Pot 1075

Erik instabets 1200

What is my line here?

Half the deck are scarecards and I know he won´t hesitate to give me pressure on turn and river whether a scarecard comes on turn or not.

In cashgame and tourneys the stacksizes often aren´t deep enough that people bet out to the raiser in reraised pots without committing themselves so this was a new situation for me. I know or at least I think he´s really loose, what handrange can I put him on here?
