Turn AA into a bluff?

[Andrysmor]

Villian is tag, not tricky, capable of laying down a strong but not nut hand and does not make thin river bets.

History: We have tangled a few times but have not gotten deep into a big pot together. Other times he has seen me play tight and show down big hands when big money goes in. I have made several tricky bluffs but none have been called.
