It’s a Draw!

  • Jonathan Schaeffer


Finally, we’re into the home stretch. There were still a few last-minute things to do. SGI made an eight-processor computer available to us in California (with the wistful name hawaii). Paul was still testing the parallel version of Chinook. He used the computer during the 10 P.M. to 10 A.M. shift, allowing me access to the machine during the day. I used the machine to continue my testing and search for new cooks. Martin was still poring through Chinook’s analysis of the opening book, also looking for cooks. And Rob? The critical eight-piece databases were done, so his major contribution was complete. He kept busy working on the lopsided eight-piece databases.

    One of the Tinsley-Lowder games was taking a long time to complete, but was likely to be a draw. Rather than drag it out, the players agreed to have Chinook adjudicate it. The program’s verdict? Draw.Google Scholar
