AQo HU -- too tricky?

[private joker]

I sort of played this hand on auto-glide instinct (felt like a smooth-call from the BB instead of a 3-bet due to being out of position, felt like a fun time to check-raise, etc.), but after I bet the turn I got worried that I was spewing. I got lucky, but what should my plan be if this guy calls the turn? Check-fold the river unimproved? Bet and fold to a raise? This was fun and terrifying and satisfying and confusing all at once.

No reads on Villain except he has the biggest stack at the table twice over.

It's good. It's a nice line if you don't overuse it.

If he calls the turn bet: check-fold the river if you don't improve.
