A9o out of position is a bad hand, just dump it. And especially don't call a raise out of position with it
^^^. However... you have played it so: no, i wouldnt be re-raising on any street. The turn bet is small enough to call based on your feeling towards villians range and just checking it out on the river is fine. You managed to get a cheap showdown. but i wouldnt make a habit of playing that hand OOP like that.

hand 1: i think thats fine.
