River Js UTG bets MP raises! I have the Ace Should I call even if I know he has the Straight Flush. the pot odds are their but I know he has it.

I know a lot of you will say why didn't you raise. I felt anyone with the 8s Js or Qs was staying no matter what at least that was my read. Comments thanks
