99 on the Button

[Chief911]

Background:

I had been position raising quite a bit, and the table was growing a bit testy. BB in this hand only had been here a few orbits, but had played back at me once.

Villian (BB) has me well covered with about 30k. I have 20k. Blinds are 400/800.

Folded to me on the button with black 9's. I think I made mistake #1 here. I limped from the button. I dont know why. I cannot explain it.

BB makes it 2400 to go, and I call. (Mistake #2?)

Flop is 553r. BB bets out 8k.
