  Chinook (ACJ Extra)
Jonathan Schaeffer, the head of the team that created Chinook, is a 37-year-old computer scientist with a passing resemblance to the comedian and film maker Albert Brooks.
Schaeffer convinced Silicon Graphics to lend him an additional computer, the "Onyx." This machine is not as powerful as the Challenge, but in the event of difficulties with the Challenge, the Onyx would also be capable of running Chinook; the Chinook/Onyx combination plays a good game, although not as good as Chinook/Challenge.
Schaeffer was eager for a win in the latter match, so, with the instincts of a hustler, he disabled some of Chinook's new features for the Nationals, the better to keep Tinsley from knowing the new Chinook's full power until the one-on-one match itself began.

Jonathan Schaeffer is one adult who knows that computer games represent much more than just a way of killing time.
His intent is to achieve a better understanding of what it takes to build high-performance systems that operate in real time, where high-performance is defined as achieving a performance level comparable to, or better than, that of the best humans.
Rather than seeking small incremental advances that are in isolation of the domain in which the ideas could be applied, Dr. Schaeffer plans to take an application and solve all the problems necessary to achieve high performance.
