A/7 Flop TPTK what to do?

[Delzek15]

He's raised twice in this same situation so he could have anything IMO. Anyways... Is this standard here? Would anyone fold?

What did he have those two times?

Anyway, I have seen people play AK/AQ this way, but without a read that he's over-aggro, at this level opponents are usually quite straightforward, he probably has an overpair.

Is folding the turn UI weak-tight?
