Fuper vs GB2005

[Bond18]

Two hands here:

GB2005 knows i'm a thinking player. He's capable of betting a scare card like that but i'm not sure what his flop calling range is here. I feel like if he had SD value he's normally checking back unless its a strong J hey may sometimes bet.

This one is after the first.
Two main questions:
Is my 3 bet size pre appropriate?
Is this flop a totally hopeless bet?
