Ever slow up w/AA against non-scary board, no reads, & a checkcaller?

On a related note, do I have to push this turn? I want his chips!

Edit: This is sad, but I didn't even notice that the top flopped rag paired the board on the river until after I posted this. Don't know how much that changes the river betting. Thoughts on that?
