Do I have pot odds here?

[Lawrence Ng]

I'm in the big blind with 3 [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/club.gif[/img]

It's a 10-20 game.

Cutoff limps, button limps, sb calls and i check.

4 small bets in the pot.

Flop comes 2 [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/spade.gif[/img]

SB bets, I call (backdoor flush, open end straight draw), cutoff calls, button folds

Turn comes 3 [img]/images/graemlins/diamond.gif[/img] giving me a pair now with a straight draw.

SB bets again. Do I have odds to call for my straight, trips and/or two pair if it's good?

Thanks.
