a few things that makes it likely I was beat are:
this player was one of the more solid players at the table. however, she had only showndown 2 hands in the last several rounds. they were both AA. I had folded to several allin re-raises earlier, so that info makes it more likely it was a move. if it has any bearing on the hand, she claimed KQ as her hand. oddly enough, I'm never inclined to believe players who tell me their hands.
all in all, its pretty likely I was beat, and my hand was only second pair anyway.
