PLO25 AA86ss postflop calldown versus aggro?

With your reads and passive line i'd call this river.

Like preflop. Flop we block A2, 26 and 64. Question is what you he would do with like pair on FD considering the runout. The runout favors you definately unless he didn't flop it. But overall if you consider calling down this is probably as good of a runout as you can get. Turn is definately the key point. I agree with Nunki that when you call turn you probably gotta call river too since you beat 53 now and everything else busts.

Any reads on his betsizing? To me it looks like he have It. Could he play KKhh,QQhh w som blockers same way?
But maybe it' s good spot if you call turn to hero river. Not sure. Surely he could have som bluffs just hard to
see it to often at this stakes.

He was betting on big side in general. Turn is kind of key point because if I call there with hand that has like 4 good cards then I have to be willing to hero lot of rivers as this guy didnt usually slowdown.
