Check or Bet this river

I don't think you will get called often at all, but the times you are called, you will often see a worse ace.

His calling range is very narrow, but his range that beats you is narrower.

He can have AT,A9,A6 pretty easily, sometimes AJ and rarely AQ. You lose to A7 and 67. I think he plays most other holdings differently or folds to the river bet.
