A simple question

[Billy LTL]

The game (full - 50-100) was as tight as I'd ever seen it, and less aggressive than usual. I was playing tight because my hands had been telling me to fold ever since sitting down two hours earlier. I was getting blinded to death, down almost five big bets on the blinds alone.

UTG I catch 66. What do I do? Given the nature of this particular game and my own image at the moment I thought the big blind, who normally enjoys defending, would fold much of the time holding less than stellar cards. But countering my present image six of the players at the table were regulars and knew I was not a stranger to limp-reraising (not that I intended to limp-reraise here but they didn't know this of course.)

So what should I do with out of position 66 in such a game? Limp, raise or fold?

If I limp, how many raises should I call if it comes to that? If I open-raise, how many reraise should I call?
