5-5 blinds short handed (making a move post-flop)

[stankybank]

I'm the button w/ 56 spades and I raise to 25 or 30, foggy memory after a 1 day session. This was a live game and the bb in this hand was a very aggressive, young asian lady who is a 'thinking' player and isn't afraid to bluff. We were playing a full-ring game up until this point and her and I pretty much respect each other's play.

Anyhow, sb folds and she reraises to 100 more. Normally, I muck this hand really fast against any other player but she was doing this quite often and I know she doesn't have a hand each time. She's been up and down in this game big time and she's finally starting to make a comeback by resembling an "Ungar-like" presence at the table. I put her on almost anything at this point and since I'm going to act behind her I figure I can narrow her hands down post-flop. So I call. I have ~2500 or so and she has me covered. I figure I can get paid off big time if I hit.

flop is KxKr. The 'x' card was one of my runners for a straight and there was also 1 spade on board though I don't remember if it was the K or not. Sorry for lack of details.

Anyhow, she thinks for a sec or two and fires out 100. This to me feels like an "ace-high bet go away let me take the pot down bet." I think for 3-5 seconds or so and raise to 300 straight. I'm trying to represent a K w/ weak kicker or pp above the 'x' card just wanting to take the pot down right there.
