Hero ?

Ok every draw just came in. What is the best play here? First orbit so no reads yet. check/fold is obviously not an option, check/call not really great since he can play perfectly against me and I dont think he will bet a worse hand ever and i lose value against worse ones. I know I wont be able to Bet/fold in this spot. And Bet/call also sucks because i payoff so many times when behind.
What do you think?

Final pot: 11BB
