I am pretty good at recognizing clones. At least 1/4 of all Winboard engines are a clone of something (mostly TSCP). For the previous crafty clones, I knew they were clones immediately. It is not inconceivable that Ruffian is a clone, but it is very doubtful (in my mind). Since it is a Winboard engine, what will it be a clone of? No access to the source of the professional programs. A clone of a strong Winboard program? Not inconceivable, but very doubtful, in my mind. Strings signatures do not match anywhere and features implemented are different. This person has not been working in some sort of pure isolation. He knew how to implement Nalimov tablebase files. So he would have to know about Robert's FTP site and enough about the Nalimov format to create an implementation. So there has been study of what is going on in computer chess recently. I have a strings dump in another thread. Simply put, I doubt very much if Ruffian is a clone.
