But even more important, >do you remember _lots_ of discussions on ICC where you were asking Bruce and >myself questions? _and_ getting answers? I do. I usually asked Bruce questions and you jumped into the discussion. Not to put too fine a point on it, but I didn't consider your input useful. After I had developed most of my first chess program, I asked to see a certain part of Crafty. You said sure, download the source code, it's freely available. I was startled and asked if you really meant that anybody could download your source code. You said yes, it was a decision that you had recently made, and that you hadn't told anybody else that it was available yet. Then I told Bruce that Crafty was open source. He had a very hard time believing me and said that I should definitely quadruple-check it with you before I gave the ftp address to anyone. So Crafty may have been freely available before Stobor was around, but if it was, it was an extremely well-kept secret. -Tom
