QQ facing aggression from tightie... cap, call, or fold?

[Grendel]

I've been sitting at the table a while, playing very tight and very aggressively. (I've been getting ass cards, and thus look something like 10%/6%/4.0 to someone with Poker Tracker.) I'm up a decent amount. I don't think many players notice, though, because I still get calls everywhere -- got called down by king-high two pots in a row.
