If you use someone's entire program and then slowly modify it, >that is a simple crime to me. And one with no excuses. Here we disagree. I see nothing wrong with starting from some known point, so long as you eventually end up with nothing but your own code... Otherwise you will spend a long time writing all the support stuff, and many lose interest before they get far enough along to actually see their creation play any real chess... IE this is where "C" came from. Changes to "B". Etc...
