I don't think I could lay down here. Would he 3-bet an OESD OOP on the flop? Would he be likely to slowplay a set on the flop? If the 9 is not of the relevant flush suit, is he savvy enough to think you raised the turn having picked up a flush and straight draw with your T-9s or J-9s?

I think he has a hand you can beat often enough to make the call.
