Does a divorce occur with the husband's words "Then it has happened" if he intended divorce and the wife understood it, or with his words "Consider it one divorce," or with his words "This is one, and you have two left"?

A man's saying to his wife: "Then it has occurred," or "Consider it one divorce," or "This is one"—all of these are allusive expressions (kinayat) that require intention for the divorce to take effect. Also, there should be no excessive questioning or over-elaboration of issues.
