At this level it is very hard to say what opp has, he could have 68o/s, A9, 99, 77, 55, Ax, 5x, 7x, 9x, or pretty much any two random cards depending..

Without a read here I don't think you can do much but fold. I usually try to avoid raising the first hand at the table unless I get QQ-AA, I know it sucks but they're nto going to give you any respect on the first hand, so just show down a good hand first.
