Adventures in NL - 99 hand

[nolanfan34]

Hey all,

I'm a newb to this part of the forum. Been trying my hand at low limit NL, instead of my traditional limit game. I'm finding myself in a lot of situations that I don't feel comfortable pushing my hand in. Ah, the safeness of the limit structure....

Anyway, here's a situation I've found myself in occasionally. What's the best line?

$.50/$1 blinds on PokerStars. Table has been loose PF, even to a raise.

Donkish player opens for $3 in EP. This raise doesn't mean much necessarily. Earlier he check-raised with top-pair with ATo, then called my all-in bet with my overpair.

I call with 99 in MP. One other caller, and the BB calls. First, is my call OK? I had $75 or so in my stack at the time, PF raiser has me covered.

Flop of 852 with two hearts. I have the 9 of hearts. BB checks, and the PF raiser bets $6.

What's my play here? Standard line is.....?
