Last year, after the release of Rebel 10C, Ed Schroder was involved in discussions on Rebelboard (and here, I think) regarding the differences in programming a computer for play against humans as opposed to play against other computers. At that time, Ed decided to optimize Rebel for play against humans, whereas Tiger would be more optimized for play against computers. In developing Rebel Century, he returned to Rebel 10B as his starting point. In doing this, Ed realized he would likely be sacrificing performance versus other computer programs (e.g. Fritz, Hiarcs) for the sake of improved performance versus strong humans. It appears that Ed has been successful -- Rebel Century is doing well in the GM Series and may show a FIDE rating ~2500. It doesn't seem fair, however, to then turn around and say other programs would have even higher FIDE ratings based on the computer-computer games of the SSDF.
