preflop: fine.

flop: fine. board isn't dangerous though. Q66 2 tone board is far from dangerous if you ask me. I'd generally feel good holding a hand like AQ here.

turn: fine. You havn't put a whole lot into the pot and you don't have a hand. see if you can check this down with possibly the best hand. hope for a river K/A. if it doesn't hit, I check behind, maybe call a min-bet if I don't connect. If you do and he checks to you again, I think you can get in a pretty thin value bet.

river: fine. I don't think you are good enough here to call this bet.
