value c/r river scare card?

[ofishstix]

I was happy with the way i played this hand until my friend who's very good at nl suggested that i c/r river b/c its obv that button doesn't have flush. Ive been thinking about it for a while and BB could have flush or set so I dunno if its worth trying?

Sorry for the poor writing, I've been up 26 hours.
