$0.50/$1 NL - A-A against big flop check-raise

[tekmo7]

Home game, 10-handed, VILLAIN is a very good, tricky player who knows my game pretty well and has the ability to make big bluffs. His range from MP is small suited connectors to middle one-gappers to suited Aces and up. Also, he has no physical tells that I have come across.

MY STACK: $175
VILLAIN: $220

Blinds $0.50/$1. Game is loose-aggressive.

I have a very tight-image at the table, so VILLAIN knows I have a big pair, so I don't think he would do this with a mid-pair like 10-10 or even J-J (both hands that VILLAIN could initially limp with pre-flop). But maybe he knows that I am a tight player with a big hand, so I would not believe that he would make a play like this without trips or better - hence a big bluff! I don't know...I am seriously considering a fold. Either he hit the board hard or has a draw...I think...lol.

What should I do?
