No, just a slow machine with only one CPU. If it is a huge passed pawn bonus, then I would expect Junior to make strange moves at times. How is it that the general play is excellent? There must be some heuristic to decide when to employ the bonus and when it is a bad idea or the overall play would be damaged. In any case, I think it is the most impressive thing I ever saw a computer do. I can make crafty solve WAC.230 by giving a huge passed pawn bonus. But then it will play badly for many other positions and over all be weakened by a large amount. This was (apparently) the production version of Junior -- at least they were confident enough to run it with the settings that they chose. For sure, a wonderful achievement. That game (not that I have reviewed it) is the very sort of reason why I like computer chess a lot. They can do breathtaking things, like GMs do, from time to time.
