NL50 - Check-raise river bluff

[Kharlog]

The opponent is mostly unknown. Do you like this play at all? How do you determine whether to do this moves or not? I need to win this pot (7/(7 + 4.5) =) 61% of the time and my opponent need to win (1/(11.5/5 + 1) =) 30% of the time to have a correct call. So basically this is correct only against on a particular situations and against tight players only? What kind of hands would you call against that kind of move without reads?
