3bet AQo OTB, 2/4nl

[tagtastic]

I have no meaningful stats on the villain during this hand, I've only been at the table just over one orbit, in that time he hasn't done anything weird, raised twice pf and took it down both times I think.

Comments welcome on all streets. I have obviously under represented my hand here, do I have to call this because of that, or can I throw this one away? I find it fairly hard to believe he's value betting a worse ace (that he'd call pf with) or 2nd pair here.

Also, what changes if he's fairly nitty (14/11, and assuming I still choose to 3bet pf)?
