back to basics: one card flushes

standard LHE game, no one notably aggressive.

you have some paired hand with a club in it, like 9x9c. you raise preflop and the sb and bb call.

the flop is all clubs with a higher card than a 9, like Qc3c4c. you bet and get check raised by the sb. bb folds. you call.

turn is some card between T-K that isnt a club. sb bets.

call or fold?

if you fold, what is the lowest club you call the turn with?
