First off, how would you play the hand if 10[img]/images/graemlins/heart.gif[/img] came on the turn? Would you be scared of the flush? If you are, you should fold right here.

Anyway, to get our straight on the river we have a 15,63% chance along with the 4,07% of hitting a runner runner flush. Current pot is 8 and will be 10sb if you call. Let's say SB folds here. Another bet to call on the turn if you don't hit your straight but hit another club comes. Let's see:

In case a club comes you call 1,5BB and fold the river unimproved to win a 7bb pot by the turn. Since you will only make your flush/straight by the river 1 in 4 times (that is if a second club comes on the turn) and you will get the odds of 4,66-1 I like calling here. And to call the flop, the odds just don't quite match up to it but with implied odds and all, I call too.

Call the flop, fold turn UI.
