TT OOP need help

[DawnToDusk]

What is this guy calling with? Obviously we have no reads and don't know what any of his proclivities are but on the river I feel like you will be shown an ace. It would be pretty sick if the guy called the whole way with a dry ace and it would definitely cause me to get up out of my seat and take a quick walk around my house.

I suppose he could have something like JJ/QQ/KK and wanted to play them sneaky but come on the turn he can't raise for in fear that you have a nine. But I feel like this is such a small percentage of his hand range because we would of expected a raise from these hands either PF or on the flop.

I don't think he has a nine either as he doesn't raise anywhere in the hand and you would think that he would get his money in on the turn or the rest of yours on the river.

Could he be hanging around with something like 55-88 and just not believing you and being stubborn? My inclination tells me that I feel like we are going to see a sick ace on the river just from how passively our vill played the hand. I feel like any other hands that he could possibly have would put in a raise somewhere during the hand.
