My reads were BB has nut low and CO has either a worse flush or two pair/trips drawing to a FH or possibly another nut low. Anyone wait until the river? I figure if they're both on nut low neither is folding the turn but one may fold the river if they get counterfeited. If CO is on two pair he's probably not calling a river bet if he doesn't get there but he'll most likely draw since the pot will be so huge.
