        I like this problem very much. Who invented it?

        ‘7 b7++’

        This is not correct answer.
        Correct answer is:

        4. b7#

        Also, why you write ++? This means double check, not checkmate. If somebody uses ++ as checkmate, it is wrong from ages before, because old people didn’t know how to write chess properly, until new generations came.

        Yup. And a great one, too. Because white has many moves to ponder.

        And what if 2…Ka8 instead of 2…Ka6? Where is the mate now?

        He explained perfectly well what the correct chess notation is. Now you can either learn to notate properly or you can be an ass (like judging from your comment you obviously are) and make up your own chess notations.
