Villain could have A8, A7, K8, K7, maybe T8 or J8s. He figures you could have A9 and may want to avoid getting c/r'd on the turn. His river raise makes me put him on an 8.

If you want to protect against a possible steal from a weaker Ace or K-something, I could see check/call. Betting and getting raised here sux. I don't think your good often enough to call although you might be good occassionally. I'd rather not put myself in that position.
