Junk top pair in the BB

[pstripling]

Party Poker 9 handed. Loose table. Hero is BB

1 fold, 2 calls, 2 folds, 2 calls, SB completes, (BB) Hero T [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img] checks

6 players (6 SB)
Flop T [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/heart.gif[/img]

SB bets, hero???

I don't like folding top pair here but there are just too many ways to lose this hand by the river. I strongly doubt a raise is going to win this hand right here, although it may limit the field a little as someone MIGHT fold something like K [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/heart.gif[/img] for 2 bets....but they just as easily may call. Any advice would be helpful.
