You don't know that. You can't extrapolate the Nimzo case to include all
programmers.

Yes, but it was his own decision, noone forced him to exclude development of
endgame play. It isn't fair to those who develop their program without the aid
of tablebases either.

The programmers can make all the assumptions they want, but that doesn't mean
that all others are forced to abide by them. Why should it be the programmers
that decide the assumptions? BTW, I don't think you know anything about the
assumptions made by programmers, except maybe Nimzo.

You're missing the point. From a scientific point of view _every_ aspect of the
computer chess game should be capable of improvement. Everything doesn't revolve
around winning or losing a chess game by all means necessary.

>It is not important in simple endgames when tablebases is a better solution.

You are wrong, it's the simplicity of the endgames that makes them interesting.
Tablebases is just a "simple" supplement capable of hiding obvious problems,
that are inherent to the program itself. Tablebases are only a temporary
solution IMO.
