My first short handed table session... 1 hand needs advice

Hi all,

Please comment this play:

PokerStars Game Holdem No Limit ($0.05/$0.10)
Table Gondola II 6-max Seat #5 is the button
Seat 1: typical18 ($10 in chips)
Seat 2: VILAIN ($14.25 in chips)
Seat 3: HERO ($10.05 in chips)
Seat 4: KULakester ($18.95 in chips)
Seat 5: ennilein ($11.30 in chips)
Seat 6: custe ($21.20 in chips)
custe: posts small blind $0.05
typical18: posts big blind $0.10
*** HOLE CARDS ***
Dealt to HERO [9h 9s]
VILAIN: calls $0.10
HERO: raises $0.30 to $0.40
KULakester: folds
ennilein: folds
custe: folds
typical18: folds
VILAIN: calls $0.30
*** FLOP *** [2s 4d 5c]
VILAIN: checks
HERO: bets $0.80
VILAIN: raises $1.70 to $2.50
HERO: calls $1.70
*** TURN *** [2s 4d 5c] [8s]
VILAIN: bets $2.80
HERO: ???

A) Is the preflop raise ok, or better to limp and play for set?
B) Should I fold the raise on the flop (in retrospect this is a classical check/ raise... prolly straight or set.)?
C) He fires again, what to do...

Thanks for your advice!

what do you know of villian

Hmm, I would say he was loose, limping a lot but not really uberaggressive, his image of me was probably LAG (I was playing lots of hands, because I had a good run of cards, but I didn't went to a lot of showdowns.).

After a night of sleep I still think it's possible I had him beat (he took a stand with overcards or lower pair with A kicker or something, but chances are also that he had me beat.

Greetz,
