AQ is probably in his 3-bet range. I think we're chopping alot with AK though after seeing his re-raise on the turn, and of course behind AA or TT.

Now that I look at the raise again, it looks like I'm either protecting my hand from a semi-bluff (like if he has KxKs or KQ) or hoping to get AQ to come along, with AK of course chopping (However I wasn't thinking when I played the hand, I pretty much bet because I was stuck and didn't want to bitch out of another pot lol).

Because I checked the ace high flop in position, he may weigh my range more towards pairs KK and below since with the flush draw he'd probably expect me to bet my top pair. If this is how he's thinking, wouldn't it be fine to stack on the turn since it's likely he'll bring along hands as weak as AQ?

The only reasonable hands I could put in his range that are ahead would be AA, TT, and maybe KsQs - not sure if he's 3-betting this oop though.

Once again, this guy is 14/11 with 3-bet of 8%. He's not your typical microstakes player that everyone seems to refer to. He's definately smarter about the game than your 'typical microstakes player'.
