Good spot to raise allin?

[Orsman]

Villain is unknown and I'm new to the table. Have seen him limp once before. I isolated and got 3bet from blinds and folded.

He ista minraised me on flop. His turn bet is kinda weakish and I think this is a decent spot to shove him in... or maybe just spewy against unknown
