The Fudge Factor

  • Jonathan Schaeffer


The next day, Monday, August 13, saw the start of the U.S. championship. Although my list of problems to fix in Chinook was several pages long by now, there was no time to do anything about it. Yes, some worrying problems had shown themselves in the Mississippi championship games. We just had to hope that they wouldn’t manifest themselves again. I would be very upset if a known bug cost Chinook a game. After all, I really should stay up all night and fix the bugs before the next game (equally dangerous, since I could introduce new bugs). The hectic pace, emotional swings, and high temperatures served to sap any energy Norm and I had for playing doctor with Chinook.
