On your web page you once said that you thought that the average chess
programmer's chess knowledge was about 1400.

I think you are off by about 600 points, I think I am typical at about 2000.

But I have also studied chess as it relates to computers.  Whether or not this
has helped my over the board play, I do not know, but I am quite happy
discussing rams, duos, dispersion, distortion, and yes, majorities.

Hsu is weaker than 2000 as far as I know, but he didn't write DB's eval code,
Murray Campbell did, in consultation with players stronger than Murray, and as
far as I know, Murray is pretty strong.

The stronger ones probably do.

But even if they don't, it really doesn't matter *that* much, I think.  I don't
have pawn majority code in mine.  It is pretty complicated to write, and even
when I hash it it takes a lot of time to execute.

I get burned from not having it, I am sure.  I often have problems with
opponents having distant passers, but the cases where it is a majority that
causes problems by itself aren't that common, it seems, or at least they get
covered by other things.
