More knowledge is generally better. But knowledge also has costs. Many programs spend a significant portion of their execution time in the evaluation function. If you reduce the amount of knowledge, you can increase the search speed. Some programs are "fast but dumb" searchers and these can be quite dangerous .. they may miss subtleties but if they find a combination that wins significant material then the subtleties don't matter. I don't think you can make a top-ranked program without having both speed and significant chess knowledge, but different programs tilt one way or the other. --Jon
