The point is that it doesn't need to know anything at all. To perform at a rating of 2800 Elo, it only needs to score on average 3-1 vs 2600 Elo, or 2-1 vs 2700, etc.BBauer wrote:This position was not about computers in general, but only about one single engine.

but doesn't even know about underpromotion.
An Elo of 2800 only means that, nothing more. An Elo isn't a diploma of knowledge, culture, or understanding. It is solely a relative rating as opposed to other ratings. If this lack of knowledge prevents it from maintaining a rating of 2800, then it won't perform at 2800 Elo. If it doesn't, then this knowledge is clearly not essential to attaining or maintaining this rating performance.
Again, Elo is solely about relative performance, nothing else.
