Line check with 99 overpair. I think I'm up against TT : (

I like the flop raise only if you have some history with this guy or if he has reason to believe you make a lot of plays at ragged flops in position. I think calling preflop is fine as well, but I'm 3 betting vs a guy with these stats a lot in this spot. As for the river, calling is the worst option IMO, and I see no reason to think he has exactly TT, when he plays JJ-AA the same way. The only way to win this hand is to bluff shove the river, which can be good vs some, but if he doesn't like to fold I'd just muckem.
