$10/20 guppy- AK in the big blind

[Easy E]

<font color="blue"> See my previous post titled "$10/20 HE- Low-limit guppy" for the precursor to this post. That post contains all of the background that I'm not reposting here. </font>

During the next circuit after my KK in the previous post, about an hour into the session, I have AKs in the big blind. UTG raises, all drop to me. I reraise, he reraises, I call. How many bets do I take it heads up against a UTG opener in this situation? How about in general?
K92 of clubs flop, I check-call with my TPTK but no draw. Turn is Jack off, I bet, he calls. River is 9d, I bet Should I have check-called here?, he calls with AcA.

Comments? I'll try to put some more out here tomorrow.
