PRE-FLOP:
I thought it's ok to call here. Thanks to w34z3l I know thats it just to loose to defend QJo vs EP OR 3x.

FLOP:
I decided to x/c for value since on this board he might bet all the hands he missed.

TURN:
Here I went into bluff catching mode.

RIVER:
Decided to x/c because if I raise - worse hands might fold, and better hands would call or raise.

1) As played I think that flop is played ok, is it?

2) Should we fold when Ace comes up?

3) Should we lead river, or c/r ? I think calling here is fine ?

Thank you for your great job doing evaluation!
