He could easily be double barreling with 99-QQ, and hoping you don't have the K. I guess they could do that with KQ, although not likely they would fire a bet on the turn in my opinion. However, he would also be doing that with 55 or 77...

This hand would be so much easier to play if you were in position. ...(For the record, I'm not suggesting folding AK 3-handed because you will have to be first to act), but if they have 99-QQ, I feel like they wouldn't lead out into you twice in a row if you were in position.
