Wrong version. It wasn't from the version that would play, because nobody had that version. 2. module names mean little, particularly if they are not almost all the same. 3. I need something to look at. IE the executable that is being questioned, not an old version. IE think about looking at an old gnuchess (non-bitboard) version 4, to try to decide if version 5 is a clone (it does use bitboards). In short, the evidence was suspicious, but barely so, and there wasn't anything I would be willing to use to say "this is a clone" as compared to the cases of Bionic, Voyager and Le Petite where I did examine the executables and was convinced beyond a shadow of a doubt that they were pure copies. I'm a firm believer of "innocent until proven guilty" and the proof here is _very_ thin, based on that one email that I received. It may well be true. Or it might not be. I certainly can't form any solid opinion from what I have been given so far, either here on CCC or via private email. BTW you will note that I don't post private emails here, contrary to "some". If someone sends me something in confidence, it shall remain in confidence.
