TURN: Looks OK. CO might have made a set of Eights on the turn. Especially since he is a bit of a maniac though, he might have been overplaying a heart flush or OESD. Maybe he had a combination of the two and he was semi-bluffing.

RIVER: I don't like this fold. If he was on a flush draw, hearts seem more likely than clubs. If he was on a straight draw he might have made it, but it's worth a call for one more bet in this large pot. He could have been bluff betting a missed draw since you checked. He might have a read on you that you fold the river too much.

Edit after reading thread: Your fold was good here, but if CO is a thinking player, since he saw you lay this down, he may be more likely to try to bluff you next time when he misses. Try to be aware of your table image to help you predict how they are likely to play against you.
