QQ facing aggression on flop and AI on turn

[kerplunkNL]

No reads on villain, just sat down.
When he betted into me, I wanted to know what the guy had, so I reraised. He called, but I wasn't sure so I wanted to check behind on the turn (good?). But then he pushed. Instafold on this kind of board?
