Preflop: Hero is SB with 6[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/club.gif[/img].
UTG calls, <font color="#666666">1 fold</font>, CO calls, Button calls, Hero completes, BB checks.

Flop: (5 SB) 4[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(5 players)</font>
Hero checks, BB checks, <font color="#CC3333">UTG bets</font>, CO calls, Button folds, Hero folds, BB folds.

A good table, with everyone that limped has a 45+ vpip and a 15- PFR. Does anybody call the flop and if not how high of a club do you need to call?

I need the Q[img]/images/graemlins/club.gif[/img] to call there, maybe T[img]/images/graemlins/club.gif[/img]. It helps if you have any reads on CO because if he's aggressive, it's more likely that he's drawing to a club as well because he's more likely to raise pairs worth peeling.
