readless, that turn bet scares me on such a dry flop, smells like a flopped set, or a floating 77 that got their on the turn.
I think QQ/KK re raises pre?
AJ is poss i guess, but not sure he raises the turn, ditto KJ, again i dont see him raising turn.

This is air or a monster in my opinion.

If villain is a thinking player, then the raise could be air, as he knows on such a dry flop and turn u are unlikely to be able to take much heat so deep.
However, i think more likely is that he has a monster here.
