99 in sb, flop an overpair

[fisherman112]

pokerstars 2/4, utg raises, 2 callers, i call with 99 in sb, bb folds

flop:8 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/heart.gif[/img]
i check, utg bets, call, call, i raise, all call

turn:T [img]/images/graemlins/club.gif[/img]
i bet, utg calls, call, fold

river:6 [img]/images/graemlins/diamond.gif[/img]
i check, both check

thoughts? i felt i played the hand for maximum value against overcards or A8 and minimum loss against an overpair (toss on the flop to a 3 bet)
