Pre-flop note: The first time the hand came around to me it was a no-brainer to call the BB in position with a pair. Although I don't really like calling raises with a pair of 3s, when it came back to me after the raise I was getting a good price, closing the action, and had position.

** Dealing Flop ** : [ 2c, 3h, 9d ]
upstegrlspr checks.
pauillac checks.
arubio3 bets (6)
HERO calls (6)
upstegrlspr calls (6)
pauillac calls (6)

FLOP Note: I expected the pre-flop raiser to raise this weak bet and I could come over the top. Plan didn't work out with his call.

** Dealing Turn ** : [ 8s ]
upstegrlspr checks.
pauillac checks.
arubio3 bets (20)
HERO raises (100) to 100
upstegrlspr raises (200) to 200
pauillac folds.
arubio3 folds.
HERO ???

Turn note: This was a tough decision for me. Against a range of hands of AA-KK, 99-88 I'm a 2-1 favorite. Take away KK and I'm about even money. Throw in the possibility of a bluff and it seems like I've got odds to play this out but I'm a little lost.

What's your game plan from this point on, and comments on previous streets?
