Flopped 2 pair vs calling station (pro edition), what's the best play?

[choccypie]

In the big blind with 96o, unraised to me so checked to see the flop.

Flopped two pair, not bad I thought. SB comes out firing at less than 1/5 of the pot, but I raise to protect two pair from possible straight draw. Turn brings a card I didn't want to see...should I have raised more on the flop or called after him? Or folded?

Read on SB - passive calling station and almost always limps in an unraised pot.
