No. I just think a c/r is inherently wrong unless there is something seriously wrong with the opponent.

It folds out all the worser hands he might otherwise have called several streets on.
It makes him play cautiously all the worse hands he might otherwise raised us with.
It takes away his ability to "raise a donk" and bluff us with ATC.
It gives villain a free card if he is drawing.
It does nothing to disguise our marginal hands.

The only uses for a c/r I can see is multiway with a very good relative position on the pfr and on the river. Basically when psr gets really low, like a flop c/r when villain is a shortie or a turn c/r when the pot is bloated from OOP and villain will be getting like 4 to 1 to call.
