How often do you bluff the river after opp checks behind on turn HU?

Depends a lot on their went to showdown stat...having a fold to river bet stat is nice also.

More important than stats it depends what you have seen them call the river with before and what kind of hands you have been showing down and how much you have been folding to turn raises and stuff like that. Basically how likely it may seem them that you are FOS.

I think this move works best with a tight image--something I only have when I am totally card dead. Its brother the check the flop lead the turn move works well when card dead with nothing also--at least against those really passive opponents.
