NL10 How do I respond to this turn raise?

[Roger Mainfield]

This was the hand after I got 30% of my stack in pre with AA agaisn't A9 and flop is 99x so I might be tilting a bit. Villian was unknown at the time, I had just sat down. What do you guys like after he does the tiny raise on turn? I was on autopilot or something for the flop bet, would usually do about .85 here.

baluga whale theorem states that you should fold here.

i think that folding is probably best. with the K[img]/images/graemlins/diamond.gif[/img] i probably shove, though its close.
