up combos too, and we can't expect him to bet a hand like A8 for 3 streets everytime. 98 got there as well.

People will shout nit at me, but I'd make a fold even getting those odds.

To get away from this situation I still think it's worth considering raising the flop because if we get 3 bet we should be able to fold happily.I wouldn't expect him to go mad with AQ AJ once we raise.
