Betting into 3 people with a pair of 2's on the turn - 15-30 hand

[lil']

I thought a turn bet was warranted. This is on Stars, not Party. I am having trouble with the hand converter for Pokerstars hands, so I gotta type it.

15-30 - 6 handed

I have 2 [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/club.gif[/img] and get a free play from the BB. There is one late poster and 2 players limp. The SB completes and I check. 5 to the flop for 5 SB's or so.

Checked to bad EP player who bets. Poster calls, late limper folds, SB calls and I check raise the 3 remaining players, who all call.

Interesting. I feel I will be called by at least 2 of these guys, maybe all three, so I bet and am called in three places.

Is this turn worth betting?
