It looks to me from this action that the villain, has either 99,QQ, or ATs. On the river you are a 6-5 favorite to have the best hand so I would call. You induced a bluff by checking the turn so I think you must call the river. The mistake you made in this hand was not betting the turn, and thus you lost control of this hand. Betting that turn card should be easy since you can easily fold to a checkraise against most players, and you still may have the best hand.
