Anyone think it could be a good spot to check-back on the turn ? If I'm villain with AA-KK, I'm checking this turn often to let smaller overpairs or random junk put more money in the pot.

I don't like giving AK a chance to catch for free. I'd probably bet half pot on the turn and take a free showdown. That money almost certainly is going in the pot before showdown, so I'd rather do it on the turn than the river.
